titleOfInvention | Production method of glycoluril |
abstract | (57) Abstract: An aqueous glyoxal solution is added to an aqueous solution containing 10 to 50% by weight of urea or a mixed aqueous solution of urea and glyoxal and a saturated suspension of glycoluril in the presence of an acid catalyst. The urea / glyoxal molar ratio in the total reaction amount is 2.01-2.3, and the reaction temperature is 5 The reaction is performed under the conditions of 0 to 100 ° C., and after separating glycoluril by filtration, the reaction solution is circulated to the reactor to continuously produce glycoluril. According to the method of the present invention, glyoxal and urea are reacted to produce glycoluril and a high-concentration suspension thereof, which are highly pure and effective as a slow-release fertilizer, in a high yield and economically. It is possible to obtain continuously. |
