Yog lawm, ethyl ethanoate / ethyl acetate (CAS 141-78-6) yog cais raws li Class 3 residual solvent raws li ICH (International Council for Harmonisation) Q3C cov lus qhia thiab USP.
Cov kuab tshuaj Class 3 yog dab tsi?
Raws li ICH Q3C (Residual Solvents Guidance): Chav kawm 3 cov kuab tshuaj muaj tsawg- cov kuab tshuaj lom, suav tias muaj kev nyab xeeb dua, thiab tsim nyog rau kev siv tshuaj. Chav kawm 3 cov kuab tshuaj yog qhov zoo dua thaum cov concentrations siab dua li Chav Kawm 1 lossis Chav Kawm 2 cov kuab tshuaj, thiab thaum txo cov tshuaj toxicity yuav tsum tau thiab kev tswj nruj dua tsis tsim nyog piv rau Chav Kawm 1 (muaj tshuaj lom heev) lossis Chav Kawm 2 (tshuaj lom) cov kuab tshuaj.
CAS 141-78-6 Ethyl Acetate Solvent Classification
- ICH Q3C Kev faib tawm:Chav kawm 3
- Tso cai pom txhua hnub (PDE):50 mg / hnub (cov lus qhia ib txwm)
- Toxicity:Tsawg; feem ntau muaj kev nyab xeeb hauv kev tswj kom muaj nuj nqis
Ethyl acetate yog dav siv los ua cov kuab tshuaj residual hauv kev tsim tshuaj thiab zaub mov- qib kev siv.
Vim li cas Ethyl Acetate Classified li Class 3 Solvent?
Vim tias nws muaj cov tshuaj toxicity tsawg, qhov kub nruab nrab, thiab tau yooj yim tshem tawm thaum lub sij hawm tsim khoom, ethyl acetate (CAS No. 141-78-6) tau muab faib ua Class 3 hnyav raws li ICH Q3C.
1. Tsawg toxicity
Ethyl acetate muaj qhov tsis tshua muaj mob hnyav thiab mob toxicity piv nrog ntau cov kuab tshuaj. Thaum kho kom raug, nws muaj kev pheej hmoo rau kev noj qab haus huv tsawg hauv kev ua tshuaj.
2. Kev tshem tawm tau zoo thaum tsim khoom
Nrog rau qhov kub siab ntawm kwv yees li 77 degree, ethyl acetate evaporates yooj yim thaum ziab thiab hnyav rov ua haujlwm. Qhov no ua rau nws yooj yim dua los txo cov kuab tshuaj seem hauv cov khoom siv tshuaj tiav.
Daim ntawv thov ntawm Chav Kawm 3 Ethyl Acetate Solvent
1. Xim, Txheej, thiab Inks
Kev lag luam loj tshaj plaws (tshwj xeeb hauv Asia). Ethyl acetate ua hauj lwm ceev ceev -evaporating hnyav nyob rau hauv cov xim, varnishes, thiab inks, ua kom qhuav sai thiab haum rau siab - ceev luam ntawv thiab tshuaj tsuag.
2. Adhesives thiab ntim
Siv rau hauv cov nplaum, sealants, thiab ntim tau yooj yim. Nws tuaj yeem ua rau cov nplaum muaj zog thiab ceev ceev - cov ntawv ziab kom qhuav rau ntim cov yeeb yaj kiab / foils.
3. Pharmaceuticals thiab Tshuaj pleev ib ce
Tus account rau kwv yees li 8-10% ntawm kev thov thoob ntiaj teb. Siv nyob rau hauv tshuaj purification; siv rau hauv kev saib xyuas ntsia thawv thiab naj hoom, yam ntxwv ntawm evaporation ceev.
4. Khoom noj khoom haus thiab dej haus
Siv rau caffeine thiab tsw extraction. Cov me me muaj kev nyab xeeb rau kev siv los ua cov txiv hmab txiv ntoo tsw.

Regulatory Status Thoob Ntiaj Teb
CAS 141-78-6 Ethyl acetate's Class 3 designation raug lees paub thoob plaws cov khw muag tshuaj loj.
Cov cai tswj hwm uas ua raws lossis siv ICH Q3C cov lus qhia suav nrog:
- Tebchaws Asmeskas (FDA)
- European Union (EMA)
- Nyiv (PMDA)
- United Kingdom (MHRA)
Ntau lub tebchaws tau txais cov qauv tshuaj ICH
Raws li qhov tshwm sim, cov chaw tsim tshuaj lag luam muab kev lag luam thoob ntiaj teb feem ntau siv ethyl acetate ua cov kuab tshuaj extraction, purification hnyav, recrystallization hnyav, lossis cov tshuaj tiv thaiv nruab nrab.
Puas yog kev faib ua "Class 3" txhais tau tias ethyl acetate muaj kev nyab xeeb kiag li?
Tsis yog. Ib qho kev xav tsis zoo yog qhov "Class 3" kev faib tawm txhais tau tias cov kuab tshuaj tsis muaj mob; qhov kev pom no tsis raug. "Class 3" tsuas yog qhia txog kev pheej hmoo toxicological tsawg; nws tsis qhia tias tsis muaj kev phom sij tag nrho.
Ethyl acetate cov kuab tshuaj tseem muaj hluav taws kub heev, tuaj yeem ua rau lub qhov muag khaus, tuaj yeem ua rau lub ntsws ua pa ntawm qhov muaj pa ntau, thiab ua rau muaj kev pheej hmoo yog tias ua haujlwm tsis zoo hauv qhov chaw tsis zoo.
Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li kev tswj hwm engineering tsim nyog, tawg- cov khoom pov thawj, cov cuab yeej tiv thaiv tus kheej (PPE), thiab kev tiv thaiv kev raug ua haujlwm raws li Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS) thiab cov cai hauv chaw ua haujlwm hauv zos.
