摘要： A new methodology for the synthesis of a novel difunctional- and a known trifunctional initiator, i.e., 1,3-di(2-methoxy-2-propyl)-5-isopropyl benzene and 1,3,5-tri(2-methoxy-2-propyl) benzene, respectively, for the preparation of di- and tri-telechelic polyisobutylenes. The synthesis proceeds in three steps: 1) catalytic peroxidation of 1,3,5-triisopropylbenzene, 2) reduction of the peroxides to the corresponding alcohols, and 3) methylation of the alcohols. By controlling the conversion of the key peroxidation step the relative ratio of di- and tri-fiinctional intermediates can be controlled. By the use of the 1,3-di(2-methoxy-2-propyl)-5-isopropyl-benzene, well-defined di-methoxy telechelic polyisobutylenes can be synthesized. Although the overall combined yield of the two initiators was only 14-20%, because of the low cost of the starting material, reagents used, and simple manipulations these compounds represent the most cost effective initiators to-date for the preparation of telechelic polyisobutylenes.

摘要： The purpose of the present invention is to provide an advantageous non-barbotage method for oxidation of aromatic hydrocarbons, that, when implemented in various embodiments thereof, provides significantly higher selectivity, a greater level of safety, Sower capital costs, etc., than conventional oxidation processes utilizing the barbotage technique. The essence of the inventive non-barbotage oxidation process is ensuring that the oxidizing agent delivered to the process reactor undergoes continued contact only with exposed surfaces of the liquid phase of the hydrocarbons being oxidized configured as at least one of: formed liquid phase thin film(s), liquid phase continuous stream(s), and/or liquid phase globule (e.g., droplets, etc.) stream(s), preferably, with the surface area(s) of the exposed surface(s) being maximized to increase contact with an oxidizing agent being directed thereto, to ensure that the inventive oxidation reaction occurs at the border between liquid and gas phases, such that the oxidation reaction effectively occurs by way of contact of the oxidizing agent (e.g., oxygen) from the gas phase with exposed surface(s) of the liquid phase of the hydrocarbons being oxidized. The inventive non-barbotage oxidation process may be implemented in a single reactor, or in plural sequential reactors, and may be implemented both in a stand-alone configuration, and in combination with various conventional barbotage methods for oxidation of aromatic hydrocarbons.
摘要翻译：本发明的目的是提供用于芳族烃氧化的有利的非阻塞方法，当其在各种实施方案中实施时，与常规方法相比，提供了显着更高的选择性，更高的安全性水平，更低的资金成本等利用barbotage技术的氧化过程。本发明的非强制氧化工艺的实质是确保输送到工艺反应器的氧化剂仅与被氧化的烃的液相的暴露表面连续接触，所述暴露表面被配置为形成的液相薄膜（ s），液相连续流和/或液相小球（例如液滴等）流，优选地使暴露表面的表面积最大化以增加与导向其的氧化剂接触，以确保本发明的氧化反应发生在液相和气相之间的边界，使得氧化反应通过氧化剂（例如氧气）与气相接触而有效地发生烃的液相的暴露表面被氧化。本发明的非破坏氧化过程可以在单个反应器中或在多个连续反应器中实施，并且可以以独立构造实施并且与用于氧化芳香烃的各种常规破碎方法结合实施。
