Abstract: Organic sulfonic acid hydrazides are accelerators for aerostable anaerobically-setting adhesive compositions. They can be used with stabilizers. Preferred hydrazides of this group are the aryl sulfonic acid hydrazides, for example benzene sulfonic acid hydrazide. These provide rapid setting time with good ultimate strength, and have little adverse effect on the storage stability of the compounds when access of air is permitted.

Abstract: This invention relates to an improvement in the process of alkoxylation of compounds containing alcoholic hydroxyl groups by reacting compounds containing hydroxyl groups with alkylene oxides in the presence of alkoxylation catalysts. The said improvement involves the use of a tertiary oxonium salt with a substantially non-polarizable halogeno-complex anion as the said alkoxylation catalyst. Use of such catalysts gives lower amounts of unreacted alcohols in the products, particularly when secondary alkanols of 8 to 24 carbon atoms are employed.
