Ethylene glycol CAS 107-21-1

Ethylene glycol, e tsejoang hape e le glycol, ke aliphatic diol e bonolo ka ho fetisisa. E na le litšobotsi tsa lik'hemik'hale tsa alcohols, tse kang bokhoni ba ho hlahisa li-ether le li-ester, ho oxidized ho hlahisa li-aldehydes kapa li-acid, le ho kopana ho hlahisa li-ether. E ka boela ea nkeloa sebaka ke li-halogen. Ha e arabela ka acyl chloride kapa li-anhydride tsa acid, hangata li-diester lia thehoa. Ha e futhumatsoa boteng ba catalyst (manganese dioxide, aluminium oxide, zinc oxide kapa sulfuric acid), e ka omisoa ka hare ho molecular kapa ka hare ho molecular ho hlahisa cyclic ethylene glycol acetal, e arabelang le nitric acid ho hlahisa ethylene glycol dinitrate (ntho e phatlohang). Ethylene glycol ke thepa e tala bakeng sa tlhahiso ea li-resin tsa polyester, li-resin tsa alkyd le likhoele tsa polyester. E boetse e sebelisoa e le sehatsetsi sa likoloi se thibelang ho hoama le sehatsetsing sa enjene ea lifofane.

Ponahalo: Mokelikeli o se nang 'mala, o bonaletsang, o nang le viscous

Tšebeliso Ethylene glycol e sebelisoa haholo-holo e le thepa e tala bakeng sa likhoele tsa polyester, 'me e boetse e sebelisoa li-resin tse ling tsa polyester, li-resin tsa polyester tse sa tlalang le lipente tsa polyester tsa 1730. Mefuta e fapaneng ea li-surfactants e ka fumanoa ho ethylene glycol le polyethylene glycol. Motsoako oa eona oa dinitro dinitroethylene glycol ke ntho e phatlohang. Ethylene glycol e ka fokotsa ntlha ea ho hoama ea litharollo tsa metsi, kahoo hangata e sebelisoa e le moemeli oa antifreeze.
