Ethyl nicotinate yog dab tsi?
Ethyl nicotinateyog ib qho tseem ceeb ntawm cov khoom siv raw khoom, uas yog dav siv nyob rau hauv synthesis ntawm tshuaj thiab tshuaj tua kab. Ethyl nicotinate yog xim tsis muaj xim rau cov kua daj daj nrog cov ntxhiab tsw tshwj xeeb. Nws yog insoluble hauv dej, tab sis soluble nyob rau hauv ntau cov organic solvents, xws li ethanol, ether, chloroform thiab hais txog. Nws yog ib qho tsis ruaj khov, yog li kev saib xyuas yuav tsum tau them rau qhov muaj peev xwm ntawm nws cov degradation thaum khaws cia thiab tuav.

Txoj kev npaj ntawm ethyl nicotinate:
CN106957262A nthuav tawm txoj kev npaj ntawmethyl nicotinate, uas yog tus cwj pwm hauv cov nicotinic acid, anhydrous ethanol thiab cov kua qaub acid catalyst rau esterification cov tshuaj tiv thaiv yog ntxiv rau hauv toluene, nplawm thiab hnov mob ntawm {{0}} DEG C rau 3-6 teev, ces rhuab thiab refluxed rau kev sib cais dej, thiab tom qab cov tshuaj tiv thaiv anhydrous sib cais tiav lawm, qhov kub thiab txias tau qis dua rau hauv chav tsev kub, cov khoom acid catalyst rau esterification cov tshuaj tiv thaiv tau zoo los ntawm filtration, thiab toluene rov qab los ntawm cov filtrate nyob rau hauv lub siab txo, thiab lub teeb daj pob tshab kua yog cov khoom tiav ethyl nicotinate; Cov molar piv ntawm nicotinic acid rau anhydrous ethanol yog 1: 1-1: 2, qhov hnyav piv ntawm nicotinic acid rau toluene yog 1: 0.3-1: 8, thiab qhov sib ntxiv ntawm khoom acid catalyst rau esterification cov tshuaj tiv thaiv yog 0.01-0.1 npaug ntawm qhov hnyav ntawm nicotinic acid; Cov khoom siv acid catalyst rau esterification cov tshuaj tiv thaiv yog HND230 khoom catalyst.
Lub invention muaj qhov zoo ntawm kev txo cov tiam ntawm cov dej khib nyiab heev, txo cov nqi zog thiab khoom siv thiab tsim nyog rau kev lag luam loj.
