Taw qhia
Nitrobenzoyl chloride, tshuaj formula C6H4 (NO2) COCl, yog cov kua daj daj nrog cov ntxhiab tsw. Hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv ntawm nitrobenzoyl chloride:
Xwm:
1. Cov tsos mob: Nitrobenzoyl chloride yog cov kua daj daj.
2. tsw: tsw ntxhiab tsw.
3. solubility: soluble hauv organic solvents xws li ether thiab chlorinated hydrocarbons, me ntsis soluble hauv dej.
4. Kev ruaj ntseg: kuj ruaj khov ntawm chav tsev kub, tab sis yuav hnov mob hnyav nrog dej thiab kua qaub.
Siv:
1. Nitrobenzoyl chloride tuaj yeem siv los ua cov khoom siv raw rau cov organic synthesis thiab kev npaj ntawm lwm cov organic tebchaw.
2. tuaj yeem siv rau kev npaj cov fluorescent dyes, dye intermediates thiab lwm yam tshuaj.
3. Vim nws cov reactivity siab, nws tuaj yeem siv rau cov tshuaj tsw qab acyl chloride hloov pauv hauv cov organic synthesis.
Txoj Kev Npaj:
Kev npaj ntawm nitrobenzoyl chloride tuaj yeem tau los ntawm reacting nitrobenzoic acid nrog thionyl chloride hauv cov pa roj carbon tetrachloride, thiab tom qab ntawd ua kom huv cov tshuaj tiv thaiv los ntawm distillation.
Cov ntaub ntawv kev nyab xeeb:
1. Nitrobenzoyl chloride ua rau khaus thiab tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.
2. siv los hnav cov hnab looj tes tiv thaiv, tsom iav thiab cov tsho hauv chav kuaj thiab lwm yam khoom siv tiv thaiv.
3. yuav tsum tau ua nyob rau hauv ib qho chaw zoo-ventilated kom tsis txhob nqus ntawm nws vapor.
4. Tsis txhob ua phem rau cov dej, kua qaub, thiab lwm yam, uas tuaj yeem ua rau hluav taws kub lossis tawg.
5. Cov khib nyiab yuav tsum muab pov tseg raws li cov kev cai thiab cov cai thiab yuav tsum tsis txhob muab pov tseg rau hauv ib puag ncig raws li qhov xav tau.
