A low concentration aqueous solution of the agent for processing synthetic fibers is produced by preparing an acidic alkyl phosphate which is solid at room temperature and gradually adding this prepared acidic alkyl phosphate with stirring to an aqueous solution containing potassium hydroxide in an amount to partially neutralize this added acidic alkyl phosphate to obtain a 0.1-10 weight % low concentration aqueous solution of the agent for processing synthetic fibers containing potassium alkyl phosphate.
制备用于加工合成纤维的药剂的低浓度
水溶液的方法是:制备一种在室温下呈固态的酸性烷基
磷酸酯,然后在搅拌下将制备好的酸性烷基
磷酸酯逐渐加入到含有
氢氧化钾的
水溶液中,加入的量应能部分中和加入的酸性烷基
磷酸酯,以获得含有烷基
磷酸酯
钾的 0.1-10 重量%的用于加工合成纤维的药剂的低浓度
水溶液。
