Faahfaahinta alaabta
MF: C3H8O2
MW: 76.09
CAS: 109-86-4
1.Ethylene glycol monomethyl ether (oo loo soo gaabiyo MOE), oo sidoo kale loo yaqaan ethylene glycol monomethyl ether, waa dareere hufan oo aan midab lahayn, kaas oo lagu khaldi karo biyaha, khamriga, acetic acid, acetone iyo DMF.Sida dareere muhiim ah, MOE waxaa si weyn loogu isticmaalaa saliidaha kala duwan, acetate cellulose, amooniyam cellulose, dheeha alkolada iyo xabagta synthetic.
2.Fast qalajinta qallayl ee dhaldhalaalka iyo varnish, daahan dareere ah, dhex gal iyo wakiilada siman ee warshadaha dheeha, ayaa sidoo kale loo isticmaalaa daabacaadda khad, diyaarinta shaambo, iyo wax soo saarka balaastikada.Sanadihii la soo dhaafay, MOE ayaa si sii kordheysa loogu isticmaalay warshadaha dawooyinka, shidaalka jet-ka duulista ee ka hortagga barafka, Saliida Saliidda, iwm.Waxaa lagu helaa falcelinta ethylene oxide ee methanol.
3.Dareere hufan oo aan midab lahayn oo leh ur wacan.Waxaa lagu qallajin karaa biyo, ethanol, ether, glycerol, acetone iyo N, N-dimethylformamide.
4.Waxa lagu helaa falcelinta ethylene oxide oo leh methanol.Ku dar methanol boron trifluoride ether complex, ku dar ethylene oxide 25-30 ℃ hoostiisa, heerkulku wuxuu si toos ah u kici doonaa ilaa 38-45 ℃ ka dib markaad dhaafto.Dhexdhexaad ka dhig xalka falcelinta la helay ee potassium hydrocayanide methanol xal ph=8-9 kiimikaad.Soo kabso methanol, distill, oo ururi jajabka ka hor 130 ℃ si aad u hesho alaabta ceeriin.Ka dib kala qaybi oo ururi jajabka 123-125 ℃, taas oo ah alaabta la dhammeeyey.Wax soo saarka warshadaha, ethylene oxide iyo methanol anhydrous ah ayaa looga falceliyaa heerkulka sare iyo cadaadiska sare, wax soo saarka sare ayaa la heli karaa iyada oo aan wax kicin ah.
Codsiga
1.It waxaa loo isticmaalaa sida dareere daahan, galaa, wakiilka siman iyo synthesis organic dhexdhexaad ah, iyo sidoo kale sida lagu daro shidaalka jet.
2.2-methoxyethanol, oo sidoo kale loo yaqaan ethylene glycol monoether, waa dhexdhexaadka herbicide ethersulfonyl methyl, iyo sidoo kale dareeraha nitrocellulose iyo resin synthetic.
3.Badeecadan waxaa loo isticmaalaa sida dareeraha saliidaha kala duwan, lignin, nitrocellulose, acetate cellulose, alkolada dheeha iyo resins synthetic;Kitaab kiimiko, reagent loogu talagalay go'aaminta birta, sulfate iyo kaarboon disulfide, iyo khafiifinta dahaarka, ayaa loo isticmaalaa baakadaha iyo xidhitaanka cellophane, varnish qalajinta degdega ah iyo dhaldhalaalka.Waxa kale oo loo isticmaali karaa sida wax-soo-saarka iyo wax-soo-saarka ee warshadaha dheeha, ama caagadeeyaha iyo iftiimiye.
4.Go'aaminta birta;Sulfate iyo kaarboon disulfide reagents, oo loo isticmaalo sida saliidaha kala duwan;Lignin;Nitrocellulose;Cellulose acetate;Aalkolada dheeha lagu milmo iyo resins synthetic.
