Txheej txheem cej luam ntawm kev phom sij

Kev phom sij rau lub cev thiab tshuaj lom neeg: muaj xim tsis muaj kob. Miscible nrog dej, cawv, ether, chloroform, benzene, ethyl acetate thiab carbon disulfide, thiab tsis zoo soluble hauv roj av ether. Nws yog ib qho tsis muaj xim polar hnyav nrog lub siab kub kub thiab tseem yog ib qho nruab nrab ntawm cov organic synthesis. Nws tuaj yeem tsim cov ntsev ntsev nrog alkali hlau, hlau oxides lossis alkaline hydroxides. Kev phom sij rau kev noj qab haus huv: Nws muaj qhov mob me me rau ntawm daim tawv nqaij, tab sis tsis pom qhov nqus tau. Vim qhov tsis tshua muaj vapor siab, qhov kev pheej hmoo ntawm kev nqus pa yog qhov tsawg heev. Txawm li cas los xij, kev cuam tshuam ntev tuaj yeem ua rau lub cev tsis ua haujlwm ntawm lub hauv nruab nrab paj hlwb thiab ua rau cov kab mob hauv lub ntsws, ob lub raum, thiab vascular systems.

Environmental hazards: Cov khoom no muaj kev puas tsuaj rau ib puag ncig, thiab yuav tsum tau saib xyuas tshwj xeeb rau cov dej thiab cov cua. GHS phom sij: Raws li "Txoj Cai Tswjfwm rau Kev faib tawm thiab kev sib txuas lus phom sij ntawm cov tshuaj" (GB13690-2009) thiab cov txheej txheem rau kev faib tshuaj lom neeg, cov ntawv ceeb toom thiab cov lus qhia ceeb toom, cov khoom no yog rau qhov muag puas / qhov muag loj. khaus khaus -2

Pom zoo siv ntawm cov khoom: siv raws li hnyav thiab organic synthesis intermediate. Siv los ua nylon -4 thiab vinyl pyrrolidone, thiab lwm yam. Feem ntau yog siv los ua cov kuab tshuaj rau cov khoom siv hluavtaws, tshuaj tua kab, polyols, inks, iodine, thiab lwm yam. Nws tuaj yeem siv los ua plasticizer rau acrylic thiab acrylic styrene resins, extractant rau aromatic tebchaw, ib tug decolorizer rau kerosene, rosin, fatty acids, thiab ib tug raw khoom rau kev npaj ntawm nylon-4, polyvinyl pyrrolidone, 4-aminobutyric acid thiab nws cov derivatives, thiab lwm yam.
