Ethoxylation of stearic acid
WebA series of fatty acid monoethanolamide ethoxylates was synthesized. Tensiometry and fluorescence were used to study the solution behavior of this surfactant series. The effec of the amide bond, the effect of unsaturations in the hydrocarbon chains, and the effects of the oxyethylene chain length were investigated. WebSep 1, 2024 · The alkoxylation may typically be ethoxylation or propoxylation, or a mixture of both. Where a nitrogen atom is alkoxylated, a preferred average degree of alkoxylation is from 10 to 30, preferably from 15 to 25 alkoxy groups per modification. ... palmitic acid or stearic acid; and fatty acid mixtures in which 50 to 100% (by weight based on the ...

Web1. PEG-n Stearate is made by esterification of stearic acid and PEG-n under acid catalysis. The catalyst is neutralized following esterification. 2. Stearic acid can undergo direct … Ethoxylation is a chemical reaction in which ethylene oxide adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC2H4)nOH where n ranges from 1 to 10. Such compounds are called alcohol ethoxylates. Alcohol ethoxylates are often converted to related species called ethoxysulfates. Alcohol ethoxylates and ethoxysulfates are s…
WebCresylic acid ethoxylation is catalyzed by basic compounds and salts of alkaline earth metals. Ethoxylates from such reactions have narrow ethylene oxide distributions, lower pour points and lower by-products as compared to alkali base catalyzed ethoxylation. Suitable catalysts include strontium-containing and barium-containing materials.

WebThe resulting ethoxylate is converted to a half ester of sulfuric acid, which is neutralized by conversion to the sodium salt. [1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step.
