Abstract

The current technological necessity in the oil industry is the substitution of HF and H2SO4 in the alkylation process. To this end, great research efforts have been made to develop catalysts for this reaction. Among the technological alternatives, ionic liquids seem to be the most viable solution to this problem. Here, 4-vinylpyridine-based poly(ionic liquids) carrying Brønsted and Lewis acid sites were synthesized, characterized, and evaluated as catalysts of the alkylation reaction using a real refinery paraffins/olefins feedstock. The best catalyst was poly(4-vinyl pyridine N-propyl sulfonic acid) heptachloroaluminate (P4VPyPS-Al2Cl7), which gave rise to an alkylation yield of 99.7 % and selectivity to C8 of 62.9 %.

以乙烯基吡啶为催化剂的烷基化反应聚离子液体的合成及评价
目前石油工业的技术需要是在烷基化过程中取代HF和H2SO4。为此,人们进行了大量的研究工作来开发这种反应的催化剂。在技术替代品中,离子液体似乎是解决这个问题最可行的方法。本文合成了携带Brønsted和Lewis酸位的4-乙烯基吡啶基聚离子液体,并对其作为烷基化反应的催化剂进行了表征和评价。最佳催化剂为聚(4-乙烯基吡啶n -丙基磺酸)七氯铝酸酯(P4VPyPS-Al2Cl7),烷基化率为99.7%,对C8的选择性为62.9%。

期刊介绍: The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
