ABSTRACT:
A process for producing ethoxylated ester surfactants in high yield has been discovered which employs no halogen-containing reactants or intermediates. Allyl alcohol is reacted with ethylene oxide to give an allyl alcohol ethoxylate; the ethoxylate in turn is reacted with a bisulfite salt (e.g. sodium metabisulfite) to give an ethylene glycol propanesulfonate or polyethylene glycol propanesulfonate in high yield. The propanesulfonate is then reacted with a fatty acid to give the ethoxylated ester surfactant.
