    Abstract: The reaction of isobutylene and methylal to form a mixture 1,3dimethoxy-3-methyl butane and 4-methoxy-2-methylbutene-1 and rearrangement of the same to yield isoprene and methanol is disclosed herein. The isobutylene and methylal may be obtained by the oxidation of isobutane to form t-butylhydroperoxide, followed by rearrangement of the hydroperoxide to yield methylal and tbutyl alcohol and dehydration of the alcohol to produce isobutylene.

    Abstract: Alumino-silicate zeolites (preferably zeolites containing polyvalent metal cations) can be used to catalyze alkyl transfer, e.g., isomerization, transalkylation and disproportionation of alkylnaphthalenes. The ''''water'''' content of the zeolite and the reaction conditions (particularly temperature and space velocity) can be selected so as to favor one such reaction over the others. The preferred zeolites are at least 10 percent crystalline by Xray, can adsorb benzene, and have an atomic ratio Al/Si in the range of 1.0-0.1. One preferred zeolite has the faujasite framework structure (e.g., Linde Type Y) and contains rare earth cations (e.g., Ce and/or La etc.).

    Abstract: A reaction system is disclosed for reacting an alkylaromatic with a conjugated alkadiene, employing a dispersed catalyst such as alkali metal, to produce mainly mono-adduct product. The system includes a stirred reactor, or a plurality of stirred reactors in series, through which the liquid alkylaromatic containing dispersed catalyst is passed. Each reactor has an alkadiene supply line adjustably extending therein with its outlet positioned within the liquid during normal operation and movable to above the liquid prior to shut-down. Means are further provided for supplying an inert gas to each supply line in place of alkadiene prior to shut-down. By this arrangement plugging due to polymerization of alkadiene within the supply line can be avoided.

    Abstract translation: 公开了使烷基芳族化合物与共轭二烯烃反应的反应体系，使用分散的催化剂如碱金属，主要生产单加成产物。 该系统包括搅拌反应器或串联的多个搅拌反应器，使含有液体烷基芳族化合物的分散催化剂通过该反应器。 每个反应器具有可调节地延伸的链烷二烯供应管线，其出口在正常操作期间定位在液体内，并且在关闭之前可移动到液体上方。 进一步提供用于在关闭之前将惰性气体供应给每个供应管线代替二烯烃的装置。 通过这种安排，可以避免由于供应管线内的二烯烃聚合引起的堵塞。
