Taw qhia
4-Amino-2-trifluoromethylbenzonitrile yog cov organic compound.
Solubility: Nws tuaj yeem yaj hauv qee cov kuab tshuaj organic (xws li ethanol, methylene chloride, thiab lwm yam).
Nws tuaj yeem siv los ua ib qho nruab nrab hauv kev sib txuas ntawm lwm cov organic tebchaw, siv rau hauv kev npaj ntawm glyphosate, chlorchlor thiab lwm yam tshuaj tua kab, thiab tseem tuaj yeem siv los ua ke qee qhov bioactive molecules.
Txoj kev npaj: Txoj kev npaj ntawm 4-amino-2-trifluoromethylbenzonitrile feem ntau tau los ntawm cov tshuaj tiv thaiv. Ib txoj kev npaj siv feem ntau yog synthesis los ntawm cyanidation cov tshuaj tiv thaiv, nyob rau hauv uas trifluoromethylbenzoic acid yog reacted nrog sodium cyanide, thiab tom qab ntawd undergoes ib tug txo cov tshuaj tiv thaiv kom tau cov hom phiaj cov khoom.
Cov ntaub ntawv kev nyab xeeb: 4-amino-2-trifluoromethylbenzonitrile yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thaum siv, xws li hnav hnab looj tes tiv thaiv thiab tsom iav. Tsis txhob nqus nws cov vapors lossis hmoov av, thiab kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Thaum khaws cia, nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav thiab qhov cua, kom deb ntawm oxidants thiab acids. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog kev noj, nrhiav kev kho mob tam sim ntawd. Thaum muab pov tseg, nws yuav tsum muab pov tseg raws li cov txheej txheem tau teev tseg los ntawm tsoomfwv hauv nroog.
