- Method for preparing a theobromine (by machine translation)
-
The present invention provides a kind of theobromine the preparation method is as follows: the caffeine by adding the alkali solution, coffee is obtained by reacting the carboxylic acid; the stated caffeinum carboxylic acid reaction with the sodium, is theobromine carboxylic acid; the said therbromine reaction of carboxylic acid and strong alkali, closed-loop generation theobromine sodium salt; the the said therbromine sodium salt with weak acid neutralization, be theobromine. This invention can be obtained through the four-step theobromine, simple process, shorten the production cycle is short. Experimental results show that, the method of the present invention to achieve preparation theobromine the yield of 48% - 50%, the yield is high. (by machine translation)
