3,5-Dinitrobenzoyl Chloride (CAS # 99-33-2)
Xwm
daj muaju. Crystallization hauv benzene, flammable. Soluble nyob rau hauv ether, yuav ua tau dej thiab cawv decomposition, los yog nyob rau hauv cov av noo hydrolysis ntawm dinitrobenzoic acid thiab hydrochloric acid, yuav yaj nyob rau hauv non-hydroxy hnyav yam tsis muaj decomposition. Melting point 69.7 ° C. Boiling Point (1. 6kPa) 196 ℃.
Txoj Kev Npaj
benzoic acid yog nitrated nrog tov kua qaub (nitric acid thiab sulfuric acid) kom tau 3, 5-nitrobenzoic acid, uas yog ces acylated nrog thionyl chloride thiab chlorine, cov tshuaj tiv thaiv yog purified kom tau ib yam khoom (HCl roj tau tawm los ntawm cov tshuaj tiv thaiv. thiab absorbed nrog dej).
Siv
ib qho nruab nrab ntawm vitamin D kuj tseem siv tau los ua Disinfection preservative thiab reagent.
Kev nyab xeeb
siab toxicity, muaj zog irritation rau mucosa, daim tawv nqaij thiab cov ntaub so ntswg. Microsomal sudden variation test-Salmonella typhimurium 1 × 10 -6 m01 / phaj. Kev tsim cov hydrazide). Cov dej yuav tsum tau tiv thaiv, thiab tus neeg teb xov tooj yuav tsum hnav cov khoom tiv thaiv.sealed hauv iav fwj, nrog cov thawv ntoo. Cov khoom siv hluav taws xob thiab tshuaj lom yuav tsum tau khaws cia thiab thauj raws li cov cai. Saib xyuas kom tsis txhob muaj kev puas tsuaj.
