Methyl Acetate

Zouping Jinxing Chemical Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm methyl acetate hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk methyl acetate hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Fast- drying hnyav: Siv rau hauv cov coatings, inks, thiab adhesives los hloov acetone los yog ethyl acetate; Cov yam ntxwv los ntawm evaporation sai, tsis muaj ntxhiab tsw, thiab cov ntsiab lus VOC tsawg (txawm tias tseem muab faib ua VOC).
Solvent rau cellulose esters: Siv nyob rau hauv nitrocellulose lacquers thiab ntawv txheej.
Extraction agent: Siv los rho tawm cov organic acids thiab fragrances los ntawm aqueous daws; siv hauv cov txheej txheem tshuaj rau kev rho tawm Penicillin G thiab cov vitamins.
Organic synthesis: Siv rau hauv kev tsim cov methyl acetoacetate, methyl methacrylate (MMA) ntawm txoj kev tsis ncaj, thiab cov tshuaj tua kab nruab nrab.
Cov txheej txheem rov ua dua tshiab: Siv nyob rau hauv qhov kaw - voj methyl acetate cracking thiab distillation txheej txheem nyob rau hauv PVA ntau lawm units.

Esterification ntawm methanol thiab acetic acid (ib txwm): Catalyzed los ntawm concentrated sulfuric acid; Txawm li cas los xij, kev siv hluav taws xob siab tshwm sim vim qhov qis qis ntawm cov khoom lag luam thiab tsim ntau yam azeotropes.
Carbonylation txoj kev: Methanol + acetic acid + hydrogen (raws li ib tug byproduct ntawm acetic anhydride txoj kev) los yog ncaj qha methanol carbonylation (los ntawm cov txheej txheem BP / Chiyoda).
Byproduct ntawm polyvinyl cawv (PVA) ntau lawm: Methyl acetate yog ib tug loj byproduct thaum PVA yog tsim los ntawm methanol transesterification; muaj nyob rau hauv qhov ntau ntawm tus nqi qis, nws feem ntau yog tawg rov qab rau hauv acetic acid thiab methanol rau kev rov ua dua tshiab.

Cov khoom siv dav dav ntawm esters: Hydrolysis catalyzed los ntawm cov kua qaub lossis cov hauv paus yields acetic acid thiab methanol (vim methanol muaj qhov kub tsis tshua muaj kub, qhov sib npaug hloov mus rau sab xis; kev lag luam rov qab feem ntau siv cov tshuaj tua kab mob catalytic).
Ammonolysis: Reacts nrog NH₃ tsim acetamide thiab methanol.
Claisen condensation: Nyob rau hauv lub hauv paus muaj zog catalysis, nws ua rau nws tus kheej -condensation los tawm methyl acetoacetate (txawm hais tias nws cov reactivity qis dua li ntawm ethyl acetate; interestingly, txawm lub methyl pab pawg neeg muab tsawg steric hindrance, nws yog tsis tshua muaj rau enolate tsim ester? ethyl ester yog feem ntau industrially).
Stability: ruaj khov ntawm chav tsev kub; khaws cia rau hauv cov thawv kaw kom deb ntawm cov dej noo; undergoes hydrolysis thaum raug cov acids muaj zog los yog hauv paus ntawm qhov kub thiab txias.

Mob toxicity: Tsawg toxicity; Qhov ncauj LD₅₀ hauv nas ≈ 3700 mg/kg. Txawm li cas los xij, siab - concentration vapors muaj zog tshuaj loog, ua rau kiv taub hau, xeev siab, thiab mucous membrane irritation.
Qhov muag / Daim tawv nqaij: Cov kua ua kua ua rau lub qhov muag; vapors irritates lub ntsws; Kev sib cuag ntev ua rau tawv nqaij qhuav.
Flammability/Explosion: Explosive limits 3.1%–16% (v/v); vapors hnyav dua li huab cua thiab kis raws hauv av.
Kev tiv thaiv: tawg- pov thawj qhov cua, cov pa roj carbon monoxide, hnab looj tes nitrile; npog cov khoom nchuav nrog ua npuas ncauj lossis xuab zeb / av- tsis txhob ntws tawm nrog dej (txawm hais tias soluble hauv dej, nws evaporates sai heev).
Cia / Thauj: UN 1231, Chav Kawm 3, PG II; khaws cia rau hauv daim pam nitrogen lossis hauv cov tso tsheb hlau luam; kom deb ntawm alkalis, acids, thiab oxidizing tus neeg sawv cev.
