摘要: Disclosed herein is a process and catalyst for producing a monoalkylated aromatic compound from a polyalkylated aromatic compound, comprising the step of contacting an alkylatable aromatic compound with a polyalkylated aromatic compound under at least partial liquid phase conditions in the presence of a zeolite beta catalyst having a phosphorus content in the range of 0.001 wt.% to 10.0 wt.% of said catalyst, to provide a product which comprises a monoalkylated aromatic compound.

摘要: Disclosed is a process for the conversion of acyclic C5 feedstock to a product comprising cyclic C5 compounds, such as for example, cyclopentadiene, and catalyst compositions for use in such process. The process comprising the steps of contacting said feedstock and, optionally, hydrogen under acyclic C5 conversion conditions in the presence of a catalyst composition to form said product. The catalyst composition comprising a microporous crystalline ferrosilicate, a Group 10 metal, and, optionally, a Group 11 metal, in combination with an optional Group 1 alkali metal and/or an optional Group 2 alkaline earth metal.

摘要: A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4 alkylating agent under alkylation conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an alkylation effluent comprising secbutylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4 alkylating agent is supplied to each of the reaction zones. A secbutylbenzene fraction is recovered from the alkylation effluent and comprises at least 95 wt% sec-butylbenzene, less than 100 wt ppm of C8+ olefins, and less than 0.5 wt% of isobutylbenzene and tert-butylbenzene. The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketone.
