    摘要: Dispersant detergent additives for lubricating oils prepared by neutralization, carboxylation, sulfurization-overalkalinization, carbonation, distillation, filtering and degassing from alkyl phenols containing 35-85% by weight of linear alkyl substituents. The process does not require, during the neutralizing phase, the presence of a third solvent, which, by forming an azeotropic mixture with water promote the elimination of water arising from the neutralizing reaction. The additives of the invention have improved stability to hydrolysis and improved dispersion properties, improved compatibility and improved foaming properties.

    摘要: A method is disclosed for preparing crystalline aluminosilicate zeolite L from a reaction mixture containing only sufficient water to produce zeolite L. In one embodiment, the reaction mixture is self-supporting and may be shaped if desired. In the method, the reaction mixture is heated at crystallization conditions and in the absence of an added external liquid phase, so that excess liquid need not be removed from the crystallized product prior to drying the crystals.
