Abstract
1,2-Diaminopropane is an important intermediate in organic synthesis.It has wide application in many fields,including fine chemicals,medicine,dye,pesticide and etc.The suitable technical conditions for synthesizing 1,2-diaminopropane from waste liquid of 1,2-dichloropropane were investigated in detail.The optimal reaction conditions were:water as solvent catalyst concentration 1% of the amount of 1,2-dichloropropane,molar ratio of ammonia to 1,2-dichloropropane 40∶1,reaction temperature 160 ℃,and reaction time 240 min.The yield of 1,2-diaminopropane could be over 50%.
