Kapangidwe kake ndi kapangidwe kake ka N, N-dimethylbenzylmine

Fomu: N,N-dimethylbenzylamine ndi madzi owonekera opanda mtundu kapena achikasu chopepuka.

Fungo: Lili ndi fungo la ammonia.

Kusungunuka: Kusakaniza ndi mowa ndi ether, kusungunuka m'madzi otentha, kusungunuka pang'ono m'madzi ozizira.

Chiyero ndi Chinyezi: Chiyero chake nthawi zambiri chimakhala ≥98% kapena kupitirira apo, monga 99%, 99.5%, ndipo chinyezi chimakhala ≤0.05% kapena ≤0.2%.

Zina mwa zinthu zakuthupi: Malo osungunuka ndi pafupifupi -75°C, malo owira ndi 183-184°C (kapena 178-184°C, 178-181°C, ndi zina zotero), kuchuluka kwake ndi pafupifupi 0.9 g/mL, ndipo chizindikiro cha refractive ndi pafupifupi 1.501 (kapena 1.495-1.503).

N,N-dimethylbenzylamine imagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala. Nthawi zambiri imagwiritsidwa ntchito ngati chothandizira, choletsa dzimbiri, komanso choletsa kuzizira. Imagwiritsidwanso ntchito popanga zinthu zachilengedwe, monga chothandizira kuchiritsa epoxy resin komanso kupanga mchere wa quaternary ammonium. Posungira ndi kunyamula, zofunikira za mankhwala oopsa owononga ziyenera kutsatiridwa kuti zitsimikizire kuti ndi otetezeka.

N,N-dimethylbenzylamine (BDMA) ndi mankhwala achilengedwe omwe amagwiritsidwa ntchito kwambiri m'magawo ambiri.

Makampani a Polyurethane: Monga chothandizira kupanga thovu lofewa la polyester polyurethane block, thovu lolimba ndi zokutira zomatira, imagwiritsidwa ntchito kwambiri pa thovu lolimba. Likhoza kusintha kusinthasintha koyambirira ndi kufanana kwa maselo a thovu la polyurethane, ndikuwonjezera thovu ndi maziko. Kumamatira kwa zinthu.
Munda wa epoxy resin: Monga cholimbikitsira asidi anhydride, imagwiritsidwa ntchito pokonzekera zokutira za epoxy resin zopanda solvent. Imalimbikitsa acid anhydride yokonzedwa bwino ya bisphenol A epoxy resin ndipo imagwiritsidwa ntchito kwambiri mu zipangizo zamagetsi zopangira miphika, zinthu zozungulira, ndi zina zotero.
Kupanga kwachilengedwe: Kumagwiritsidwa ntchito ngati chothandizira kuchotsa ma halogenation ndi asidi kuti apange mankhwala achilengedwe. Kumagwiritsidwanso ntchito popanga mchere wa ammonium wa quaternary ndikupanga fungicides wamphamvu wa cationic surface-active, ndi zina zotero.

Kuphatikiza apo, N,N-dimethylbenzylamine ingagwiritsidwenso ntchito ngati chothandizira kuchotsa ma hydrogenation, chosungira, ndi zina zotero. Posungira ndi kunyamula, zofunikira za mankhwala oopsa owononga ziyenera kutsatiridwa kuti zitsimikizire kuti ndi otetezeka.
