The present invention provides procedures for preparation of N, N', N''-tris-(3-dimethylaminopropyl)-guanidine by addition of 3-dimethylaminopropylamine to N1, N3-bis-(3-dimethylaminopropyl)-carbodiimide. The latter compound was prepared in two steps starting from commercially available 3-dimethylaminpropyl amine and carbon disulfide followed by desulfurization of the formed thiourea with yellow mercury(II)-oxide. The so obtained guanidine derivative was successfully applied as catalyst in the transesterification of sunflower, soybean and rapeseed oil.
本发明提供了一种通过将3-二甲基氨基丙胺加入N1, N3-双(3-二甲基氨基丙基)-碳酰亚胺制备N, N', N''-三-(3-二甲基氨基丙基)-胍的方法。后一种化合物是通过从商业可获得的3-二甲基氨基丙胺和二硫化碳开始的两步法制备的,随后用二氧化汞(II)对生成的硫氨基脲进行脱硫。所得的胍衍生物成功地应用于向日葵、大豆和油菜籽油的酯交换反应中作为催化剂。
