  The present invention relates to a process to prepare propylene amines of the formula NH2-(A-NH-)pR, wherein R is a hydrogen atom or an alkyl group, p is at least 1 when R is an alkyl group, and at least 2 when R is a hydrogen atom, or derivatives or precursors thereof wherein one or more units -NH-A-NH-may be present as a cyclic urea unit. (I) or a cyclic unit (ll) or between two units –NH-A-NH-a carbonyl bond is present, each unit –A-can be independently an alkylene unit and at least one unit –A-is a -C3H6- unit, wherein each -C3H6- unit can be linear or branched, by reacting (i) at least one of a hydroxy-functional compound chosen from the alkanolamine-functional compounds, and dihydroxyalkylene compounds, with (ii) an amine-functional compound,in the presence of (iii) a carbon oxide delivering agent, wherein at least one of the alkanolamine-functional compound, the amine-functional compound and/or the carbon oxide delivering agent contains at least one alkylene unit (A) that is a propylene unit

  本发明涉及一种制备丙烯胺的方法，其化学式为NH2-(A-NH-)pR，其中R是氢原子或烷基，当R是烷基时，p至少为1，当R是氢原子时至少为2，或其衍生物或前体，其中一个或多个单位-NH-A-NH-可以作为环状尿素单位存在。其中一个或两个单位之间存在一个羰基键，每个单位-A-可以独立地是一个烷基单位，至少一个单位-A-是一个-C3H6-单位，其中每个- -单位可以是直链或支链，通过在(i)至少一种从烷基胺基化合物和二羟基烷基化合物中选择的羟基官能化合物之一，与(ii)胺基官能化合物反应，在(iii)碳氧化物传递剂的存在下，其中至少一种烷基胺基化合物、胺基官能化合物和/或碳氧化物传递剂含有至少一个丙烯基(A)单位。
