Adding an appropriate amount of water to dimethyl hydantoin, control the temperature at about 30 ℃ for stirring of 30min until all the dimethyl hydantoin is dissolved. Add drop wise of appropriate amount of bromine within a certain period of time and then have reaction for several hours. After the completion of the reaction, cool the solution, crystallize using ethanol, filter, and dry with the light-yellow solid being finished product of DBDMH.<BR/> <img src="/NewsImg/2016-07-30/20167301356622875.jpg" alt="" /><br /> The optimal condition for experimentally determination and synthesis of DBDMH is: the optimum molar ratio of DMH to bromine is 1: 2.0; the solvent amount is 80 mL (water) /0.1mol (Hein); the reaction temperature should be about 30 ℃; Reaction time is around 5min with the yield of 1,3-dibromo-5,5-dimethylhydantoin being up to 80%.
