WebA hydrolysis time course experimental study is highly recommended to optimize laboratory conditions best suited to particular requirements. In a recent survey (1993) of amino acid analysis test sites , the times of liquid phase hydrolysis averaged 111 ± 2.7°C for 22 ± 2.4 h and 160 ± 15°C for 1.4 ± 0.4 h for vapor-phase hydrolysis. 6. WebKetones are prepared by oxidation of secondary alcohols and hydration of alkynes. Carboxylic acids are prepared by the oxidation of primary alcohols, aldehydes and alkenes by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide. Q. 1.
