I-Ethylene glycol CAS 107-21-1

I-ethylene glycol, ekwaziwa ngokuba yi-glycol, yeyona diol ilula kakhulu ye-aliphatic. Ineempawu zeekhemikhali ze-alcohols, ezinje ngokukwazi ukuvelisa ii-ether kunye nee-esters, ukuze i-oxidized ukuvelisa ii-aldehydes okanye ii-asidi, kwaye ijike ivelise ii-ether. Ingathathelwa indawo zii-halogens. Xa isabela kwi-acyl chloride okanye ii-anhydride ze-acid, ii-diesters zihlala zenziwa. Xa ishushu phambi kwe-catalyst (i-manganese dioxide, i-aluminium oxide, i-zinc oxide okanye i-sulfuric acid), ingasuswa emanzini ngaphakathi okanye ngaphakathi ukuze ivelise i-cyclic ethylene glycol acetal, esabela kwi-nitric acid ukuvelisa i-ethylene glycol dinitrate (into eqhumayo). I-ethylene glycol sisixhobo esiluhlaza sokuvelisa ii-polyester resins, ii-alkyd resins, kunye neefayibha ze-polyester. Ikwasetyenziswa njenge-antifreeze yemoto kunye ne-aircraft engine refrigerant.

Inkangeleko: Ulwelo olungenambala, olucacileyo, olunencasa

Ukusetyenziswa I-Ethylene glycol isetyenziswa kakhulu njengezinto eziluhlaza kwiifayibha ze-polyester, kwaye ikwasetyenziswa nakwezinye ii-polyester resins, ii-polyester resins ezingagcwaliyo kunye neepeyinti ze-polyester ze-1730. Iindidi ezahlukeneyo ze-surfactants zinokufunyanwa kwi-ethylene glycol kunye ne-polyethylene glycol. I-dinitro compound yayo i-dinitroethylene glycol iyaqhuma. I-Ethylene glycol inokunciphisa iqondo lokuqandisa lezisombululo zamanzi, ngoko ke isetyenziswa rhoqo njenge-arhente yokuthintela ukuqandisa.
