The effectiveness of molybdenum dialkyldithiocarbamates (I) and di-μ-thio-dithio-bis (dialkyldithiocarbamates) dimolybdenum (II) as antioxidants in the autoxidation of squalane was investigated and compared with zinc dialkyldithiocarbamate. Induction periods of doped squalane were measured using an automatic recording oxygen absorption apparatus.These compounds show efficient inhibition action and give sharply defined induction periods, there being an abrupt change in O2 uptake rate. It has been found that the potency as oxidation inhibitor of molybdenum compound (I) and (II) is the same irrespective of their degree of sulfurization. It seems, therefore, that the alkyl group play an important role in the activity of oxidation inhibition.It has been experimentally found that zinc and molybdenum compounds (I, II) act as peroxide decomposer for tert-butyl hydroperoxide in chroloform solution and squalane hydroperoxide. Seemingly, capacity of molybdenum compounds (I, II) to decompose hydroperoxide is higher than that of zinc dialkyldithiocarbamate. For autoxidation of squalane initiated by azobisisobutyronitrile, the influence of zinc compound on the rate of oxidation is much more pronounced than the molybdenum compounds (I, II).Therefore, it may be concluded that molybdenum compounds (I, II) suppress the autoxidation of squalane by acting as catalytic peroxide decomposer; on the other hand zinc dialkyldithiocarbamate by terminating the propagation of the oxidative chain reaction.
研究了二烷基二硫代氨基甲酸钼(I)和二μ-硫-二硫-双(二烷基二硫代氨基甲酸酯)二钼(II)作为抗氧化剂对角鲨烷自氧化的效果,并与二烷基二硫代氨基甲酸锌进行了比较。使用自动记录吸氧仪测量了掺杂角鲨烷的诱导周期。这些化合物表现出有效的抑制作用,并有明确的诱导期,有氧摄取速率的突变。发现钼化合物(I)和(II)作为抗氧化剂的效力与硫化程度无关。因此,烷基似乎在氧化抑制活性中起重要作用。实验发现锌和钼化合物(I, II)对氯仿溶液中的过氧化氢叔丁基和过氧化氢角鲨烷起过氧化物分解剂的作用。表面上看,钼化合物(I, II)分解过氧化氢的能力高于二烷基二硫代氨基甲酸锌。对于偶氮二异丁腈引发的角鲨烷自氧化反应,锌化合物对氧化速率的影响比钼化合物(I, II)要明显得多,因此可以认为钼化合物(I, II)通过催化过氧化分解者的作用抑制了角鲨烷的自氧化反应;另一方面,二烷基二硫代氨基甲酸锌通过终止氧化链反应进行增殖。

Evaporation losses of hydrocarbons from various sources, such as refinery plants, oil terminals and gas stations, were studied. A correlation involving the volume of discharged gas, temperature and hydrocarbon concentration was derived for crude oil and petroleum products. These gas emission sources were classified according to their mode of evaporation. As a result, hydrocarbon emission factors in terms of annual mean value were obtained for various emission sources, such as cone and floating roof tanks, loading tankers, tank trucks and gas stations; and also the hydrocarbon emission factors far crude oil and such petroleum products as naphtha, gasoline, kerosene, diesel oil and fuel oil. The hydrocarbon emission factors obtained in this study were smaller than those presented by the U. S. EPA.The calculated hydrocarbon emission factor for loading a tanker which was calculated for the first time, was less than 1/5 of that for loading a tank truck. The hydrocarbon emission factor for loading various kinds of vessels with kerosene and diesel oil was about 1/500 of that for loading the same types of vessels with gasoline.

Steam reforming of hydrocarbons is generally used for production of town gas and synthetic gas. Continuous steam reforming under high pressure seems most economical, but its disadvantage is the deposition of carbon that made operation under the most economical steam/oil ratio difficult. But this difficulty has been removed by the development of alkalized nickel catalyst by ICI Co., Ltd. S. P. S. Andrew1) has reported that this catalyst consists of a refractory support and mobil alkali which accelerates the reaction between steam and the deposited carbon. It is further found that kalsilite (K.Al.SiO4) is the most desirable alkali source for the alkalized nickel catalyst.

Effects of Acid-Base Properties of MoO3-Bi2O3-P2O5 Catalysts on Oxidation Activity and Selectivity MoO3-Bi2O3-P2O5催化剂酸碱性质对氧化活性和选择性的影响
Pub Date : 1974-11-25 DOI: 10.1627/JPI1959.16.118

The vapor-phase oxidation of cis-2-butene, 1, 3-butadiene, acetic acid, and hydrogen were carried out over various MoO3-Bi2O3-P2O5 catalysts with different Bi2O3 contents. Oxidation activity is compared with dehydration activity for 2-propanol, and the ratios of (dehydrogenation rate)/(dehydration rate) for 2-propanol which were used as measures of acidity and basicity of the catalysts. The acidity of the catalysts increases with an increase in the Bi2O3 content and attains a maximum at about Bi/(Mo+Bi)=0.1. The basicity is very low for Bi2O3-poor composition, but sharply increases, with an increase in Bi2O3 at Bi/(Mo+Bi)>0.5. It has been found that oxidation and isomerization activities for olefins are associated with acidity of the catalyst and that oxidation activity for acidic compounds and activation and adsorption of oxygen are associated with basicity. Selectivity for olefin oxidation is also discussed from the viewpoint of the acid-base nature of the reactant and catalyst.
在不同Bi2O3含量的MoO3-Bi2O3-P2O5催化剂上进行了顺式-2-丁烯、1,3 -丁二烯、乙酸和氢的气相氧化反应。比较了2-丙醇的氧化活性和脱水活性,并将2-丙醇的脱氢率/脱水率比值作为催化剂的酸度和碱性指标。催化剂的酸度随Bi2O3含量的增加而增加,在Bi/(Mo+Bi)=0.1时达到最大值。当Bi2O3含量较差时,其碱度很低,但在Bi/(Mo+Bi)>0.5时,其碱度急剧增加。烯烃的氧化和异构化活性与催化剂的酸度有关,而酸性化合物的氧化活性和氧的活化和吸附与碱度有关。从反应物和催化剂的酸碱性质出发,讨论了烯烃氧化的选择性。

