Ke eng Ethylene GlycolTšebeliso ea eona ke efe?
Ethylene glycol (EG), e tsejoang hape e le "glycol alcohol" kapa "1,2-ethanediol", ke diol e bonolo ka ho fetisisa e nang le foromo ea lik'hemik'hale (CH₂OH)₂. Ke mokelikeli o se nang 'mala, o se nang monko o nang le tatso e monate, chefo e tlase ho liphoofolo, le tekanyo e bolaeang e hakanyetsoang ho batho ea hoo e ka bang 1.6 g/kg.
Tšebeliso ea eona e pharaletse haholo. Bophelong ba letsatsi le letsatsi, ethylene glycol e ka fetoloa hore e be polyester le resin, e sebelisoang ho etsa li-humectant, li-moisturizer, litlolo le liqhomane, hammoho le ho sebetsa e le li-solvent le li-dehydrating agents. Liindastering, li-resin le likhoele tsa polyester tse entsoeng ka ethylene glycol li sebelisoa e le thepa e tala bakeng sa libotlolo tsa meriana le libotlolo tsa metsi, 'me li ka boela tsa etsoa li-antifreeze le li-coolant tsa indasteri.
Ethylene glycol e kopanngoa le metsi le acetone, empa e na le ho qhibiliha ho fokolang ho li-ether. E sebelisoa haholo-holo e le solvent, antifreeze, le thepa e tala bakeng sa tlhahiso ea polyester. Polymer ea eona e phahameng, polyethylene glycol (PEG), e sebetsa e le catalyst ea phetisetso ea mohato 'me e sebelisoa ho kopanngoa ha sele; nitrate derivative ea eona ke ntho e phatlohang.
Ha ethylene glycol e fetoloa polyethylene glycol, ha e sa etsa dintho tse chefo tse boletsweng ka hodimo, mme chefo ya yona e fokotseha haholo. Polyethylene glycol, polymer ya dihlahiswa tsa ethylene oxide hydrolysis, ha e na chefo ebile ha e halefise, mme e sebediswa haholo mefuteng e fapaneng ya meriana. Polyethylene glycol e boima bo tlase ba dimolek'hule e na le chefo e ngata. Tshebediso ya polyethylene glycol hodima letlalo, haholoholo tsamaiso ya mucosal, e ka baka bohloko bo halefisang. Dihlatswising tsa kantle, e eketsa bonolo ba letlalo mme e fana ka ditlamorao tse mongobo tse tshwanang le glycerin, e leng se etsang hore e lokele ho sebediswa dihlahisweng tsa tlhokomelo ya letlalo.
Ethylene glycol e kopanngoa le metsi ka tekanyo efe kapa efe. Litekanyetso tse fapaneng tsa ho kopanya li fella ka litharollo tsa antifreeze tse nang le lintlha tse fapaneng tsa ho hoama le ho belisa, e leng se etsang hore e be sesebelisoa se sebetsang ka ho fetisisa sa antifreeze.
