Ethylene Glycol Monoethyl Ether Acetate Nrog 111-15-9
Tau los ntawm kev sib xyaw ntawm ethylene glycol monoethyl ether thiab acetic anhydride. Sib tov acetic anhydride thiab concentrated sulfuric acid. Tom qab cua sov rau 130 ° C, maj mam ntxiv ethylene glycol monoethyl ether dropwise. Qhov kub ntawm kev sib xyaw yog khaws cia ntawm 130-135 ° C. Cov dej ntws tau ntxiv rau 1-2 teev, thiab qhov kub reflux yog 140 ° C. Tom qab txias, neutralize nrog sodium carbonate rau pH = 7-8, thiab tom qab ntawd qhuav nrog industrial anhydrous potassium carbonate. Cov desiccant tau lim tawm rau kev sib xyaw ua ke, thiab cov distillate ntawm 150-160 ° C tau sau. Fractionation raug ua dua, thiab cov feem ntawm 155.5-156.5 ° C yog sau ua cov khoom tiav. Nws kuj tuaj yeem tau txais los ntawm catalyzing ethylene glycol monoethyl ether thiab acetic acid nrog concentrated sulfuric acid thiab refluxing hauv benzene.

Nws yog siv los ua cov kuab tshuaj rau cov roj hmab, tawv, kua mem, thiab lwm yam. Nws yog siv los ua cov kuab tshuaj, thiab siv los ua cov nplaum tawv, cov tshuaj pleev xim, cov hlau kub-dip tiv thaiv xeb txheej, thiab lwm yam ua ke nrog lwm cov tshuaj. Nws tuaj yeem siv los ua cov kuab tshuaj rau cov hlau thiab cov rooj tog tsuag xim, ua cov kuab tshuaj rau txhuam xim, ua cov kuab tshuaj rau cov txheej tiv thaiv, cov xim zas, cov roj hmab, tawv, kua mem, thiab hauv kev tsim cov neeg sawv cev ntxuav tawv xws li hlau thiab iav. ua cov tshuaj reagents.
