MF: C3H8O2
MW: 76.09
CAS: 109-86-4
1. Ethylene glycol monomethyl ether (faapuupuuina o le MOE), e lauiloa foi o le ethylene glycol monomethyl ether, o se vai manino le lanu, lea e faʻafefiloi ma le vai, ava malosi, acetic acid, acetone ma DMF.I le avea ai o se solvent taua, o loʻo faʻaaogaina lautele le MOE i suauʻu eseese, cellulose acetate, cellulose nitrate, vailaʻau soluble ava ma resins synthetic.
2. Faʻamamago faʻamago solvents mo enamel ma varnish, diluents coating, penetrants ma leveling agents i le alamanuia vali, o loʻo faʻaaogaina foi mo le lolomiina o inks, saunia sealants, ma le gaosiga o plasticizers.I tausaga talu ai nei, ua faʻateleina le faʻaaogaina o le MOE i le falemaʻi vailaʻau, vaalele vaʻavaʻa faʻamaʻi faʻamaʻi faʻamaʻi, faʻamaʻi suauu taofi, ma isi, ma o lona fua ua faʻateleina i lea tausaga ma lea tausaga.E maua mai i le tali atu o le ethylene oxide ma le methanol.
3.Colorless manino vai ma manogi manaia.E fa'afefiloi ma vai, ethanol, eter, glycerol, acetone ma N, N-dimethylformamide.
4.E maua mai i le tali atu o le ethylene oxide ma le methanol.Fa'aopoopo le methanol ile boron trifluoride ether complex, fa'aopopo le ethylene oxide ile 25-30 ℃ i lalo ole fa'aosoina, ma ole a otometi lava ona oso a'e le vevela ile 38-45 ℃ pe a uma.Fa'ate'a le vaifofo fa'afofoga na maua ile vaifofo ole methanol ole potassium hydrocayanide ile ph=8-9chemicalbook.Toe fa'afo'i le methanol, fa'a'a'a'a, ma ao mai le vaega ninii a'o le'i oo i le 130 ℃ e maua ai le oloa mama.Ona vaevae lea ma aoina le vaega 123-125 ℃, o le oloa maeʻa.I le gaosiga o fale gaosi oloa, o le ethylene oxide ma le anhydrous methanol e faʻaalia i le maualuga o le vevela ma le maualuga o le mamafa, ma e mafai ona maua oloa maualuga e aunoa ma ni faʻamalosi.
Fa'atatauga
1. E faʻaaogaina e avea o se mea faʻapipiʻi faʻapipiʻi, penetrant, leveling agent ma organic synthesis intermediate, faʻapea foʻi ma se faʻaopoopoga mo suauʻu vaalele.
2.2-methoxyethanol, e taʻua foi o le ethylene glycol monoether, o le vaeluagalemu o le herbicide ethersulfonyl methyl, ma le solvent o le nitrocellulose ma le resin synthetic.
3.O lenei oloa o loʻo faʻaaogaina e avea o se solvent mo suauʻu eseese, lignin, nitrocellulose, cellulose acetate, vailaʻau soluble ava ma resini gaosia;Chemicalbook, o se reagent mo le fuafuaina o le uʻamea, sulfate ma carbon disulfide, ma se thinner mo coatings, e faʻaaogaina i le afifiina ma le faʻamaufaʻailogaina o le cellophane, faʻamago vave varnish ma enamel.E mafai foi ona faʻaaogaina e pei o le penetrant ma leveling agent i alamanuia vali, poʻo le plasticizer ma brightener.
4. Determination o le uamea;Sulfate ma carbon disulfide reagents, faʻaaogaina e fai ma suauʻu eseese;Lignin;Nitrocellulose;Cellulose acetate;Solvents mo vali e mafai ona solu le ava malosi ma resini gaosia.
