Abstract
Methods for preparation of a unique superbase catalyst consisting of mixture of polyether alcohol and base in which a polyether alcohol superbase is produced by the removal of water or alcohol at elevated temperatures to form a polyether alcohol alkoxide. The superbase catalyst is useful in, but not limited to, quantitative isomerization of alkyl esters of vegetable oils containing interrupted double bond systems to yield esters with conjugated double bond systems, alkylations, arylations, acylations, aminations, condensations, eliminations, isomerizations, rearrangements, and Wittig reactions.
