Azobisisoheptonitrile: Kadarorin, Amfani da Gargaɗin Tsaro

Kwanan nan, azobisisoheptonitrile ya sake bayyana a bainar jama'a. Wannan sinadari mai suna 2,2′-Azobis-(2,4-dimethylvaleronitrile), ya bayyana a matsayin farin lu'ulu'u, tare da zafin narkewa daga 40 zuwa 70℃. Shi ne mai farawa mai narkewar mai tare da kuzarin kunnawa na 122 KJ/mol. Yana narkewa a cikin sinadarai masu narkewa kamar methanol, toluene da acetone, amma ba ya narkewa a cikin ruwa. Zafin ruɓewa a rabin rai na awanni 10 shine 51℃ (a cikin toluene).

Ana amfani da Azobisisoheptonitrile galibi a cikin polymerization mai yawa, dakatar da polymerization da kuma polymerization mai mafita, kuma ana amfani da shi sosai a cikin samar da masana'antu da binciken kimiyya. Tunda ruɓewar sa kusan gaba ɗaya martani ne na farko, yana samar da nau'in free radicals guda ɗaya kawai ba tare da halayen gefe ba, yana da kwanciyar hankali a yanayi kuma yana da dacewa don ajiya da jigilar kaya. Duk da haka, ya kamata a lura cewa yayin jigilar kaya, yana buƙatar a sanyaya shi a cikin firiji kuma a kare shi daga gogayya mai tsanani da karo, in ba haka ba yana iya haifar da fashewa.

Da yake tunawa da safiyar ranar 22 ga Yuli, 2011, wata motar bas mai hawa biyu da ke tafiya daga Weihai, Shandong zuwa Changsha, Hunan a kan titin Beijing-Zhuhai Expressway ta kama da wuta ba zato ba tsammani. Gobarar ta yi tsanani har ta kone motar har ta zama babu komai. Wannan bala'in ya yi sanadiyyar mutuwar mutane 41 tare da raunata mutane 6, yayin da mutum 1 ya ji rauni mai tsanani. Bayan bincike, musabbabin hatsarin shine abin hawa ba bisa ka'ida ba da jigilar sinadarin azobisisoheptonitrile mai kama da guba a cikin motar hatsarin. Waɗannan sinadarai masu haɗari sun fashe ba zato ba tsammani suka ƙone a ƙarƙashin tasirin abubuwa kamar fitar da hayaki, gogayya da fitar da zafi daga injin, wanda ya haifar da wannan mummunan lamari.

Wannan lamari ya yi ta yawo a kafofin watsa labarai game da amincin sufuri da amfani da azobisisoheptonitrile. Kamfanoni da ma'aikata masu dacewa dole ne su bi ƙa'idodi masu dacewa yayin gudanar da azobisisoheptonitrile, tabbatar da cewa yanayin sufuri da ajiya sun cika buƙatun, da kuma guje wa sake afkuwar irin wannan bala'i. A lokaci guda kuma, jama'a ya kamata su ƙara fahimtarsu game da sinadarai masu haɗari da kuma wayar da kan jama'a game da tsaro.
