N,N-dimethyl-1,3-propanediamine (yomwe tsopano ikutchedwa DMAPA) ndi diamine yotsika ya aliphatic yokhala ndi magulu a amino atatu komanso oyambira mu molekyulu. Ndi madzi opanda mtundu komanso owonekera bwino okhala ndi fungo la ammonia. Amasuta mumlengalenga ndipo amasungunuka m'madzi ndi zinthu zosungunulira zachilengedwe. Fomula yake ya molekyulu ndi C5H14N2 ndipo fomula yake yomangira ndi (CH3)2NCH2CH2CH2NH2.
Ndi imodzi mwa mitundu yofunika kwambiri ya mafuta amine komanso chinthu chofunikira kwambiri chachilengedwe. Imagwiritsidwa ntchito kwambiri mu mankhwala a tsiku ndi tsiku, mankhwala ophera tizilombo, utoto, ma resin, ndi zina zotero. Pakadali pano, DMAPA yambiri ku China imagwiritsidwa ntchito makamaka pokonzekera betaine ndi amidopropyldimethylamine, zomwe zimagwiritsidwa ntchito pazinthu za tsiku ndi tsiku monga shampu, shawa gel, baby shower gel, conditioner, sopo wamadzimadzi ndi sopo wothira. Kuphatikiza apo, DMAPA imagwiritsidwanso ntchito ngati chothandizira polyurethane, epoxy resin curing agent ndi accelerator, komanso popanga utoto.

Njira yayikulu yopangira DMAPA ndi iyi: 1. Pogwiritsa ntchito dimethylamine ndi acrylonitrile ngati zopangira, dimethylaminopropionitrile (DMAPN) imapezeka kudzera mu Michael addition. Pokonzekera DMAPN m'mafakitale, pafupifupi 2% ya unyinji wonse wa zopangira nthawi zambiri amawonjezeredwa m'madzi kuti alimbikitse kuwonjezeredwa ndikuchotsa dimethylamine yochulukirapo azeotropically; 2. DMAPN yomwe imapezeka mwa kusungunuka mu gawo loyamba imasinthidwa ndi hydrogen pang'onopang'ono pansi pa kupanikizika kwakukulu. Kukonzekera DMAPA

Mu gawo lachiwiri la hydrogenation kuti mukonzekere DMAPA, padzakhala reaction yosiyana. Zochokera ku reaction iyi makamaka ndi amine yachiwiri bis-DMAPA ndi tertiary amine tri-DMAPA. Pakadali pano, kupanga DMAPA m'nyumba kumagwiritsa ntchito kettle reaction, ndipo hydrogenation catalyst ndi ufa wa Raney nickel. Pofuna kuletsa kupangika kwa chowonjezera ichi, ndikofunikira kuwonjezera 12%-16% ya catalyst mass ya caustic alkali aqueous solution kapena liquid ammonia, caustic alkali aqueous solution ndi liquid ammonia. Kugwiritsa ntchito kudzapanga madzi ambiri otayika ndi madzi otayika, omwe ndi ovuta kuwawononga ndikuwakonza, zomwe zimawonjezera ntchito yokonza pambuyo pake.

Zambiri zamalumikizidwe
