| Abstract: | Tertiary butylurea was prepared by the reaction of urea and tertiary butyl alcohol in presence of sulfuric acid and ammonia as rielltralization agent.The influencing factors on the reaction were studied and the optimum process conditions were as follows:n(sulfuric acid):n(urea):n(tertiary butyl alcohol)= 2.0:1.0:1.0,tertiary butyl urea was prepared by the reaction of urea and tertiary butyl alcohol,the reaction time is 16 h between tertiary butyl alcohol and urea at15~25℃,the yield of tertiary butylurea was more than 90﹪.The structure of tertiary butylurea was assigned by IR and 1HNMR. |
