112110-16-4|5-Methylpyridine-2,3-dicarboxylic Acid Dimethyl Ester

Daim ntawv thov:

DMMP feem ntau yog siv los ua ib qho tseem ceeb hauv kev tshawb fawb thiab kev siv tshuaj. Nws ua hauj lwm raws li ib tug tseem ceeb raw khoom rau lub synthesis ntawm organophosphorus tebchaw thiab kev npaj ntawm catalysts. Tsis tas li ntawd, nws tuaj yeem siv los ua cov kuab tshuaj hauv cov organic synthesis, xws li cyanation thiab hydrogenation cov tshuaj tiv thaiv.

Txoj kev ntawm Synthesis:

Cov lus piav qhia rau txoj kev ntawm kev sib txuas:

Ntxiv sodium ethoxide thiab xylene rau 500ml plaub-caj dab, tom qab ntawd maj mam qhia dimethyl oxalate, ua kom lub cev txias thaum lub sijhawm ntxiv. Tom ntej no, ntxiv methyl chloroacetate dropwise, tswj lub cev kub ntawm kwv yees li 40 degree. Tom qab qhov sib ntxiv ua tiav, tso cai rau cov tshuaj tiv thaiv mus rau kev khaws cia kub li 2 teev.
Siv 1000 ml plaub- caj dab caj dab, ntxiv sulfamic acid, thiab ntxiv dej kom yaj tag. Tom qab ntawd ntxiv dimethyl 2-chloro-3-oxobutyrate, thiab ua kom sov rau reflux. Nyob rau hauv cov xwm txheej reflux, ntxiv 2-methylpropenal dropwise. Tom qab qhov sib ntxiv ua tiav, distilled tawm dej thiab xylene hauv qhov system. Tom qab ntawd ntxiv trimethylbenzene thiab rho tawm cov khoom.
