1,3-Diaminopropane, also known as trimethylenediamine, is a simple diamine with the formula (CH2)3(NH2)2. A colourless liquid with a fishy odor, it is soluble in water and many polar organic solvents. It is isomeric with 1,2-diaminopropane. Both are building blocks in the synthesis of heterocycles, such as those used in textile finishing, and coordination complexes. It is prepared by the amination of acrylonitrile followed by hydrogenation of the resulting aminopropionitrile.

生产方法
将1份二溴丙烷与8-9份在0℃饱和氨和乙醇溶液混溶,放置3-4d。蒸干,剩余物加碱液后蒸馏。馏出物用盐酸中和。蒸浓,冷却,将浓缩液干燥使盐酸盐结晶析出。用碱分解盐酸盐,蒸馏出1,3-丙二胺。 溶剂、净化剂、医药中间体、农药中间体、染料中间体。KAPA制备的起始材料，分子末端异构化用强碱基。
