    摘要: A method for the preparation of secondary alcohol mixtures by selective reaction of an olefin or olefin mixture and a carboxylic acid compound in the presence of zeolite mordenite. The reaction selectively produces .alpha.-methylalkyl carboxylate enriched ester product which, upon subsequent hydrolysis, yields the desired secondary alcohol product enriched in alcohols having hydroxy functionality at the 2-position.

    摘要: A process for converting a methanol feed to light olefins over a zeolite catalyst comprising at least some crystalline aluminosilicate zeolitic material having a Constraint Index of about 1 to 12 and a silica/alumina mole ratio of at least about 12, e.g., ZSM-5, in the presence of diluent which provides O.sub.2 -containing gas, e.g. air, in the reaction zone under methanol conversion conditions. By using such a ZSM-5 type zeolite catalyst and an oxygen-providing diluent, methanol can be converted to an olefin-containing hydrocarbon product enriched in C.sub.2 to C.sub.4 olefins such as ethylene.

    摘要: A process for producing substantially linear hydrocarbons by oligomerizing a lower olefin at elevated temperature and pressure which comprises contacting the lower olefin under oligomerization/polymerization conditions with siliceous acidic ZSM-23 zeolite having Bronsted acid activity; wherein the zeolite has acidic pore activity and wherein the zeolite surface is rendered substantially inactive for acidic reactions. The zeolite surface can be neutralized by a bulky pyridine compound having an effective cross-section larger than the zeolite pore. The preferred deactivating agent is 2,4,6-collidine, which may be applied to the zeolite as a pretreatment or added with olefin feed in a continuous process. The olefin oligomers may be used as alkylating agents to prepare biodegradable alkylbenzenes and alkylphenylsulfonates. A preferred catalyst for this alkylation reaction is dealuminized mordenite.
