Ubumenyi bumwe na AIBN (CAS: 78-67-1)

1.Izina ry'icyongereza:2,2′-Azobis (2-methylpropionitrile)

2.Imiterere yimiti:

Inkingi yera yinkingi cyangwa ifu yera ya kirisiti.Kudashonga mumazi, gushonga mumashanyarazi nka methanol, Ethanol, acetone, ether, peteroli ether na aniline.

3. Intego:

Nkumuntu watangije polymerisation ya vinyl chloride, Vinyl acetate, acrylonitrile nizindi monomers, hamwe numukozi ubyibushye wa rubber na plastike, dosiye ni 10% ~ 20%.Iki gicuruzwa gishobora kandi gukoreshwa nkibikoresho byangiza, imiti y’ibitabo by’ubuhinzi, hamwe n’igihe gito muri synthesis.Iki gicuruzwa nikintu gifite ubumara bukabije.Umunwa LD5017.2-25mg / kg mu mbeba zirashobora gutera uburozi bukomeye kubantu bitewe no kurekura cyanide kama mugihe cyo kubora.

4.Uburyo bwo kubyara:

Acetone, hydrazine hydrate na Sodium cyanide ikoreshwa nkibikoresho fatizo: ubushyuhe bwa reaction ya Condensation yavuzwe haruguru ni 55 ~ 60 ℃, igihe cyo kubyitwaramo ni 5h, hanyuma gukonja kugeza 25 ~ 30 ℃ kuri 2h.Iyo ubushyuhe bugabanutse munsi ya 10 ℃, chlorine iratangizwa kandi reaction iba munsi ya 20 ℃ mubitabo bya Chemical.Ikigereranyo cyibikoresho ni: HCN: acetone: hydrazine = 1L: 1.5036kg: 0.415kg.Acetone cyanohydrin ifata hydratine hydratine, hanyuma igahindura okiside hamwe na chlorine y'amazi cyangwa aminobutyronitrile hamwe na Sodium hypochlorite.

5.Ubushyuhe bwo gutangiza

AIBN nintangarugero idasanzwe ya Radical.Iyo ashyushye kugeza kuri 70 ° C, izabora kandi irekure azote kandi itange radical yubusa (CH3) 2CCN.Ubusa radical irahagaze neza bitewe ningaruka zitsinda rya cyano.Irashobora kwitwara hamwe nubundi buryo bwa organic substrate hanyuma igahinduka muburyo bushya bwubusa mugihe irimbuye ubwayo, bityo bigatera Urunigi reaction ya radicals yubusa (reba Free Radical Reaction).Muri icyo gihe, irashobora kandi guhuzwa na molekile ebyiri na Chemical Book kugirango itange tetramethyl Succinonitrile (TMSN) ifite uburozi bukomeye.Iyo ushyushye AIBN kugeza kuri 100-107 ° C, irashonga kandi ikangirika vuba, ikarekura gaze ya azote hamwe nuburozi bwa nitrile nyinshi bwangiza, bishobora no gutera guturika no gutwikwa.Buhoro buhoro kubora mubushyuhe bwicyumba hanyuma ubike munsi ya 10 ° C. Irinde ibishashi nubushyuhe.Uburozi.Metabolised muri aside hydrocyanic mubice byinyamanswa nkamaraso, umwijima, nubwonko.

6.Ububiko no gutwara ibintu:

Classification Ibyiciro byuburozi: Uburozi

Ibiranga ibyago biturika: birashobora guturika iyo bivanze na okiside;Biroroshye okiside, idahindagurika, ibora cyane munsi yubushyuhe, kandi iturika Chemical Book iyo ishyutswe na heptane na acetone

Characteristics Ibiranga ibyago byo gutwika: Birashya imbere yumuriro ufunguye, ubushyuhe bwinshi, hamwe na okiside;Yangiza imyuka yaka iyo ihuye n'ubushyuhe;Gutwika bitanga umwotsi wa azote oxyde

Ibiranga kubika no gutwara ibintu: guhumeka ububiko, kumisha ubushyuhe buke;Ubike ukwe na okiside

Agent Kuzimya umukozi: amazi, umucanga wumye, karuboni ya dioxyde, ifuro, 1211 yo kuzimya
