Ethylene glycol monomethyl ether (hu ua MOE), tseem hu ua ethylene glycol methyl ether, yog cov kua tsis muaj xim thiab pob tshab, sib xyaw nrog dej, cawv, acetic acid, acetone thiab DMF. Ua ib qho tshuaj tseem ceeb, MOE yog siv dav ua cov tshuaj rau ntau yam roj, cellulose acetates, cellulose nitrates, cawv-soluble dyes thiab cov khoom siv hluavtaws.

Daim ntawv thov ntau lawm

1. Txoj kev npaj

Tau los ntawm kev sib xyaw ntawm ethylene oxide thiab methanol. Ntxiv methanol rau hauv boron trifluoride ether complex, thiab hla mus rau hauv ethylene oxide ntawm 25-30 ° C thaum do. Tom qab ua tiav qhov kev hla, qhov kub thiab txias yuav nce mus txog 38-45 ° C. Cov tshuaj sib xyaw ua ke tau kho nrog potassium hydrocyanide - Neutralize cov tshuaj methanol rau pH = 8-9Chemicalbook. Rov qab methanol, distill nws, thiab sau cov feem ua ntej 130 ° C kom tau txais cov khoom nyoos. Tom qab ntawd ua cov feem ua ke, thiab sau cov feem 123-125 ° C ua cov khoom tiav. Hauv kev tsim khoom lag luam, ethylene oxide thiab anhydrous methanol tau sib xyaw ntawm qhov kub thiab siab tsis muaj catalyst, thiab cov khoom lag luam siab tuaj yeem tau txais.

2. Cov kev siv tseem ceeb

Cov khoom no siv ua cov kuab tshuaj rau ntau yam roj, lignin, nitrocellulose, cellulose acetate, cov xim yaj hauv cawv thiab cov resins hluavtaws; ua cov tshuaj reagent rau kev txiav txim siab ntawm hlau, sulfate thiab carbon disulfide, ua cov tshuaj diluent rau cov txheej, thiab rau cellophane. Hauv cov khoom ntim khoom, cov varnishes qhuav sai thiab cov enamels. Nws kuj tseem siv tau ua tus neeg sawv cev nkag mus thiab tus neeg sawv cev leveling hauv kev lag luam zas xim, lossis ua cov yas thiab cov xim ci. Ua ib qho nruab nrab hauv kev tsim cov organic compounds, ethylene glycol monomethyl ether feem ntau yog siv hauv kev tsim cov acetate thiab ethylene glycol dimethyl ether. Nws tseem yog cov khoom siv raw rau kev tsim cov bis (2-methoxyethyl) phthalate plasticizer. Cov sib xyaw ntawm ethylene glycol monomethyl ether thiab glycerin (ether: glycerin = 98: 2) yog cov roj dav hlau tub rog uas tuaj yeem tiv thaiv kev icing thiab kev xeb kab mob. Thaum ethylene glycol monomethyl ether siv ua tus neeg sawv cev tiv thaiv kev loj hlob ntawm roj dav hlau, qhov ntxiv dav dav yog 0.15% ± 0.05%. Nws muaj hydrophilicity zoo. Nws siv nws tus kheej hydroxyl pawg hauv cov roj los cuam tshuam nrog cov dej me me hauv cov roj. Kev tsim ntawm hydrogen bond association, ua ke nrog nws qhov qis qis heev, txo qhov khov ntawm dej hauv cov roj, ua rau cov dej los ua te. Ethylene glycol monomethyl ether kuj yog ib qho tshuaj tiv thaiv kab mob.

Ntim, khaws cia thiab thauj mus los

Lub tsev rau khoom muaj cua nkag thiab ziab ntawm qhov kub qis; khaws cia cais ntawm cov tshuaj oxidants.
