Taw qhia
Xwm:
1. Nws yog dawb crystalline khoom uas tsis yog-volatile ntawm chav tsev kub.
2. Nws muaj ntsim cyanide tsw thiab yooj yim soluble hauv ethanol, chloroform, thiab acetonitrile.
Kev siv:
1. Nws yog ib qho tseem ceeb ntawm cov organic synthesis nruab nrab nrog kev siv dav hauv thaj chaw dyes thiab lwm yam tshuaj organic.
2. Nws tuaj yeem siv los ua cov khoom sib txuas xws li tshuaj tua kab mob, dyes, thiab roj hmab preservatives.
Txoj kev:
Cov txheej txheem synthesis ntawm 2-chlorobenzonitrile feem ntau yog tau los ntawm reacting chlorobenzene nrog sodium cyanide. Ua ntej, nyob rau hauv alkaline tej yam kev mob, chlorobenzene reacts nrog sodium cyanide los tsim chlorophenylcyanide, uas yog ces hydrolyzed kom tau 2-chlorobenzonitrile.
Kev ruaj ntseg:
1. Muaj qee yam toxicity. Kev sib cuag lossis nqus pa tuaj yeem ua rau qhov muag thiab tawv nqaij khaus, thiab txawm tias puas tsuaj.
2. Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog thaum lub sijhawm ua haujlwm kom tsis txhob sib cuag nrog daim tawv nqaij thiab ua pa.
3. Thaum lub sij hawm tuav, yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb kom tsis txhob muaj xwm txheej.
