Taw qhia
2-Chlorobenzophenone. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
2-Chlorobenzophenone yog cov xim tsis muaj xim rau daj. Nws muaj pungent tsw, soluble nyob rau hauv organic solvents xws li ethanol thiab acetone, thiab yog insoluble nyob rau hauv dej. Nws yog ib qho tshuaj tsw qab ketone.
Siv:
2-Chlorobenzophenone muaj ntau yam kev siv hauv cov organic synthesis. Nws kuj tseem siv tau los ua cov khoom siv photosensitive thiab dye intermediate.
Txoj kev:
2-Chlorobenzophenone tuaj yeem npaj los ntawm Plaub-Gram cov tshuaj tiv thaiv ntawm iodobenzene. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv ib qho inert hnyav xws li methylene chloride los yog dichloroethane nyob rau hauv lub xub ntiag ntawm tooj liab chloride. Rau cov txheej txheem synthesis tshwj xeeb, thov xa mus rau cov phau ntawv qhia txog cov organic chemistry lossis cov ntaub ntawv tshaj lij.
Cov ntaub ntawv kev nyab xeeb:
Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum siv 2-chlorobenzobenzophenone. Nws yog ib qho khaus khaus uas yuav ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa. Cov looj tsom iav tiv thaiv, hnab looj tes, thiab cov cuab yeej tiv thaiv ua pa tsim nyog yuav tsum tau hnav. Tsis txhob sib cuag nrog daim tawv nqaij thiab xyuas kom meej siv nyob rau hauv ib qho chaw ventilated txaus. Yog tias nqus tau los yog nqos, nrhiav kev kho mob tam sim ntawd.
