Siv:
-Trifluoromethoxy benzyl chloride yog ib qho tseem ceeb organic synthesis intermediate, uas yog dav siv nyob rau hauv cov synthesis ntawm tshuaj thiab tshuaj tua kab. Nws tuaj yeem siv los ua ke benzothiazole tebchaw, benzotriazole tebchaw, 4-piperidinol compounds, thiab lwm yam.
-Trifluoromethoxybenzyl chloride kuj yog siv los ua tshuaj reagent thiab catalyst.
Txoj Kev Npaj:
Txoj kev npaj ntawm trifluoromethoxy benzyl chloride feem ntau yog npaj los ntawm reacting trifluoromethanol nrog benzyl chloride. Cov kauj ruam tshwj xeeb suav nrog reacting trifluoromethanol thiab benzyl chloride nyob rau hauv lub xub ntiag ntawm barium chloride ntawm qhov kub thiab txias rau ib lub sij hawm, thiab ces distilling kom tau cov khoom.
Cov ntaub ntawv kev nyab xeeb:
-Trifluoromethoxybenzyl chloride yog cov organic chlorine compound, thiab yuav tsum tau them nyiaj rau nws qhov khaus ntawm daim tawv nqaij, qhov muag thiab ua pa. Siv cov cuab yeej tiv thaiv tsim nyog, suav nrog tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv.
-Tsis txhob nqus nws cov vapors lossis kov nws daim tawv nqaij. Nyob rau hauv rooj plaub ntawm kev sib chwv, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob sai.
- Khaws kom deb ntawm hluav taws thiab oxidant, tsis txhob kub siab thiab ncaj qha tshav ntuj.
