Product details
MF: C3H8O2
pwm: 76.09
CAS: 109-86-4 Nr
1.ethylene glycol monomethyl etherry (abbrene glycole, yog ua rau dej tsw qab, cawv, acetic acid, acetone thiab dmf.Raws li cov kuab tshuaj tseem ceeb, MOE tau siv dav hauv ntau cov roj, cellulose acetate, cellulose nitrate, cawv soluble dyes thiab hluavtaws resins.
2.Fast drying solvents rau enamel thiab kua roj vanish, coating diluents, penetrants thiab leveling agents nyob rau hauv kev lag luam dyeing, kuj yog siv rau printing inks, npaj sealants, thiab manufacturing plasticizers.Nyob rau hauv xyoo tas los no, MOE tau siv ntau dua hauv kev lag luam tshuaj, aviation dav hlau roj los tiv thaiv icing agents, nres roj diluents, thiab lwm yam., thiab nws cov koob tshuaj tau nce xyoo los ntawm xyoo.Nws tau txais los ntawm cov tshuaj tiv thaiv ntawm ethylene oxide nrog methanol.
3.Colorless pob tshab kua nrog qab ntxiag tsw.Nws yog miscible nrog dej, ethanol, ether, glycerol, acetone thiab N, N-dimethylformamide.
4.Nws yog tau los ntawm cov tshuaj tiv thaiv ntawm ethylene oxide nrog methanol.Ntxiv methanol rau boron trifluoride ether complex, ntxiv ethylene oxide ntawm 25-30 ℃ nyob rau hauv stirring, thiab kub yuav cia li nce mus rau 38-45 ℃ tom qab dhau.Neutralize cov tshuaj tiv thaiv tau nrog poov tshuaj hydrocayanide methanol tov rau ph = 8-9chemicalbook.Rov qab kho methanol, distilled, thiab sau cov feem ua ntej 130 ℃ kom tau cov khoom nyoos.Tom qab ntawd fractionate thiab sau cov 123-125 ℃ feem, uas yog cov khoom tiav.Hauv kev tsim khoom lag luam, ethylene oxide thiab anhydrous methanol tau hnov mob ntawm qhov kub thiab txias, thiab cov khoom lag luam siab tuaj yeem tau txais yam tsis muaj catalysts.
Daim ntawv thov
1.Nws yog siv los ua ib txheej txheej hnyav, penetrant, leveling agent thiab organic synthesis intermediate, thiab kuj yog ib qho additive rau dav hlau roj.
2.2-methoxyethanol, tseem hu ua ethylene glyhat, yog cov kev cuam tshuam hauv qab tshuaj tua kab, me me ntawm Nitrocellulose thiab cov hluavtaws resin.
3.Cov khoom no yog siv los ua ib qho hnyav rau ntau yam roj, lignin, nitrocellulose, cellulose acetate, cawv soluble dyes thiab hluavtaws resins;Chemicalbook, ib tug reagent rau kev txiav txim ntawm hlau, sulfate thiab carbon disulfide, thiab ib tug nyias txheej rau txheej, yog siv nyob rau hauv lub ntim thiab sealing ntawm cellophane, ceev kom qhuav kua roj vanish thiab enamel.Nws kuj tseem siv tau los ua tus neeg nkag siab thiab qib tus neeg sawv cev hauv kev lag luam dye, lossis ua plasticizer thiab brightener.
4.Kev txiav txim siab ntawm hlau;Sulfate thiab carbon disulfide reagents, siv ntau yam roj;Lignin;Nitrocellulose;Cellulose acetate;Solvents rau cawv soluble dyes thiab hluavtaws resins.
