Puas yog ethyl acetate chemical ib chav kawm 3 hnyav?

Puas yog ethyl acetate chemical ib chav kawm 3 hnyav?

Raws li ICH (International Council for Harmonisation) cov lus qhia ntawm cov tshuaj impurities, ethyl acetate yog categorized li Class 3 hnyav.

Chav kawm 3 cov kuab tshuaj yog txhais tau tias yog cov uas muaj peev xwm tsis muaj tshuaj lom, muaj kev tso cai rau txhua hnub (PDE) ntawm 50 mg lossis siab dua ib hnub.

Qhov kev faib tawm no txhais tau hais tias ethyl acetate nyob rau hauv cov kuab tshuaj lom tsawg tshaj plaws uas siv hauv kev tsim tshuaj lag luam- ua rau muaj kev pheej hmoo tsawg rau tib neeg kev noj qab haus huv thaum raug tshwm sim ntawm cov qib raug.

ethyl acetate hnyav (CAS 141 78 6) siv rau dab tsi?

Tom ntej: Ethyl Acetate CAS 141-78-6yog cov kuab tshuaj siv dav nrog ntau yam kev siv thoob plaws ntau qhov kev lag luam vim nws cov kuab tshuaj zoo heev, tsis muaj tshuaj lom, thiab pom zoo tsw.

1. Ethyl acetate (EtOAc) yog ua haujlwm los ua tus neeg sawv cev vim nws cov qab zib, fruity essence uas txhim khu cov aroma thiab saj ntawm cov khoom noj.

2. Hauv kev lag luam kws tshuaj, Ethyl Acetate (EtOAc) yog siv rau hauv kev rho tawm thiab ntxuav cov tshuaj tua kab mob, qee cov vitamins, thiab lwm yam tshuaj muaj txiaj ntsig (APIs).

3. Ethyl acetate qhov me me thiab qab ntxiag tsw ua rau nws haum rau kev siv tshuaj pleev ib ce, xws li: ntsia thawv polish remover, perfumes thiab fragrances, khoom tu plaub hau.

4. Nws ceev evaporation tus nqi thiab solvency zog ua ethyl acetate zoo tagnrho rau siv nyob rau hauv: xim thiab varnishes, nplaum, number case, luam ntawv.
