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.

Ethoxylated ester surfactants and a process therefor

A method for preparing 'twin-tailed' tertiary amines which have two moles of alkoxylated phenol bonded to each nitrogen function of a molecule of methylamine and represented by the formula: ##STR1## wherein x represents zero to about 30 which comprises alkylating a mole of methylamine with two moles of alkoxylated alkylphenol over a catalyst comprising:

An extractive distillation agent consisting essentially of glycerol-1,3-di-t-butylether is fed to an extractive distillation column used for the distillation of propylene oxide contaminated with water to obtain an overhead distillate fraction consisting of essentially anhydrous propylene oxide, and a heavier bottoms distillation fraction containing substantially all of the glycerol-1,3-di-t-butylether and water introduced into the distillation column.

Dehydration of propylene oxide by extracting distillation

Novel fatty amines, amides and salts thereof may be made from the reaction of polyoxyalkylenepolyamine residues with fatty acids and/or fatty acid esters under relatively mild reaction conditions in the absence of a catalyst. Remarkably, the residues or bottoms products from the synthesis of polyoxyalkylenepolyamines, such as triethylene glycol diamine and tetraethylene glycol diamine, also known as JEFFAMINE.RTM. EDR amines, may be reacted with the fatty acids and/or fatty acid esters to give materials useful in corrosion inhibitors, pigment wetting agents, mineral flotation and flocculation aids, asphalt emulsifiers, surfactants, detergents, petroleum additives, etc.

This invention discloses a family of bicyclodecyl ether sulfonates derived from dicyclopentadiene. Specifically synthesized is the compound: ##STR1## These compounds exhibit hydrotropic properties. These compounds are useful in liquid detergent formulations used in household, industrial and institutional products.

Bicyclodecyl ether sulfonates and compositions containing the same

Dicyclopentadiene sulfonate has been found to possess useful properties in liquid detergent formulations. The composition itself is not surface active, but it is an efficient hydrotrope for surface active agent compositions. It increases phase stability, reduces viscosity and prevent gelling of concentrated surfactant blends.
