3-bromo-2-chloro-6-picoline (CAS # 185017-72-5) Taw qhia
yog ib yam khoom uas muaj xim dawb mus rau yellowish. Nws cov ntsiab lus melting yog li 63-65 degrees Celsius thiab nws qhov ceev yog li 1.6g / cm³. Cov tshuaj no yog soluble hauv cov kuab tshuaj organic xws li cawv thiab ethers ntawm qhov kub thiab txias.
Siv:
Nws feem ntau yog siv los ua reagent thiab nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv los ua catalyst, oxidant thiab reductant rau kev sib txuas ntawm ntau hom organic tebchaw. Tsis tas li ntawd, nws tuaj yeem siv rau kev npaj cov khoom xyaw nquag thiab cov tshuaj tua kab mob hauv kev kho mob.
Txoj kev:
Nws tuaj yeem ua ke los ntawm ntau txoj hauv kev. Ib txoj hauv kev zoo tshaj plaws yog los ua cov tshuaj pyridine thiab bromoacetate, thiab tom qab ntawd hnov mob nrog tooj liab chloride kom tau txais cov khoom lag luam.
Cov ntaub ntawv kev nyab xeeb:
Thaum siv thiab tuav: Ua tib zoo saib xyuas cov teeb meem kev nyab xeeb hauv qab no:
-Qhov kev sib xyaw no muaj peev xwm ua rau khaus thiab ua rau cov kab mob ua pa, qhov muag thiab tawv nqaij, thiab kev sib cuag ncaj qha yuav tsum raug zam.
-hauv kev siv cov txheej txheem yuav tsum zam kom tsis txhob nqus cov plua plav lossis chav, qhov xav tau kom muaj cua zoo.
- Cov khoom siv tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv.
-Tsis txhob khaws lossis sib tov cov tshuaj no nrog cov oxidants muaj zog, muaj zog acids lossis cov hauv paus muaj zog kom tsis txhob muaj kev phom sij txaus ntshai.
-Thaum pov tseg cov khoom pov tseg, yuav tsum ua kom raug thiab muab pov tseg raws li cov cai hauv zos.
