PREPARATION OF PENTENOIC ACID |
摘要 |
3-pentenoic acid or the R ester of pentenoic acid is produced by treating pentenoyl chloride in a reactive distillation zone with ROH where R is hydrogen or hydrocarbon of 1 to 6 carbon atoms. Butadiene may be reacted with HCl that is formed by the hydrolysis of pentenoyl chloride, and the butadiene converted to chlorobutene, and the chlorobutene reacted with carbon monoxide to form pentenoyl chloride. |
