Taw qhia
Mercury benzoate yog cov organic mercury compound nrog cov tshuaj formula C14H10HgO4. Nws yog cov xim tsis muaj xim crystalline uas ruaj khov ntawm chav tsev kub.
Ib qho ntawm cov kev siv tseem ceeb ntawm mercury benzoate yog ib qho catalyst rau organic synthesis. Nws tuaj yeem siv los ua cov organic sib txuas xws li cawv, ketones, acids, thiab lwm yam. Tsis tas li ntawd, mercury benzoate tuaj yeem siv rau hauv electroplating, fluorescents, fungicides, thiab lwm yam.
Txoj kev npaj ntawm mercury benzoate feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm benzoic acid thiab mercury hypochlorite (HgOCl). Cov kev sib npaug hauv qab no tuaj yeem raug xa mus rau hauv cov txheej txheem npaj tshwj xeeb:
C6H5CH2COOH + HgOCl → C6H5HgO2 + HCl + H2O
Ua tib zoo saib xyuas kev nyab xeeb thaum siv mercury benzoate. Nws yog ib qho tshuaj lom neeg uas tuaj yeem ua rau muaj kev phom sij loj rau tib neeg kev noj qab haus huv yog tias nqus tau los yog sib cuag ntawm daim tawv nqaij. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab cov ntaub thaiv npog ntsej muag yuav tsum tau hnav thaum siv thiab ua haujlwm hauv qhov chaw ua haujlwm zoo. Thaum khaws cia thiab thauj, kev sib cuag nrog cov kua qaub, oxides thiab lwm yam khoom yuav tsum raug zam kom tsis txhob muaj kev phom sij txaus ntshai. Kev pov tseg pov tseg yuav tsum tau ua raws li cov cai muaj feem xyuam. Tsis muaj qhov xwm txheej yuav tsum tau mercury benzoate tuaj rau hauv kev sib cuag nrog tib neeg lossis ib puag ncig.
