Taw qhia
Nws yog cov organic compound nrog cov tshuaj formula C7H5Cl2F thiab molecular hnyav ntawm 177.02g / mol. Nws yog xim tsis muaj xim rau daj ntseg daj kua nrog ib tug pungent tsw.
Nws feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv los ua ke rau lwm cov organic tebchaw uas muaj cov qauv benzyl chloride, xws li kev npaj tshuaj, tshuaj tua kab thiab dyes. Nws tseem tuaj yeem siv ua tshuaj tua kab mob thiab tshuaj tua kab mob.
Cov compound tuaj yeem tsim los ntawm kev ua haujlwm benzyl fluoride nrog hydrogen chloride. Ua ntej, benzyl fluoride thiab hydrogen chloride react nyob rau hauv tej yam kev mob los tsim 4-chlorobenzyl hydrochloride, uas reacts nrog cuprous chloride los tsim phosphonium.
Thaum siv cov tshuaj lom, yuav tsum tau them nyiaj rau nws toxicity thiab irritation. Nws tuaj yeem ua rau khaus thiab puas rau ntawm daim tawv nqaij, qhov muag thiab ua pa. Kev tiv thaiv yuav tsum tau ua thaum lub sijhawm ua haujlwm, xws li hnav cov hnab looj tes tiv thaiv, tsom iav thiab lub ntsej muag tiv thaiv. Nyob rau tib lub sijhawm, nws yuav tsum nyob deb ntawm qhov hluav taws kub thiab oxidant, tsis txhob sib cuag nrog cov nplaim taws qhib. Thaum lub sijhawm khaws cia thiab thauj mus los, nws yuav tsum tsis txhob cuam tshuam nrog huab cua, noo noo thiab dej. Muab pov tseg kom raug thiab ua raws li cov txheej txheem kev nyab xeeb.
