摘要
对二苯胍的制备工艺进行了研究，即用氧化锌作脱硫剂，在 ０． ２～ ０． ３ Ｍ Ｐａ的压力下，由 Ｎ，Ｎ＇－二苯基硫脲合成二苯肌。对最佳工艺条件及工艺条件对收率的影响进行了研究。
in this paper, the technology of producing diphenyl guanidine is investigated. Diphenyl guanidine is prepared by diphenylthiourea, zinc oxide using as desulphurizator, liquid ammonia as aminator, and under the pressure of 0.2 ~ 0.3 M Pa. Optimal technical conditions and their effecting on the product yield have been researched.
