【Abstract】 With development and utility of adiponitrile tar dregs to prod- uce hexanedioic acid and through contract tests between the extraction anddry distillation methods comes the best one, that is the dry distillation meth-od. It is the simple process and economical in using of the chemical materials of alcohol and ketone,and it has better efficiency economically and socially.更多还原
