Taw qhia
Nws yog ib qho organic compound nrog cov tshuaj formula C5H5ClN2. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
Nws yog xim tsis muaj xim rau yellowish kua nrog ib tug tshwj xeeb tsw. Nws muaj qhov kub ntawm qhov kub thiab txias ntawm chav tsev kub. Nws yog soluble hauv cov kuab tshuaj organic xws li diethyl ether, acetone thiab dichloromethane.
Siv:
Nws yog ib qho tseem ceeb ntawm cov organic nruab nrab, uas tuaj yeem siv dav hauv kev sib xyaw ntawm cov tshuaj thiab tshuaj tua kab. Nws yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm ntau yam tshuaj xws li tshuaj tua kab mob thiab tshuaj tua kab mob. Tsis tas li ntawd, nws tseem tuaj yeem siv los npaj lwm cov organic sib txuas, xws li dyes thiab kev sib koom ua ke.
Txoj kev:
Txoj kev npaj ntawm calcium tuaj yeem tau los ntawm kev ua haujlwm 2-methyl pyrimidine nrog thionyl chloride. Cov kev mob tshwm sim tshwj xeeb tuaj yeem hloov kho raws li qhov xav tau ntawm kev sim, tab sis cov kev mob tshwm sim tau ua nyob rau hauv inert cua, chav tsev kub lossis cua sov.
Cov ntaub ntawv kev nyab xeeb:
Nws muaj toxicity tsawg raws li kev siv dav dav, tab sis kev tiv thaiv tsim nyog tseem yuav tsum tau ua. Thaum lub sijhawm ua haujlwm, kev sib cuag nrog daim tawv nqaij, qhov muag thiab nqus pa ntawm vapors yuav tsum raug zam, thiab cov tsom iav thiab hnab looj tes yuav tsum hnav yog tias tsim nyog. Yog tias koj tau ntsib nrog cov tshuaj no, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob. Nyob rau tib lub sijhawm, tsis txhob sib xyaw nrog cov oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj hluav taws kub lossis tawg. Kev khaws cia yuav tsum tau muab tso rau hauv qhov chaw qhuav, txias, zoo-ventilated, deb ntawm hluav taws thiab combustibles.
