Imininingwane yomkhiqizo
MF: C3H8O2
MW: 76.09
CAS: 109-86-4
1.I-Ethylene glycol monomethyl ether (efushanisiwe ngokuthi i-MOE), eyaziwa nangokuthi i-ethylene glycol monomethyl ether, iwuketshezi olungenambala olubonisa ngale, oluxubana namanzi, utshwala, i-acetic acid, i-acetone ne-DMF.Njengesixazululi esibalulekile, i-MOE isetshenziswa kabanzi emafutheni ahlukahlukene, i-cellulose acetate, i-cellulose nitrate, odayi abancibilikayo wotshwala kanye nezinsalela zokwenziwa.
2.Izincibilikisi ezomisa ngokushesha zoqweqwe lwawo kanye ne-varnish, izincibilikisi zokugcoba, ama-penetrants nama-leveling agents embonini kadayi, nazo zisetshenziselwa ukuphrinta oyinki, ukulungisa ama-sealant, nokukhiqiza amapulasitiki.Eminyakeni yamuva nje, i-MOE ibilokhu isetshenziswa kakhulu embonini yezemithi, ama-aviation jet fuel anti icing agents, ama-brake oil diluents, njll., futhi umthamo wayo ukhuphuka unyaka nonyaka.Itholakala ngokusabela kwe-ethylene oxide nge-methanol.
3.Uketshezi olukhanyayo olungenambala olunephunga elimnandi.Ihlangana namanzi, i-ethanol, i-ether, i-glycerol, i-acetone ne-N, i-N-dimethylformamide.
I-4.Itholakala ngokusabela kwe-ethylene oxide nge-methanol.Engeza i-methanol ku-boron trifluoride ether complex, engeza i-ethylene oxide ku-25-30 ℃ ngaphansi kokunyakaziswa, futhi izinga lokushisa lizokhuphuka ngokuzenzakalelayo liye ku-38-45 ℃ ngemva kokudlula.Yenza maphakathi isisombululo sokusabela esitholiwe ngesixazululo se-potassium hydrocayanide methanol ku-ph=8-9chemicalbook.Buyisa i-methanol, i-distill, bese uqoqa ingxenyenamba ngaphambi kuka-130 ℃ ukuze uthole umkhiqizo ongahluziwe.Bese uhlukanisa bese uqoqa ingxenyenamba engu-123-125 ℃, okuwumkhiqizo oqediwe.Ekukhiqizeni izimboni, i-ethylene oxide kanye ne-methanol anhydrous isabela ekushiseni okuphezulu nokucindezela okukhulu, futhi imikhiqizo yokukhiqiza ephezulu ingatholakala ngaphandle kwama-catalysts.
Isicelo
I-1.Isetshenziswa njenge-solvent enamathelayo, i-penetrant, i-ejenti yokulinganisa kanye ne-organic synthesis intermediate, futhi njengesengezo se-jet fuel.
I-2.2-methoxyethanol, eyaziwa nangokuthi i-ethylene glycol monoether, iyisithako esimaphakathi se-ethersulfonyl methyl, kanye ne-solvent ye-nitrocellulose ne-synthetic resin.
3.Lo mkhiqizo usetshenziswa njenge-solvent yamafutha ahlukahlukene, i-lignin, i-nitrocellulose, i-cellulose acetate, amadayi ancibilikayo otshwala kanye nama-synthetic resins;I-Chemicalbook, i-reagent yokunquma i-iron, i-sulfate ne-carbon disulfide, kanye ne-thinner yokugqoka, isetshenziswa ekufakweni nasekufakweni uphawu kwe-cellophane, ivanishi eyomisa ngokushesha kanye ne-koqweqwe lwawo.Ingasetshenziswa futhi njenge-ejenti yokungena neyokulinganisa embonini kadayi, noma njenge-plasticizer ne-brightener.
4.Ukunqunywa kwensimbi;I-sulfate ne-carbon disulfide reagents, esetshenziswa njengamafutha ahlukahlukene;I-Lignin;I-nitrocellulose;i-cellulose acetate;Izinto ezincibilikisa odayi abancibilikayo wotshwala nama-synthetic resins.
