2. Insoluble hauv dej, soluble hauv organic solvents xws li ethanol, ether, thiab lwm yam.
3. Cov compound muaj kev ruaj ntseg siab thiab tsis yooj yim rau decompose ntawm chav tsev kub.
Nws lub hom phiaj:
1. 2-(trifluoromethoxy) benzyl bromide tuaj yeem siv los ua qhov nruab nrab rau kev sib txuas ntawm qee yam tshuaj, xws li tshuaj tua kab mob, tshuaj tua kab mob, thiab lwm yam.
2. Nws kuj yog siv rau cov synthesis ntawm cov tshuaj tua kab thiab kev npaj ntawm surfactants.
Txoj kev:
2-(trifluoromethoxy) benzyl bromide feem ntau yog tau los ntawm reacting benzyl bromide nrog trifluoromethanol. Cov txheej txheem tshuaj tiv thaiv yuav tsum tau siv cov tshuaj muaj zog alkaline thiab cov kuab tshuaj tsim nyog.
Cov ntaub ntawv kev nyab xeeb:
1. Cov khoom sib xyaw ua ke yog cov organic bromide, uas yuav ua rau tib neeg lub cev puas tsuaj, muaj kev khaus khaus thiab toxicity, thiab yuav tsum tsis txhob sib cuag nrog cov khoom rhiab xws li tawv nqaij, qhov muag, thiab ua pa.
2. Thaum lub sijhawm ua haujlwm, cov khoom siv tiv thaiv tus kheej, xws li cov hnab looj tes tiv thaiv, tsom iav thiab lub qhov ncauj qhov ntswg, yuav tsum muaj.
3. Thaum lub sij hawm cia thiab siv, kom deb ntawm qhov qhib nplaim taws thiab kub siab, thiab tsis txhob kov cov oxidants.
4. Lub compound yuav tsum tau ua raws li cov kev cai thiab cov kev cai nyob rau hauv cov txheej txheem ntawm kev kho cov khib nyiab kom tsis txhob muaj kuab paug ib puag ncig.
