Daim ntawv thov
1. p-Toluoyl chloride yog dav siv los ua ib qho reagent nyob rau hauv cov organic synthesis los qhia cov p-toluoyl pab pawg rau hauv cov hom phiaj molecules, txhawb kev tsim cov tshuaj thiab tshuaj tshwj xeeb.
2. Cov khoom sib xyaw ua haujlwm ua haujlwm tseem ceeb hauv cov khoom siv hluav taws xob polymer rau kev sib txuas tshwj xeeb polymers nrog cov khoom tsim nyog rau kev siv tshwj xeeb.
3. p-Toluoyl chloride CAS 874-60-2 yog ua hauj lwm nyob rau hauv lub synthesis ntawm agrochemicals, nrog rau ib tug soj ntsuam anthelmintic compound kawm rau nws cov kev ua tau zoo tiv thaiv kab mob plab hnyuv kab mob.
Cia thiab ceev faj
1. Khaws p-Toluoyl chloride nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert gas (argon filling) nyob rau hauv ib tug txias, qhuav qhov chaw ntawm txias txias (2-8 degree), tiv thaiv los ntawm lub teeb thiab noo noo.
2. Khaws p-Toluoyl chloride CAS 874-}60-2 nruj me ntsis kom deb ntawm cov oxidizing muaj zog, cov hauv paus, cawv, amines, thiab hlau, vim p-Toluoyl chloride yog incompatible thiab reacts hnyav nrog dej thiab ya raws.
3. Kov p-Toluoyl chloride siv cov cuab yeej tiv thaiv tus kheej tsim nyog nrog rau cov tsom iav kom nruj, daim npog ntsej muag, tshuaj lom neeg- hnab looj tes tiv thaiv, thiab hauv lub hood kom tsis txhob ua pa tawm.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab muaj p-Toluoyl chloride siv cov khoom nqus dej qhuav (xws li xuab zeb), tiv thaiv kev sib cuag nrog dej.
2. Sau cov dej nchuav p-Toluoyl chloride CAS 874-60-2 siv lub tshuab nqus tsev tiv thaiv hluav taws xob lossis los ntawm kev txhuam ntub dej rau hauv cov ntim ntim, sau cov tshuaj tiv thaiv corrosion rau pov tseg raws li cov cai hauv zos.
3. Cov neeg ua haujlwm tu p-Toluoyl chloride spills yuav tsum hnav cov khoom tiv thaiv tag nrho nrog rau tus kheej- muaj cov cuab yeej ua pa thiab tiv thaiv kev nkag mus rau hauv cov qhov dej los yog cov dej.
Cov ntaub ntawv kev nyab xeeb
1. p-Toluoyl chloride yog corrosive, ua rau tawv nqaij kub hnyiab thiab qhov muag loj (H314, H318), nrog rau NFPA kev ntsuam xyuas kev noj qab haus huv ntawm 3 (kev phom sij loj).
2. p-Toluoyl chloride CAS 874-60-2 yog cov kua hluav taws xob hluav taws xob (flash point 82 degree) thiab reacts nrog dej, tso corrosive hydrogen chloride gas; thermal decomposition ua rau cov pa phem xws li carbon oxides thiab hydrogen chloride.
3. p-Toluoyl chloride yog cais rau kev thauj mus los ua kua corrosive (UN 3265, Hazard Class 8, Packing Group II) thiab yog siv rau kev tshawb fawb nkaus xwb, tsis yog siv rau tib neeg lossis kws kho tsiaj.
