Azobisisoheheptonitrile: Ibintu, Porogaramu n'umubare wumutekano

Vuba aha, Azishisiohepponitrile yongeye kuza mu jisho rusange. Iyi miti, hamwe nizina ryicyongereza 2,2'-Azbis- (2,4-Dimebeylvaleronitrile), igaragara nka kirisiti yera, ifite ingingo ishonga kuva kuri 40 kugeza 70 ℃. Nibikorwa byo gukosora amavuta hamwe ningufu zakazi za 122 KJ / Mol. Birashonga mubintu bya kama nka methanol, toluene na acetone, ariko bidahunze mumazi. Ubushyuhe bwo kubora kumasaha 10-ubuzima ni 51 ℃ (muri Toluene).

Azobisisoheheptonitrile ikoreshwa cyane muri disiki yoroheje, guhagarika polymeiriryation nigisubizo cyamasako, kandi ikoreshwa cyane mumikorere yinganda nubushakashatsi bwa siyansi. Kubera ko kuboneza bisanzwe bishoboka rwose, gukora ubwoko bumwe gusa bwubusa nta myigaragambyo, birahamye muri kamere noroshye kubika no gutwara. Ariko, twakagombye kumenya ko mugihe cyo gutwara abantu, bigomba gukonjeshwa no kurindwa gukabije no kugongana, bitabaye ibyo birashobora gutera igisasu.

Twibutse mu gitondo cya kare no ku ya 22 Nyakanga 2011, umutoza wicwa kabiri ibitambaraye kuri Weihai, Shandong yerekeza i Changsha, Hunan kuri Beijing-Zhuhai Exprow ya Acecetse. Umuriro wari ufite akababaro kuburyo watwitse umutoza ku gikonoshwa. Aya makuba yavuze ko 41 abaho kandi yakomeretse abantu 6, hamwe n'abantu 1 bakomeretse bikabije. Nyuma y'iperereza, icyateye iyi mpanuka ni igare ritemewe no gutwara imiti yaka imiti yaka Azimaheheheheheheheheheheheheheheptonitrilole ku modoka y'impanuka. Iyi miti iteje akaga iraturika mu buryo butunguranye kandi itwikwa mu bikorwa by'ibintu nk'akajagari, guterana amagambo no kurekurwa muri moteri, biganisha kuri iki kibazo giteye ubwoba. Nyuma yaho, abantu babishinzwe babishinzwe barafashwe kandi bafunzwe bafunzwe hakurikijwe amategeko. Mu Kuboza 2013, Intara y'Amajyambere n'Umurima wa Xinyang, Intara ya Henan yashyize urubanza rwa mbere kuri iyi mpanuka, abahatira abantu bashinzwe ibyaha, bashinzwe guhana ibihano ku byaha byo guhungabanya umutekano wa Leta mu buryo buteye akaga ndetse n'impanuka nyinshi zishinzwe umutekano.

Ibi byabaye byatangaje induru yumutekano wo gutwara no gukoresha Azobisisoheheptonitrile. Ibigo bireba n'abakozi bigomba kubahiriza byimazeyo amabwiriza agenga igihe bakora Azobisohehehehepponitrionitriton, menya neza ko ubwikorezi n'ububiko bujuje ibyangombwa bisa. Muri icyo gihe, abaturage nabo bagomba kongera gusobanukirwa imiti iteje akaga no kuzamura imitunganyirize.