Tokuyama Soda has developed a new process for direct hydration of propylene to isopropanol in liquid phase. This process employs a highly active and selective catalyst system which essentially comprises an aqueous solution of polytungsten compounds within a selective pH range.The first commercial plant, having a capacity of 30, 000 metric tons of isopropanol per annum, has been successfully in operation since the beginning of June 1972 at Tokuyama Soda Co., Ltd.The features of the process are simpleness, low value for propylene consumption and freedom from environmental pollution problems. These advantages make Tokuyama Process by far more economical than the conventional process for the manufacture of isopropanol.

dehydroxylation; disproportionation and isomerization reactions were also detected in the advance stages of hydrocracking. CoO-MoO3 supported on Al2O3 (cat-A) favoured dehydroxylation over demethylation and NiO supported on MgO(cat-B) favoured demethylation over dehydroxylation. Disproportionation and isomerization reactions were more pronounced by cat-A than by cat-B. Products detected were phenol, toluene, 2,6-dimethylphenol, 2,4-dimethylphenol and m-, p-xylenes.

Isooctenyl alcohols were prepared from hydrolysis of diisobutylene monochlorides which were obtained by chlorination of diisobutylene. Analysis and identification of diisobuylene monochloride and isooctenyl alcohol and hydrolysis of the diisobutylene monochloride to isooctenyl alcohol in the presence of alkalis and solvents were studied. The following results were obtained.(1) Structures of the products were determined by the comparison of their IR and NMR spectra with those of authentic compounds. The diisobutylene monochloride contained 1-chloro-2-neopentyl-2-propene, cis-1-chloro-2, 4, 4-trimethyl-2-pentene, trans-1-chloro-2, 4, 4-trimethyl-2-pentene and 3-chloro-2, 4, 4-trimethyl-1-pentene, and the isooctenyl alcohol contained 2-neopentyl-2-propene-1-ol, cis-2, 4, 4-trimethyl-2-pentene-1-ol, trans-2, 4, 4-trimethyl-2-pentene-1-ol and 2, 4, 4-trimethyl-1-pentene-3-ol.(2) Reaction conditions in the presence of alkalis were studied. Among the alkalis used, sodium carbonate, sodium bicarbonate and calcium hydroxide gave favorable results, and the optimum pH value was in the range of 8∼11. When a strong alkali such as sodium hydroxide was used, favorable results were obtained by keeping pH at 8∼10.(3) DMSO was found to be one of most effective solvents in that the rate of hydrolysis was high and primary isooctenyl alcohols were obtained in high selectivity.(4) The kinetic studies showed that hydrolysis of monochloride was of the SN2 type.(5) Examination of the product composition during hydrolysis in DMSO showed that secondary monochloride changed to primary isooctenyl alcohols by isomerization. The reaction path of four isooctenyl chlorides, which were contained in the monochloride, was discussed.

Asano, Youji Komatsu","doi":"10.1627/JPI1959.15.161","DOIUrl":"https://doi.org/10.1627/JPI1959.15.161","url":null,"abstract":"Isooctenyl alcohols were prepared from hydrolysis of diisobutylene monochlorides which were obtained by chlorination of diisobutylene. Analysis and identification of diisobuylene monochloride and isooctenyl alcohol and hydrolysis of the diisobutylene monochloride to isooctenyl alcohol in the presence of alkalis and solvents were studied. The following results were obtained.(1) Structures of the products were determined by the comparison of their IR and NMR spectra with those of authentic compounds. The diisobutylene monochloride contained 1-chloro-2-neopentyl-2-propene, cis-1-chloro-2, 4, 4-trimethyl-2-pentene, trans-1-chloro-2, 4, 4-trimethyl-2-pentene and 3-chloro-2, 4, 4-trimethyl-1-pentene, and the isooctenyl alcohol contained 2-neopentyl-2-propene-1-ol, cis-2, 4, 4-trimethyl-2-pentene-1-ol, trans-2, 4, 4-trimethyl-2-pentene-1-ol and 2, 4, 4-trimethyl-1-pentene-3-ol.(2) Reaction conditions in the presence of alkalis were studied. Among the alkalis used, sodium carbonate, sodium bicarbonate and calcium hydroxide gave favorable results, and the optimum pH value was in the range of 8∼11. When a strong alkali such as sodium hydroxide was used, favorable results were obtained by keeping pH at 8∼10.(3) DMSO was found to be one of most effective solvents in that the rate of hydrolysis was high and primary isooctenyl alcohols were obtained in high selectivity.(4) The kinetic studies showed that hydrolysis of monochloride was of the SN2 type.(5) Examination of the product composition during hydrolysis in DMSO showed that secondary monochloride changed to primary isooctenyl alcohols by isomerization. The reaction path of four isooctenyl chlorides, which were contained in the monochloride, was discussed.","PeriodicalId":9596,"journal":{"name":"Bulletin of The Japan Petroleum Institute","volume":"87 1","pages":"161-171"},"PeriodicalIF":0.0,"publicationDate":"1974-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79878125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
