Taw qhia
METHYL 5,6-dichloronicotinate yog cov organic compound nrog cov tshuaj formula C7H5Cl2NO2. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
1. Cov tsos mob: METHYL 5,6-dichloronicotinate yog cov kua tsis muaj xim.
2. Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic feem ntau, xws li cawv, ethers, chlorinated hydrocarbons, thiab lwm yam.
3. Melting point thiab boiling point: Lub melting point ntawm METHYL 5,6-dichloronicotinate yog hais txog 68-71 degrees Celsius, thiab lub boiling point yog hais txog 175 degrees Celsius.
Siv:
1.METHYL 5,6-dichloronicotinate tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis thiab siv rau hauv kev sib txuas ntawm lwm cov organic tebchaw.
2. Nws kuj tuaj yeem siv rau hauv thaj chaw tshuaj tua kab, tshuaj thiab tshuaj pleev xim.
Txoj kev:
Cov txheej txheem synthesis ntawm METHYL 5,6-dichloronicotinate tuaj yeem ua tiav los ntawm cov kauj ruam hauv qab no:
1. Ua ntej, nicotinic acid (nicotinic acid) reacts nrog thionyl chloride (thionyl chloride) los tsim nicotinic acid chloride (nicotinoyl chloride).
2. Tom qab ntawd, nicotinic acid chloride reacted nrog methanol los tsim METHYL 5,6-dichloronicotinate.
Cov ntaub ntawv kev nyab xeeb:
1. METHYL 5,6-dichloronicotinate yog cov organic compound uas ua rau khaus. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag thaum siv lossis tiv tauj.
2. Thaum lub sijhawm ua haujlwm, nws yog ib qho tsim nyog los xyuas kom meej qhov cua zoo thiab tsis txhob nqus nws cov pa.
3. Thaum khaws cia thiab tuav, nws yuav tsum khaws cia kom deb ntawm hluav taws thiab oxidant.
4. Nyob rau hauv rooj plaub ntawm kev nqus pa los yog kev sib cuag, tam sim ntawd yaug qhov chaw cuam tshuam nrog dej txaus thiab nrhiav kev pab kho mob.
5. Thaum siv METHYL 5,6-dichloronicotinate, Thov ua raws li cov txheej txheem kev nyab xeeb thiab kev tiv thaiv tus kheej.
