由己二腈残渣制己二酸的研究

Study of Producing Adilic Acid With Adiponitrile Residual

研究了用NaOH、HCi、H2SO4水解己二猪残渣，用H2SO4水解减压蒸出的已二腈已二酸的工艺．从经济效益、环境保护等诸方面加以比较，确定了用48％H2SO4水解减压蒸出的己二腈制己二酸的较佳工艺．

The author studied the process of hydrolyzing adiponitrile residual with NaOH,HCland H2SO4 and the process of producing adilic acid by hydrolysis of adiponitrilc distillatcd through depreessurc with H2SO4. The author made a comparison of the factors in economy and environment protection through experiments and obtained a better process of producing adilic acid with H2SO4 of 48%by hydrolysis of adiponitrile distillated under depreessurc.
