摘要:
The process for manufacturing a nylon-type polyamide from a dinitrile, a diamine and water in the presence of a catalyst is improved by using as a catalyst an ester of oxygenated phosphorus compound in conjunction with a strong base. For example, high quality nylon-6,6 is manufactured by contacting adiponitrile, hexamethylene diamine and water with an ester of an oxygenated phosphorous compound and sodium hydroxide at an elevated temperature and pressure.
