Zomangamanga:
Azobisisobutyronitrile, AIBN mwachidule, mankhwala formula ndi C8H12N4, sungunuka mu organic solvents monga methanol, ethanol, ether, acetone, petroleum ether ndi aniline.Akatenthedwa, amamasula nayitrogeni ndi organic cyanide okhala ndi -(CH2)2-C-CN gulu.Zimawola pang'onopang'ono kutentha kwa chipinda ndipo zimawola mofulumira pa 100 ° C.Zingayambitse kuphulika ndi moto, kuyaka.chakupha.Organic cyanide yotulutsidwa imakhala yovulaza thupi la munthu.

Katundu
White crystal kapena crystalline ufa, wosasungunuka m'madzi, sungunuka mu etha, methanol, ethanol, propanol, chloroform, dichloroethane, ethyl acetate, benzene, etc., makamaka oyambitsa mafuta osungunuka.Imawola ikatenthedwa, malo osungunuka ndi 100 ℃-104 ℃.Iyenera kusungidwa pamalo ouma pa 20°C.Pakakhala chinyezi, imatulutsa nitrogen ndi organic cyanide yomwe ili ndi -(CH2)2-C-CN gulu.Kutentha kwa kutentha ndi 64 ℃.Zimawola pang'onopang'ono kutentha kwa chipinda, ndipo zimawola mofulumira pa 100 ℃, zomwe zingayambitse kuphulika ndi moto, zomwe zimayaka komanso zapoizoni.Kutulutsa nayitrogeni ndi organic cyanide, yotsirizirayi imakhala yovulaza thupi la munthu.
Ntchito
Azobisisobutyronitrile is an oil-soluble azo initiator.Woyambitsa azo ali ndi machitidwe okhazikika, ndi machitidwe oyambirira, alibe machitidwe a mbali, ndipo ndi osavuta kuwongolera, choncho amagwiritsidwa ntchito kwambiri pofufuza ndi kupanga ma polima.Monga vinilu kolorayidi, vinilu acetate, acrylonitrile ndi zina monomer polymerization oyambitsa, Angagwiritsidwenso ntchito monga polyvinyl kolorayidi, polyolefin, polyurethane, polyvinyl mowa, acrylonitrile ndi butadiene ndi styrene copolymer, polyisocyanate, polyacetate Kuwomba wothandizila, polyester vinyl ndi polyamide.Kuphatikiza apo, itha kugwiritsidwanso ntchito muzinthu zina za organic.
Kugwiritsa ntchito mankhwala
Amagwiritsidwa ntchito ngati polymerization initiator kwa monomers monga polyvinyl kolorayidi, polyvinyl mowa, polystyrene, polyacrylonitrile;monga woyambitsa wa polymerization wa vinilu kolorayidi, vinilu acetate, acrylonitrile ndi monomers ena, komanso monga mphira , Pulasitiki thobvu wothandizira, mlingo ndi 10% mpaka 20%.Izi zitha kugwiritsidwanso ntchito ngati vulcanizing wothandizira, mankhwala ophera tizilombo komanso wapakatikati mu kaphatikizidwe ka organic.Izi ndi mankhwala oopsa kwambiri, ndipo pakamwa LD5017.2 ~ 25mg/kg kwa mbewa, organic cyanide wotulutsidwa ndi kutentha kuwonongeka ndi poizoni kwambiri kwa thupi la munthu.Organic kaphatikizidwe intermediates;amagwiritsidwa ntchito ngati oyambitsa ma polima apamwamba kwambiri.
