A method for making methylolated hydantoins by reacting a hydantoin, a formaldehyde such as paraformaldehyde and an alkaline catalyst at conditions of temperature and pressure sufficient to induce reaction to obtain a product in essentially 100% active form. Dry methylolated hydantoin product made by this process may be stored or shipped more economically than an aqueous solution containing a methylolated hydantoin.
一种制造
甲醇化海因的方法,它是在足以引起反应的温度和压力条件下,使海因、
甲醛(如多
聚甲醛)和碱性催化剂发生反应,从而得到一种基本上是 100% 活性形式的产品。与含有
甲醇化海因的
水溶液相比,用这种工艺制作的
甲醇化海因干品的储存或运输更为经济。
