摘要： A process for the decomposition of a cumene oxidation product mixture to produce phenol and acetone with reduced by-product formation by introducing the cumene oxidation mixture into an inlet of a decomposing vessel containing indirect heat exchange surfaces wherein the cumene oxidation product mixture and a circulating stream are admixed, reacted and cooled by passage around the indirect heat exchange surfaces.

摘要： Byproduct formation in aromatic alkylation processes is reduced when different polyalkylated aromatic compounds are first fractionated into separate streams enriched in these respective polyalkylated aromatic compounds, and the separate streams are sent to different transalkylation reaction zones, which may or may not be in the same reactor. The different transalkylation reaction zones allow for greater control of the transalkylation of the respective polyalkylated aromatic compounds, such as diisopropylbenzene (DIPB) and triisopropylbenzene (TIPB) that accompany the alkylation of benzene with propylene in a process for cumene production.
摘要翻译： 当将不同的多烷基化芳族化合物首先分馏成富含这些各自的多烷基化芳族化合物的分离的流中时，芳族烷基化方法中的副产物形成降低，并且将分离的物流送入不同的烷基转移反应区，其可以是或不在同一个反应器中。 不同的烷基转移反应区可以更好地控制各种多烷基化芳族化合物如二异丙基苯（DIPB）和三异丙基苯（TIPB）在烷基化反应过程中伴随苯与丙烯烷基化反应的烷基转移。

摘要： This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene. The effluents are passed into a dividing wall distillation column where a benzene overhead and a benzene side draw are removed and recycled. An ethylbenzene stream product stream is also removed. The remainder, largely polyethylbenzene and tar, is passed to a polyethylbenzene column for separation. The separated polyethylbenzene is recycled to the transalkylation reactor.

A second benzene recycle stream is removed from an intermediate point located between the first end and the cumene stream.
