Ethylene Glycol Monoethyl Etere Acetate Nge 111-15-9
Ifunyenwe ngokusabela kwe-ethylene glycol monoethyl ether kunye ne-acetic anhydride. Xuba i-acetic anhydride kunye ne-concentrated sulfuric acid. Emva kokufudumeza ukuya kwi-130°C, kancinane yongeza i-ethylene glycol monoethyl ether dropwise. Ubushushu bokusabela bugcinwa kwi-130-135 ° C. Ukuhamba kongezwa kwi-1-2 h, kwaye ukushisa kwe-reflux kwakuyi-140 ° C. Emva kokupholisa, nciphisa nge-sodium carbonate ukuya kwi-pH = 7-8, uze wome nge-industrial anhydrous potassium carbonate. I-desiccant yahluzwa ngenxa ye-fractionation ekrwada, kwaye i-distillate phakathi kwe-150-160 ° C yaqokelelwa. Ukuqhekeka kuqhutyelwa kwakhona, kwaye isahlulo kwi-155.5-156.5 ° C iqokelelwa njengemveliso egqityiweyo. Inokufunyanwa kwakhona nge-catalyzing ethylene glycol monoethyl ether kunye ne-acetic acid ene-sulfuric acid egxininisiweyo kunye ne-refluxing kwi-benzene.

Isetyenziswe njenge-solvent ye-resin, isikhumba, i-inki, njl. Isetyenziswe njenge-solvent, kwaye isetyenziswe njenge-adhesive yesikhumba, i-peint stripper, i-metal hot-dip anti-corrosion coating, njl. ngokudibanisa nezinye iikhompawundi. Ingasetyenziselwa ukunyibilikisa isinyithi kunye nefenitshala yokutshiza ipeyinti, njengesinyibilikisi sepeyinti yebrashi, njengesinyibilikisi sezinto ezikhuselayo, iidayi, iireyini, isikhumba, ii-inki, kunye nasekuqulunqweni kwezinto zokucoca iindawo ezinzima ezifana nentsimbi kunye neglasi. . njengee-reagents zeekhemikhali.
