2454 results about "Saturated carboxylic acid" patented technology

A carboxylic acid is a molecule that contains at least one carbon double bonded to an oxygen, and single bonded to an oxygen in an OH group. The double bond means that carbon is only bonded to 3 atoms, therefore the carboxylic acid group is not saturated.

Processes of making gamma,delta-unsaturated carboxylic acid and silyl ester thereof, carboxyl group-containing organosilicon compound and process of making

A γ,δ-unsaturated carboxylic acid silyl ester is prepared by reacting an α,β-unsaturated carboxylic acid ester with a hydrosilane or hydrosiloxane in the presence of tris(pentafluorophenyl)borane. γ,δ-Unsaturated carboxylic acid derivatives are readily prepared through fewer steps and in high yields.
