Tom ntej: Ethyl 2-methyl-5-nitronicotinate (CAS # 51984-71-5)
Taw qhia
Ethyl, tshuaj formula yog C9H9NO4. 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:
Ethyl yog daj crystalline hmoov los yog hmoov nrog ib tug greasy tsos thiab ib tug tshwj xeeb tsw. Nws yog soluble nyob rau hauv feem ntau cov organic solvents thiab tsawg soluble nyob rau hauv dej.
Siv:
Ethyl yog ib qho organic synthesis intermediate compound, uas yog siv dav hauv kev lag luam tshuaj tua kab thiab kev tsim tshuaj. Nws tuaj yeem siv los tsim ntau yam tshuaj lom neeg lom neeg, xws li tshuaj tua kab, fungicides, tshuaj tiv thaiv qog, thiab lwm yam.
Txoj Kev Npaj:
Ethyl feem ntau yog npaj los ntawm chemical synthesis. Ib txoj hauv kev yog los ntawm esterification ntawm 2-methyl-5-nitronicotinic acid. Hauv kev ua haujlwm tshwj xeeb, 2-methyl-5-nitronicotinic acid yog reacted nrog anhydride thiab alkaline catalyst los tsim Ethyl.
Cov ntaub ntawv kev nyab xeeb:
Ethyl tuaj yeem ua rau tawv nqaij thiab ua rau lub qhov muag, ua pa thiab ua pa. Yog li ntawd, kev tiv thaiv tsim nyog yuav tsum tau ua thaum tuav cov khoom, xws li hnav hnab looj tes thiab tsom iav tiv thaiv, kom ntseeg tau tias kev ua haujlwm tau ua tiav nyob rau hauv qhov cua zoo. Tsis tas li ntawd, nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, zoo-ventilated, deb ntawm combustibles thiab oxidants. Thov xa mus rau cov ntaub ntawv ntsig txog kev nyab xeeb thiab cov lus qhia ua haujlwm rau txhua qhov kev ua haujlwm nyab xeeb ntsig txog cov khoom no.
