1-Methoxy-2-propyl acetate Siv Thiab Synthesis

Kev piav qhia	Propylene glycol methyl ether acetate (PGMEA), tseem hu ua propylene glycol monomethyl ether acetate, nrog cov mis molecular ntawm C6H12O3, yog cov kua tsis muaj xim hygroscopic nrog cov ntxhiab tsw tshwj xeeb. Nws yog ib qho tsis muaj kuab lom nrog ntau pawg ua haujlwm. Nws yog tsuas yog siv los ua cov kuab tshuaj ntawm number case, xim, number case, textile dye thiab textile oil agent, thiab kuj ua tus neeg saib xyuas hauv kev tsim LCD. Flammable, tej zaum yuav ua rau tawg vapor / cua sib tov saum toj no 42 degree C. Propylene glycol methyl ether acetate (PGMEA) yog ib qho hnyav hnyav heev. Nws cov molecule muaj ob qho tib si ether bond thiab carbonyl. Carbonyl tsim cov qauv ntawm ester thiab muaj alkyl tib lub sijhawm. Nyob rau hauv tib lub molecule, muaj ob qho tib si tsis-polar thiab polar qhov chaw. Cov pab pawg ua haujlwm ntawm ob qhov chaw no tsis tsuas yog txwv thiab tawm tsam ib leeg xwb, tab sis kuj ua si lawv lub luag haujlwm tseem ceeb. Yog li ntawd, nws muaj qee yam solubility rau cov khoom tsis muaj polar thiab cov polar tshuaj. 1-Methoxy-2-propyl acetate (PGMEA) yog ib yam khoom uas muaj pawg polar thiab nonpolar pawg, muaj peev xwm ua kom yaj thiab sib txuas tau zoo, feem ntau yog siv rau hauv cov kuab tshuaj raws li txheej thiab tshuaj ntsuam luam ntawv number case. Siv dipropylene glycol methyl ether thiab acetic acid ua raw khoom, nyob rau hauv lub catalysis ntawm cov kua qaub, los ntawm esterification cov tshuaj tiv thaiv rau generated crude khoom thiab nws siab purity PGMEA tom qab distillation.
Chemical Properties	1-Methoxy-2-propyl acetate (Methoxypropyl Acetate) yog cov kua ntshiab, me ntsis hygroscopic nrog cov ntxhiab tsw me ntsis. Nws yog dawb do miscible nrog feem ntau cov organic solvents, tab sis tsuas yog txwv miscibility nrog dej. Los ntawm kev tsim txiaj ntawm nws cov ether thiab ester pawg, Methoxypropyl Acetate nkag mus rau hauv cov tshuaj tiv thaiv uas yog cov yam ntxwv ntawm ethers thiab esters thiab tso saib lawv lub zog hnyav. Piv txwv li, nws dissolves ntau yam ntuj thiab hluavtaws resins, waxes, rog thiab roj. Txij li thaum Methoxypropyl Acetate tuaj yeem hnov mob nrog cov pa hauv huab cua los tsim cov peroxides, BASF muab nws inhibited nrog 2.6-di-tert-butyl-para-cresol (butylated hydroxytoluene - BHT).
Siv	1,2-Propanediol monomethyl ether acetate yog siv los ua cov kuab tshuaj rau cov xim, inks, lacquers, varnishes, cleaners thiab coatings. Nws kuj yog siv los ua cov kuab tshuaj rau degreasing Circuit Court boards thiab hauv daim ntawv thov zaub mov. Tsis tas li ntawd, nws yog siv nyob rau hauv photoresist formulations nyob rau hauv semiconductor kev lag luam.
Daim ntawv thov	1-Methoxy-2-propyl acetate yog cov kuab tshuaj qib siab uas muaj tshuaj lom thiab ua haujlwm zoo heev. Nws muaj zog solubility rau polar thiab non-polar tshuaj. Nws yog tsim rau cov kuab tshuaj ntawm ntau yam polymers ntawm qib high-qib txheej thiab inks, xws li aminomethyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin thiab nitrocellulose. Ntawm lawv. Propylene glycol methyl ether propionate yog cov kuab tshuaj zoo tshaj plaws hauv cov tshuaj pleev xim thiab pleev xim. Nws yog tsim rau unsaturated polyester, polyurethane resin, acrylic resin, epoxy resin, thiab lwm yam.
Kev piav qhia dav dav	Propylene glycol monomethyl ether acetate (PGMEA) yog photoresist hnyav. Nws degradation los ntawm cov kab mob hauv cov av sib txawv tau raug tshawb xyuas. Tus nqi ntawm qhov ncauj siv tshuaj (RfD) ntawm PGMEA tau txais los ntawm kev tshawb fawb txog kev nqus pa. Solubility ntawm (5-alkylsulfonyloxyimino-5H-thiophen-2-ylidene)-2-methylphenyl-acetonitriles hauv PGMEA tau txheeb xyuas.
Flammability thiab Explosibility	Flamable
Kev ruaj ntseg Profile	Muaj tshuaj lom los ntawm txoj kev intraperitoneal. Me ntsis tshuaj lom los ntawm kev noj thiab kev sib cuag ntawm daim tawv nqaij. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating vapors.
