  • Process for preparing alkynecarboxylic acids by oxidation of alkyne alcohols
    Patent number: 7173149
    Abstract: A process for preparing alkynecarboxylic acids includes the oxidation of an alkyne alcohol with a hypohalite in the presence of a nitroxyl compound at a pH of greater than 7 with continual addition of the alkyne alcohol and of the hypohalite to the reaction mixture.
    Type: Grant

  • Preparation of alkynecarboxylic acids and alkyne alcohol esters of alkynecarboxylic acids by oxidation of alkyne alcohols
    Publication number: 20030158439
    Abstract: A process for preparing alkynecarboxylic acids and alkyne alcohol esters of alkynecarboxylic acids, includes an oxidation reaction of an alkyne alcohol with from 1 to 10 molar equivalents of a hypohalite based on the number of functional groups to be oxidized in the presence of a nitroxyl compound at a pH of less than 7. There is also a partial oxidation reaction of the alkyne alcohol with from 0.5 to 5 molar equivalents of a hypohalite based on the number of functional groups to be oxidized in the presence of a nitroxyl compound at a pH of less than 7.
