摘要
介绍了利用催化氧化法提高粗环烷酸的酸值。主要是采用两次蒸馏及皂化、催化氧化、酸化等化工单元过程,将酸值为90.84mgKOH/g的粗环烷酸,提高到酸值为174mgKOH/g.
That the crude naphthenic acid value is raised with the catalytic oxidizing method is introduced. The petrochemical unit courses of twice distillation, saponification, catalytic oxidizing, acidizing, etc. being used, the value of crude naphthenic acid is increased from 90.84 mgKOH/g to 174mgKOH/g.
