A process for producing alkoxylated mono-, di-, and tri-esters in which a starting material ester and an alkylene oxide are reacted in the presence of selected calcium based catalysts.

Process for alkoxylation of esters and products produced therefrom

A process for reducing volatile, odor-causing impurities in alkoxylated alcohols comprising adjusting the pH of an alkoxylated alcohol product mixture containing such impurities to a range of from about 7 to about 8.5 to produce an alkaline alkoxylated alcohol mixture and steam stripping the alkaline alkoxylated alcohol mixture at an elevated temperature for a period of time sufficient to produce a steam stripped alkoxylated alcohol containing a reduced amount of odor-causing impurities.

Process for purification of alkoxylated alcohols

A process for preparing an alkoxylation catalyst in which a catalyst is formed by admixing an alkoxylated alcohol with a calcium or strontium containing compound which is dispersible in the alkoxylated alcohol, an inorganic acid and a titanium alkoxide, the pre-mix optionally being heated to a temperature and for a time sufficient to effect at least partial exchange reaction between the alkoxide groups of the titanium alkoxide and the hydroxyl groups of the alkoxylated alcohol, the pre-mix being used in an alkoxylation process to alkoxylate active hydrogen containing compounds such as alcohols.

Alkoxylation process

A process for producing alkoxylated methyl esters to produce a narrow homolog distribution of the alkoxylate species in which a staring material methyl ester and an alkylene oxide are reacted in the presence of selected calcium based catalysts.
