Ubumenyi bumwe kuri AIBN (RAS: 78-67-1)

1.Izina ry'icyongereza:2,2'-AZbis (2-methylroPioritrile)

2.Imiti:

Inkoko yera kristu cyangwa ifu yera Crystal. SHAKA MU MAZI, GUSOHORA MU BIKORWA BY'INGENZI NA Methanol, Ethanol, Acetone, Ether, Pethele, Petroleum Ether na Aniline.

3.Kora:

Nkumucunga utangiza amaganga ya chloride ya vinyl, vinyl a Iki gicuruzwa nacyo gishobora gukoreshwa nkigikorwa cya gilcanies, ubuhinzi bwa chimial Ibicuruzwa nibintu byuburozi cyane. Oral ld5017.2-25mg / kg mu rubibe birashobora gutera uburozi bukomeye kubantu kubera kurekura kama kama mugihe cyuzuyemo ubushyuhe.

4. Uburyo bwiza:

Acetone, Hydrazine hydrate na sodium cyanide bakoreshwa nkibikoresho fatizo: Ubushyuhe bwa Condensition ya 55 ~ 60 ℃, igihe cyimyitwarire ni 5 ~ 30 ℃ kuri 2h. Iyo ubushyuhe bugabanutse munsi ya 10 ℃, chlorine itangijwe kandi reaction ibera munsi ya 20 ℃ mumiti. Igipimo cyibikoresho ni: HCN: Acetone: Hydrazine = 1L: 1.5036kg: 0.415kg. Acetone cyanohydrin yitabye hydrazine hydrate, hanyuma ukandagira hamwe na chlorine cyangwa aminobutyronitrile na sodium hypochlorite.

UMURYANGO W'INGENZI

AIBN numubare mwiza cyane. Iyo nko gushyuha kuri 70 ° C, bizabora no kurekura azote no kubyara imirasire yubusa (ch3) 2Ccn. Umusaruro wubusa urahagaze neza kubera ingaruka za cyano. Irashobora kubyitwaramo hamwe nindi sumburangingo kama kandi ivuguruye muburyo bushya bwubusa mugihe arimbukiranya, bityo bituma urunigi rwimiti rwubusa (reba reaction idasanzwe). Mugihe kimwe, irashobora kandi guhuzwa na molekile ebyiri na chimicale kugirango itange tetramethyl succinonitrile (TMSN) ifite uburozi bukomeye. Mugihe ushyushya AIBN kugeza 100-107 ° C, ishonga kandi igabora vuba, kurekura gaze yihuse, yo hejuru ya nitrile ibice byinshi byuburozi, bishobora kandi gutera ibisasu no gutwikwa no gutwika. Buhoro buhoro kubora ubushyuhe bwo mucyumba no kubika munsi ya 10 ° C. Irinde ibishishwa nubushyuhe. Uburozi. Metamolize muri aside ya hydrocyanic mu ngingo z'inyamaswa nkamaraso, umwijima, n'ubwonko.

6.Gutangwa no gutwara abantu:

Icyiciro cy'uburozi: Uburozi

② ibiranga ibyago biturika: birashobora guturika mugihe uvanze na Oxidants; Byoroshye kuri okiside, idahungabana, kubora cyane mubushyuhe, kandi isebanya igitabo cya chimika mugihe ashyushye na Heptane na acetone

③ Akabaho Akababurindi karangaga: Akabahwa imbere yumuriro ufunguye, ubushyuhe bwinshi, nubushake bwa okiside; Kubora imyuka yaka iyo yahuye n'ubushyuhe; Gutwika Amashanyarazi Ubumara

Ibiranga no gutwara abantu: Guhumeka ububiko, ubushyuhe-buke bwumuka; Ubike utandukanye kuva kuri Oxidants

Gusohoza umukozi: Amazi, Umucanga wumye, Dioxyde Dioxyde, ifuro, 1211 yo kwizihiza umukozi
