Abstract

The solubility of d-psicose in 15 pure solvents, including methanol, ethanol, n-propanol, isopropanol, n-butanol, 2-butanol, n-amyl alcohol, n-hexyl alcohol, acetonitrile, ethyl formate, methyl acetate, ethyl acetate, butyl acetate, acetone, and 2-butanone, was determined by the gravimetric method in the temperature range of 283.15–323.15 K. The solubility of d-psicose was the highest in methanol and the lowest in acetonitrile. At the temperature of 298.15 K, the solubility of d-psicose in alcohol solvents is as follows: methanol > ethanol > isopropanol > n-propanol >2- butanol > n-butanol > n-amyl alcohol > n-hexyl alcohol. The solubility in the esters is as follows: ethyl acetate > ethyl formate > methyl acetate > butyl acetate. The solubility in ketone solvents is as follows: acetone >2-butanone. The modified Apelblat model, λh model, nonrandom two-liquid (NRTL) model, and Van’t Hoff model were used to analyze the solubility data of d-psicose in 15 pure solvents. The solvent effect of d-psicose in the measured solvent was investigated by KAT-LSER model. The results show that hydrogen bond acidity and Hildebrand solubility parameters have important effects on the solubility of d-psicose. The thermodynamic properties of the mixing process were calculated according to the NRTL equation, which shows that the mixing process is spontaneous and entropy-driven.

温度为 283.15 至 323.15 K 时 D-壁虎糖在 15 种纯溶剂中的溶解度测定及相关性分析

在 283.15-323.15 K 的温度范围内，采用重量法测定了 d-麦角糖在甲醇、乙醇、正丙醇、异丙醇、正丁醇、2-丁醇、正戊醇、正己醇、乙腈、甲酸乙酯、乙酸甲酯、乙酸乙酯、乙酸丁酯、丙酮和 2-丁酮等 15 种纯溶剂中的溶解度。在甲醇中的溶解度最高，在乙腈中的溶解度最低。在 298.15 K 的温度下，d-麦角糖在醇类溶剂中的溶解度如下：甲醇；乙醇；异丙醇；正丙醇；2-丁醇；正丁醇；正戊醇；正己醇。在酯类中的溶解度如下：乙酸乙酯；甲酸乙酯；乙酸甲酯；乙酸丁酯。在酮类溶剂中的溶解度如下：丙酮>2-丁酮。采用改进的阿佩尔布拉特模型、λh模型、非随机双液（NRTL）模型和Van't Hoff模型分析了双水苏在15种纯溶剂中的溶解度数据。利用 KAT-LSER 模型研究了 d-麦角糖在所测溶剂中的溶剂效应。结果表明，氢键酸度和希尔德布兰德溶解度参数对麦角糖的溶解度有重要影响。根据 NRTL 方程计算了混合过程的热力学性质，结果表明混合过程是自发和熵驱动的。

期刊介绍： The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
