Magaca Alaabta：propylene oxide

Qaab molecular:C3H6O

CAS Maya:75-56-9

Qaab dhismeedka molecular Product：

Guryaha Kiimikada:

Waa iskudhis organic ah oo leh qaacidada kiimikada C3H6O. Waa walxo cayriin ah oo aad muhiim u ah isku-dhafka dabiiciga ah waana tan saddexaad ee ugu weyn ee propylene ka dib polypropylene iyo acrylonitrile. Epoxypropane waa dareere etheric ah oo aan midab lahayn, barta karkarinta hoose, guban karta, dhogorta, iyo alaabada warshaduhu guud ahaan waa isku dhafka midab-kala-sooca ee laba wax-kiciya. Qayb ahaan waa lagu qallajin karaa biyo, lagu qallajin karo ethanol iyo ether. Wuxuu sameeyaa isku dhafka azeotropic binary oo leh pentane, pentene, cyclopentane, cyclopentene iyo dichloromethane. Sun, xanaaqa xuubabka xuubka iyo maqaarka, waxay dhaawici kartaa cornea iyo conjunctiva, waxay sababi kartaa xanuunka neefsashada, gubashada maqaarka iyo bararka, iyo xitaa necrosis nudaha.

Codsiga:

Waxa loo isticmaali karaa sidii wakiilka fuuq-baxa loogu talagalay diyaarinta slides ee microscopy elektarooniga ah. dermatitis-ka shaqada ayaa sidoo kale la soo sheegay iyadoo la isticmaalayo suuf jeermiska maqaarka.

Kiimikada dhexdhexaadka ah ee diyaarinta polyeter-ka si loo sameeyo polyurethane; diyaarinta polyols urethane iyo propylene iyo glycols dipropylene; diyaarinta saliidaha, surfactants, demulsifiers saliidda. Sida dareere ah; qiiqaya; sterilant ciidda.

Propylene oxide waxaa loo isticmaalaa sida fumigat alaabta cuntada; xasiliye ahaan shidaalka, saliidaha kuleyliyaha, iyo hydrocarbons koloriin leh; aasa shidaalka – hawada qaraxda ee rasaasta; iyo xoojinta caabbinta suuska ee alwaax iyo sabuuradaha (Mallari et al. 1989). Daraasadihii ugu dambeeyay waxay muujinayaan in awoodda fumigant ee propylene oxide ay kor u qaaddo cadaadiska hoose ee 100 mm Hg taasoo ka dhigi karta asan beddelka methyl bromide ee jeermiska degdega ah ee badeecadaha.
