Ethylene glycol CAS 107-21-1

Ethylene glycol, inozivikanwawo seglycol, ndiyo aliphatic diol iri nyore. Ine hunhu hwemakemikari hwealcohols, sekukwanisa kugadzira ethers nemaesters, kuti ioxidized kuti igadzire aldehydes kana acids, uye kuti iome kuti igadzire ethers. Inogonawo kutsiviwa nema halogens. Kana ikaita reactive ne acyl chlorides kana acid anhydrides, diesters dzinowanzo umbwa. Kana ichipiswa paine catalyst (manganese dioxide, aluminium oxide, zinc oxide kana sulfuric acid), inogona kuomeswa nemvura mukati memasero kana mukati memasero kuti igadzire cyclic ethylene glycol acetal, iyo inobatana ne nitric acid kuti igadzire ethylene glycol dinitrate (chinhu chinoputika). Ethylene glycol chinhu chakakosha pakugadzira polyester resins, alkyd resins, uye polyester fibers. Inoshandiswawo semushonga wekudzivirira kutonhora uye refrigerant yeinjini yendege.

Chitarisiko: Mvura isina ruvara, yakajeka, ine viscous

Mashandisirwo Ethylene glycol inonyanya kushandiswa sezvinhu zvisina kugadzirwa zve polyester fibers, uye inoshandiswawo mune mamwe ma polyester resins, unsaturated polyester resins uye 1730 polyester paints. Mhando dzakasiyana dzema surfactants dzinogona kubva ku ethylene glycol ne polyethylene glycol. Dinitro compound yayo dinitroethylene glycol inoputika. Ethylene glycol inogona kuderedza nzvimbo yekutonhora yemvura, saka inowanzoshandiswa sechinhu chinodzivirira kutonhora.
