Taw qhia
Nws yog ib qho organic compound nrog cov tshuaj formula C7H6FIS. Nws cov tsos yog xim tsis muaj xim rau daj ntseg daj kua nrog ib tug ntev-ntev thiab tshwj xeeb tsw.
Cov tshuaj no feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv los npaj lwm yam khoom siv organic, xws li tshuaj tua kab, tshuaj thiab dyes. Nws kuj tseem siv tau los ua tus neeg sawv cev complexing, hnyav thiab surfactant.
Txoj kev npaj ntawm halogen tuaj yeem tau txais los ntawm cov kauj ruam hauv qab no: Ua ntej, 2-methylbenzoic acid yog reacted nrog oxidizing tus neeg sawv cev thionyl chloride los tsim 2-methylbenzoic acid chloride. Cov kua qaub chloride yog tom qab ntawd ua haujlwm nrog barium iodide kom muab 2-iodo-5-methylbenzoic acid. Thaum kawg, 2-iodo-5-methylbenzoic acid tau hloov mus rau phosphonium los ntawm cov tshuaj tiv thaiv nrog nyiaj fluoride.
Thaum siv, xyuam xim rau nws txoj kev nyab xeeb. Nws yog cov kua dej uas muaj cov nplaim taws thiab yuav tsum tau khaws cia thiab siv kom tsis txhob muaj hluav taws kub thiab kub. Nws muaj cov nyhuv stimulating ntawm daim tawv nqaij thiab ob lub qhov muag, tsis txhob sib cuag. Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes thiab tsom iav thaum ua haujlwm. Raws li nrog rau lwm yam tshuaj, lawv yuav tsum tau siv nyob rau hauv ib tug zoo-ventilated cheeb tsam thiab ua raws li cov txheej txheem kuaj kom raug. Nyob rau hauv rooj plaub ntawm kev nqus, noj, lossis kev sib cuag ntawm daim tawv nqaij, nrhiav kev pab kho mob tam sim ntawd.
