Ethyl acetoacetate yog cov kua tsis muaj kob uas muaj ntxhiab tsw ntxhiab tsw. Nws yog yooj yim soluble hauv ethanol, Ethyl Ehter, propylene glycol thiab ethyl acetate, thiab soluble hauv dej li 1:12.
Nws yog tsuas yog siv nyob rau hauv cov tshuaj, dyestuff, tshuaj tua kab thiab lwm yam. Nws tseem siv nyob rau hauv cov zaub mov ntxiv thiab flavors thiab tsw qab.
1. Cov khoom siv hluav taws xob organic: nws tau siv dav siv raws li lub tsev thaiv cov organic rau cov sib xyaw ua ke suav nrog cov khoom sib xyaw, agnismicals thiab dyes.
2. Flowing: Ethyl acetoacetate yog siv los ua cov tsw qab hauv cov zaub mov thiab dej haus vim nws cov txiv ntoo arluity.
3. Txuj lom: Nws tseem siv nyob rau hauv kev npaj ntawm cov tshuaj tsw qab thiab txuj lom.
4. Hnyav: Ethyl acetoacetate tuaj yeem ua raws li cov kuab tshuaj nyob rau ntau cov txheej txheem tshuaj thiab cov qauv.
5. Kev siv tshuaj lom neeg nruab nrab: Nws yog siv nyob rau hauv cov ntaub ntawv ntawm lwm yam tshuaj, xws li 1,3-dicarbonyl sib txuas, thiab hauv kev tawm tsam xws li claisen condensation.
6. Polymer tsim tawm: tuaj yeem siv los tsim qee cov polymers thiab resins.
Ruaj khov. Tsis sib haum nrog cov kua qaub, hauv paus, oxidizing cov neeg sawv cev, txo cov neeg sawv cev, cov hlau alkali. Combicible.
1 kg / hnab los yog 25 kg / nruas lossis 50 kg / nruas lossis raws li cov neeg siv khoom yuav tsum tau ua.

Khaws cia rau hauv lub tsev rau khoom txias thiab muaj cua rau hauv hluav taws, deb ntawm hluav taws thiab cov khoom cua sov;
Cais khaws nrog oxidants, txo cov neeg sawv cev, acids, alkali, zam kev sib xyaw.
1. Thawv: Siv cov thawv dav hlau ua los ntawm cov iav lossis siv tau cov yas kom tiv thaiv kom tsis txhob muaj paug thiab evaporation.
2. Kub: Khaws rau hauv qhov chaw txias thiab qhuav, kom deb ntawm kev tshav ntuj ncaj qha thiab cov khoom kub. Yog tias yuav tsum tau siv sijhawm ntev, nws yog qhov zoo tshaj los khaws nws ntawm chav tsev kub lossis hauv lub tub yees.
3. Qhov cua: ua kom cov chaw cia tau yog qhov cua kom tsis txhob muaj vapor perpectulation.
4. Daim ntawv lo: daim ntawv lo kom meej rau cov ntawv ntim nrog cov khoom siv tshuaj, kev xav, thiab cov ntaub ntawv kev phom sij.
5. Tsis zoo: Khaws deb ntawm cov muaj zog oxidants, acids thiab bases thaum lawv yuav hnov mob nrog Ethyl acetoacetate.
6. Kev ceev faj kev nyab xeeb: Khw raws li cov kev cai lij choj hauv zos thiab ua kom cov cuab yeej kev nyab xeeb muaj nyob rau hauv cov ntaub ntawv ntawm nchuav lossis txeej.
1. Ntim: Siv ntim khoom haum rau Ethyl acetoacetate. Nco ntsoov tias lub thawv ntim kaw kom nruj kom tiv thaiv tsis taus thiab evaporation.
2. Daim Ntawv Sau Npe: Sau npe kom meej rau txhua lub thawv nrog lub npe tshuaj lom neeg, cov cim kev phom sij thiab cov ntaub ntawv kev nyab xeeb. Qhov no suav nrog kev qhia tias nws yog cov kua hluav taws.
3. Kev thauj mus los ntawm cov cai thauj neeg: Ua raws li hauv zos, cov kev cai thoob teb chaws thiab thoob ntiaj teb rau kev thauj mus los ntawm cov khoom txaus ntshai. Qhov no suav nrog kev siv cov tsheb tshwj xeeb, cov kev thiab cov ntaub ntawv.
4. Kev tswj qhov kub: thaum lub sijhawm thauj mus los, thov khaws cov khoom kom deb ntawm huab cua sov thiab lub hnub ci ncaj qha. Nws yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav.
5. Zam kev sib xyaw: Tsis txhob thauj Ethyl acetoacetate ua ke nrog cov ntaub ntawv tsis sib xws (xws li oxidizers muaj zog lossis acids) los tiv thaiv kev phom sij.
6. Cov cuab yeej tiv thaiv tus kheej (PPE): Xyuas kom cov neeg ua haujlwm kov cov neeg thauj khoom tsim nyog ppe xws li hnab looj tes uas tsim nyog ppe xws li hnab looj tes tsim nyog thiab cov khaub ncaws tiv thaiv.
7. Cov txheej txheem thaum muaj xwm ceev: Thaum muaj tej yam nchuav lossis txeej thaum thauj khoom, tsim cov kev pab kub ceev. Qhov no suav nrog kev muaj cov khoom siv spill thiab cov khoom siv ua ntej npaj.
8. Kev kawm: Xyuas kom txhua tus neeg ua haujlwm koom nrog kev coj mus thaiv cov ntaub ntawv thiab paub txog cov kev pheej hmoo cuam tshuam nrog Ethyl acetoacetate.
