PROCESS FOR THE PREPARATION OF 1,3-BIS(ALLYLAMINO)PROPANE
A process for the preparation of 1,3-bis(allylamino)propane is provided. According to one aspect, the process for the preparation of 1,3-bis(allylamino)propane includes i) forming a reaction mixture containing allylamine (CH 2 ═CH 2 CH 2 NH 2 ) and a difunctional propane, (ii) separating a 1,3-bis(allylamino)propane product from the reaction mixture, and (iii) recovering any excess, unreacted allylamine from the reaction mixture.
1 . A process for the preparation of 1,3-bis(allylamino)propane, the process comprising i) forming a reaction mixture containing allylamine (CH2=CH2CH2NH2) and a difunctional propane, (ii) separating a 1,3-bis(allylamino)propane product from the reaction mixture, and (iii) recovering any excess, unreacted allylamine from the reaction mixture, wherein the process is selected from the group consisting of a batch process, semi-continuous process, and continuous process.
