Puas yog ethyl acetate ib qho hnyav (CAS 141 78 6)?

Puas yog ethyl acetate ib qho hnyav (CAS 141 78 6)?

Tom ntej: Ethyl Acetate CAS 141-78-6yog ib qho yooj yim heev thiab ntau yam organic hnyav.

Ethyl acetate (EtOAc) yog cov kua ntshiab, tsis muaj xim nrog lub qab ntxiag fruity tsw reminiscent ntawm ripe pears. Kev khav theeb cov khoom tseem ceeb uas ua rau nws tsis tuaj yeem cuam tshuam thoob plaws kev lag luam, nws muaj qhov kub ntawm 77.1 ° C, melting point ntawm -83.6 ° C, thiab siab volatility -ua kom ceev evaporation uas yog ib qho tseem ceeb rau lub sij hawm-sensitive txheej txheem. Nws pom zoo solubility zoo nyob rau hauv cov kuab tshuaj organic xws li ethanol, ether, thiab acetone, thaum me ntsis miscible nyob rau hauv dej, ua ke nrog ib tug flash point ntawm -4 ° C (kaw khob) uas faib nws raws li ib tug flammable kua uas yuav tsum tau cov qauv kev ruaj ntseg ceev faj.

Cov yam ntxwv zoo li no ua rauethyl acetate (CAS 141 78 6)ntau yam workhorse:

Nws yog dav siv los ua cov kuab tshuaj nyob rau hauv cov txheej txheem, xim, nplaum, thiab luam ntawv number case industries, qhov twg nws ceev ceev - ziab xwm thiab muaj zog solvency zog txhim kho cov khoom ua tau zoo thiab ntau lawm efficiency. Tsis tas li ntawd, nws cov tshuaj tsw qab me me, fruity aroma thiab toxicity tsawg tsim nyog nws ua tus neeg sawv cev muaj kev nyab xeeb hauv kev lag luam zaub mov, siv los ua cov ntawv sau txiv hmab txiv ntoo hauv cov khoom qab zib, dej haus, thiab cov khoom ci. Raws li ib qho tseem ceeb ester, ethyl acetate sawv ua ib qho ntawm cov tshuaj tseem ceeb tshaj plaws uas txhawb nqa ntau hom kev lag luam thoob ntiaj teb.

Puas yog ethyl acetate yog cov kuab tshuaj lom?

Ethyl acetate feem ntau suav hais tias yog ib qho qis - toxicity solvent txheeb ze rau ntau lwm yam.

Nws cov teeb meem tseem ceeb yog:

• Flammability (nws qhov kev pheej hmoo tseem ceeb tshaj plaws).
• Irritant: Nws tuaj yeem ua rau khaus qhov muag, ua pa, thiab tawv nqaij thaum raug.
• Narcotic Effects: Cov vapor concentrations tuaj yeem ua rau kiv taub hau, tsaug zog, thiab hauv nruab nrab lub paj hlwb kev nyuaj siab.

Nws "tsis muaj tshuaj lom" yog hais txog nws qhov tsis muaj kev noj qab haus huv ntev ntev - cov teebmeem kev noj qab haus huv thaum raug tswj tau, tab sis kev ua pa kom raug thiab cov cuab yeej tiv thaiv tus kheej (PPE) yog ib txwm xav tau.
