Cov tshuaj lom methyl acetate 79 20 9 cas?

Methyl acetate (CAS 79-20-9), tseem hu ua acetic acid methyl ester, yog siv dav siv cov organic hnyav hauv txheej, nplaum, inks, tshuaj ntxuav, thiab tshuaj synthesis. Thaum nws suav hais tias muaj kev phom sij me ntsis, kev nkag siab txog nws cov tshuaj lom thiab kev nyab xeeb yog qhov tseem ceeb rau kev lag luam, chav kuaj, thiab kev lag luam.

Methyl Acetate toxicity

Methyl acetate yog cov organic hnyav uas siv dav hauv kev tsim khoom. Nws cov yam ntxwv muaj kev phom sij tseem ceeb suav nrog cov nplaim hluav taws thiab tsis muaj hluav taws xob, muab faib ua cov kua hluav taws xob Class III. Cov khoom zoo li no muaj cov ntsiab lus qis qis thiab tuaj yeem tawg tau yooj yim thaum raug cov nplaim taws qhib lossis kub siab. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov cua thiab kev tiv thaiv hluav taws thaum siv.

Methyl Acetate kev ceev faj txog kev nyab xeeb

Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE):

• Hnav hnab looj tes, looj tsom iav dub, thiab khaub ncaws tiv thaiv.
• Siv NIOSH- pom zoo ua pa ua pa yog tias qhov cua tsis txaus.

Engineering Controls:

• Xyuas kom muaj qhov cua kom zoo lossis cov pa hauv zos hauv chaw ua haujlwm.
• Cia kom deb ntawm cov nplaim taws, qhib nplaim taws, thiab qhov chaw kub.

Cov Lus Qhia Cia:

• Khaws cia rau hauv qhov txias, zoo- qhov cua qhov chaw hauv cov thawv kaw ntom ntom.
• Tsis txhob raug oxidizing tus neeg sawv cev thiab muaj zog acids.

Pov tseg & pov tseg:

• Siv inert absorbents (xws li, xuab zeb, vermiculite) rau nchuav.
• Pov tseg raws li cov cai hauv cheeb tsam ib puag ncig.

Cov ntaub ntawv ntxiv ntawm Methyl Acetate

• Reactivity: Decomposes raws li UV irradiation rau CO₂, H₂, thiab CO; reacts nrog thorium oxide ntawm qhov kub thiab txias los tsim acetone thiab lwm yam khoom.

Dab tsi yog kev lag luam siv methyl acetate (MeOAc) cas no 79 20 9?

• Organic Solvent: Vim nws zoo heev solubility, methyl acetate (MeOAc) yog dav siv los ua cov organic hnyav nyob rau hauv coatings, inks, adhesives, thiab cov tshuaj ntxuav.
• Resin thiab Txheej Ntau Lawm: Hauv kev tsim khoom thiab txheej txheej, MeOAc ua haujlwm tseem ceeb ntawm cov khoom siv uas txhim kho cov khoom zoo xws li txheej zaj duab xis hardness thiab abrasion tsis kam.
• Fragrance Manufacturing: Muaj ib qho txawv aroma, methyl acetate kuj ua hauj lwm nyob rau hauv cov khoom noj khoom haus thiab naj hoom industries raws li ib tug tshuaj tsw qab tivthaiv kom muab cov scents rau cov khoom.
• Chemical Synthesis: Tsis tas li ntawd, methyl acetate ua haujlwm ua haujlwm nruab nrab hauv kev tsim lwm yam tshuaj, suav nrog qee yam yas, tshuaj, thiab dyes.
• Extraction Agent: Hauv cov txheej txheem kev rho tawm cov tshuaj, methyl acetate (MeOAc) tuaj yeem siv los rho cov roj thiab lwm cov khoom siv sib txuas los ntawm cov khoom cog thiab tsiaj txhu.
