Lub cev nqaij daim tawv thiab tshuaj lom neeg ntawm ethyl 4-} chloroacetoacetate muaj:
Zog: pob tshab tsis muaj xim rau lub teeb daj ua kua nrog acetic acid tsw.
Qhov ceev faj: 1.2 ± {0. 1 g / cmhg, tab sis yuav tsawg li 103 degree nyob rau hauv siab.
Melting taw tes thiab nyem taw tes: Melting taw tes yog -8 degree, nyem taw tes yog li ntawm 96.7 degree.
Solubility: me ntsis soluble hauv dej (47.5 G / L, 20 degree), yooj yim soluble hauv cov kuab tshuaj organic.
Kev phom sij: Corrosive thiab lom, kev sib cuag yuav tsum tau tiv thaiv nruj heev, kev cia khoom yuav tsum nyob deb ntawm oxidants.
Daim Ntawv Thov Tshwj Xeeb
Raws li ib tug tseem ceeb kws tshuaj thiab tshuaj 50 theem nrab, nws cov chaw thov tseem ceeb muaj:
Kws Tshuaj Kho Mob: Nruab nrab siv nyob rau hauv synthesis ntawm cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob thiab cov tshuaj sib xyaw.
Cov tshuaj tua kab ntau heev: Koom nrog cov hluavtaws ntawm cov tshuaj tua kab thiab cov tshuaj tua kab, xws li qee cov chlorine-muaj cov tshuaj tua kab mob organiccephosphorus.
Zoo tshuaj lom: nws kuj muaj cov peev xwm siv nyob rau hauv dyes, tshuaj tsw qab thiab lwm thaj teb.
Kev npaj npaj thiab cov kauj ruam
Cov txheej txheem npaj npaj tam sim no siv cov tshuaj ethyl acetoacetate thiab sulfulyl chloride li cov ntaub ntawv raw. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Tsawg qhov cua kub hnyav: Cool Ethyl acetoacetate rau {{0 degree, maj mam ntxiv kub kom tswj cov kev tsis zoo.
Kev kho mob tom qab tshuaj tiv thaiv: Tom qab nplawm ntawm chav tsev kub rau 2 ~ 4 teev, kub rau 3585 degree kom tshem tawm cov generated so₂ thiab hcl roj.
Distillation rov qab: Rov qab siv tsis tau txog Ethyl acetoacetate los ntawm lub tshuab nqus tsev distillation ntawm 85 ~ 95 degree kom ua tiav cov khoom siv remycling.
Kho kom ua kom zoo nkauj: txias rau 30 degree kom tau txais cov khoom nyoos, thiab lub purity tuaj yeem ncav cuag 97% ~ 99% tom qab kev ua kom tiav ntxiv.
Cov ntsiab lus tseem ceeb: Cov tshuaj reactor yuav tsum tau nruab nrog qhov ntsuas cua sov (xws li cov khoom siv kub muab kua rau kom ntseeg tau tias muaj kev phom sij thiab kev nyab xeeb.
