Lubricant compositions for use in automotive engine oils comprising a combination of a specific base stock or mixture of base stocks and a friction reducing additive to improve fuel economy and fuel economy longevity of the automotive engine oil. The friction reducing additive is a specific partial polyol ester and may also include a specific saturated primary amide.

Automotive lubricant composition

Large pore size zeolites produced with organic cations in the synthesis mixture are synthesized with high silica:alumina ratios by terminating the crystallization when the product is partly crystalline, preferably 30% to 90 % crystalline by X-ray diffraction measurement. The method is particularly useful with zeolite beta to produce a partly crystalline product with higher silica:alumina ratio by direct synthesis.

Method for producing highly siliceous zeolites

This invention relates to a new and improved form of crystalline silicate having the structure of zeolite Beta, to a new and useful improvement in synthesizing said crystalline silicate and to use of said crystalline silicate prepared in accordance herewith as a catalyst for organic compound, e.g. hydrocarbon compound, conversion.

Process for the preparation of zeolite Beta using

A novel process for the preparation of ZSM-5 and ZSM-11 utilizing a mixture of both quaternary ammonium ions and amines in the forming solution is disclosed in order to enhance the rate of crystallization.
