Ethylene glycol CAS 107-21-1

Ethylene glycol, wanda aka fi sani da glycol, shine mafi sauƙin aliphatic diol. Yana da halayen sinadarai na barasa, kamar ikon samar da ethers da esters, don a haɗa su don samar da aldehydes ko acid, da kuma tarawa don samar da ethers. Hakanan ana iya maye gurbinsa da halogens. Lokacin da ake amsawa da acyl chlorides ko acid anhydrides, galibi ana samar da diesters. Idan aka dumama shi a gaban mai kara kuzari (manganese dioxide, aluminum oxide, zinc oxide ko sulfuric acid), ana iya fitar da shi cikin ƙwayoyin halitta ko kuma a cikin ƙwayoyin halitta don samar da cyclic ethylene glycol acetal, wanda ke amsawa da nitric acid don samar da ethylene glycol dinitrate (mai fashewa). Ethylene glycol abu ne da ake amfani da shi don samar da resins na polyester, resins na alkyd, da zaruruwan polyester. Hakanan ana amfani da shi azaman mai hana daskarewa da injin jirgin sama.

Bayyanar: Ruwa mara launi, mai haske, mai ɗanɗano

Amfani Ana amfani da Ethylene glycol galibi a matsayin kayan da aka yi amfani da su wajen samar da zare na polyester, kuma ana amfani da shi a wasu resin polyester, resin polyester marasa cikawa da fenti na polyester 1730. Ana iya samun nau'ikan surfactants daban-daban daga ethylene glycol da polyethylene glycol. Dinitroethylene glycol ɗinsa na dinitro yana da fashewa. Ethylene glycol na iya rage wurin daskarewa na ruwan da ke narkewa, don haka sau da yawa ana amfani da shi azaman maganin hana daskarewa.
