Cov khoom ntawm methyl ethanoate (CAS 79-20-9) yog dab tsi?

Dab tsi yog cov khoom ntawm methyl ethanoate?

Methyl Ethanoate (CAS 79-20-9) muaj qhov hnyav ntawm 74.08 g / mol, qhov kub ntawm 57.1 degree, melting point ntawm -98 degree, thiab qhov ceev ntawm 0.932 g / cm³ ntawm 20 degree. Nws yog volatile heev thiab yooj yim soluble nyob rau hauv feem ntau cov organic solvents (xws li, ethanol, diethyl ether), thaum me ntsis soluble nyob rau hauv dej (solubility kwv yees li 25 g / L ntawm 20 degree). Vim muaj cov pab pawg ester hauv nws cov qauv molecular, nws nthuav tawm cov khoom siv tshuaj lom neeg thiab tuaj yeem ua rau hydrolysis, alcoholysis, thiab ammonolysis cov tshuaj tiv thaiv.

Methyl Ethanoate Solvent siv

Methyl Ethanoate ua haujlwm zoo ib puag ncig rau lwm cov kuab tshuaj ib txwm muaj (xws li acetone, methyl ethyl ketone) vim nws tsis tshua muaj toxicity, tsawg residue, thiab solubility zoo heev. Nws yog dav siv nyob rau hauv zus tau tej cov xim, inks, thiab adhesives, zoo dissolving polymers zoo li nitrocellulose thiab cellulose acetate. Hauv kev tsim khoom siv hluav taws xob, nws ntxuav lub rooj tsav xwm hluav taws xob thiab cov khoom siv kho qhov muag yam tsis muaj qhov seem seem thaum evaporation.

Chemical Intermediates
Raws li cov khoom siv tshuaj lom neeg tseem ceeb, methyl acetate synthesizes derivatives xws li acetamide thiab ethyl acetate. Piv txwv li, nws reacts nrog ammonia los tsim acetamide (ib qho tshuaj thiab tshuaj tua kab nruab nrab) thiab ua rau cov transesterification los tsim ethyl acetate -cov kuab tshuaj ntau dua.

Pharmaceutical thiab Food Industries
Hauv kev tsim tshuaj, Methyl Ethanoate ua haujlwm raws li cov kuab tshuaj tshem tawm lossis cov tshuaj tiv thaiv nruab nrab, tshwj xeeb tshaj yog tsim nyog rau kev rho tawm cov cua sov- cov khoom ntuj tsim. Hauv kev lag luam zaub mov, nws ua haujlwm raws li tus neeg sawv cev flavoring (ua raws li cov qauv kev nyab xeeb khoom noj), muab cov txiv hmab txiv ntoo aromas rau cov khoom qab zib thiab dej haus.

Kev siv zog tshiab thiab ib puag ncig
Methyl Ethanoate tuaj yeem txhim kho qhov qis -kub ntws ntawm biodiesel ua ib qho ntxiv. Tsis tas li ntawd, nws cov khoom degradation yog acetic acid thiab methanol, ua rau nws zoo ib puag ncig ntau dua li halogenated hydrocarbon cov kuab tshuaj thiab ua raws li cov tshuaj ntsuab ntsuab.

Dab tsi yog qhov chaw cia rau methyl ethanoate (CAS 79-20-9)?

Txawm hais tias methyl ethanoate muaj toxicity tsawg (qhov ncauj LD₅₀ hauv cov nas kwv yees li 5 g / kg), siab -cov pa paug tuaj yeem ua rau khaus qhov muag thiab ua pa. Kev raug ncua ntev yuav ua rau muaj kev nyuaj siab hauv nruab nrab paj hlwb.
Hnav cov iav tiv thaiv thaum tuav thiab xyuas kom muaj cua txaus. Khaws ntim rau hauv qhov chaw txias, tsaus, kom deb ntawm oxidizers, muaj zog acids, thiab cov hauv paus muaj zog. Nyob rau hauv cov ntaub ntawv ntawm to, siv xuab zeb los yog inert absorbent rau ntxuav; tsis txhob yaug ncaj qha nrog dej.
