Taw qhia
acid ethyl ester yog ib qho organic compound nrog cov tshuaj formula C8H8BrNO2. Nws yog cov kua tsis muaj xim uas muaj ntxhiab tsw tshwj xeeb. Cov compound yog soluble hauv cov kuab tshuaj organic xws li ethanol, dimethylformamide thiab benzene, thiab insoluble hauv dej.
acid ethyl ester muaj ntau yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv los ua cov tshuaj nruab nrab rau kev sib txuas ntawm ntau yam tshuaj thiab bioactive molecules. Tsis tas li ntawd, nws kuj tuaj yeem siv rau hauv Gormperman cov tshuaj tiv thaiv thiab palladium-catalyzed cross-coupling cov tshuaj tiv thaiv hauv cov organic synthesis.
Muaj ob txoj hauv kev rau acid ethyl ester:
1. Nws tau txais los ntawm cov tshuaj tiv thaiv ntawm 6-bromopyridine thiab chloroacetate, thiab tom qab ntawd hydrolyzed nrog alkali tom qab cov tshuaj tiv thaiv.
2. Los ntawm 6-bromopyridine thiab chloroacetic acid ester cov tshuaj tiv thaiv, acid chloride, thiab tom qab ntawd hnov mob nrog cawv kom tau txais cov khoom.
Yuav tsum tau ceev faj txog kev nyab xeeb thaum siv thiab khaws cia cov kua qaub ethyl ester. Nws yog cov kua nplaum uas muaj nplaim taws thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua zoo, kom deb ntawm hluav taws kub thiab kub. Cov cuab yeej tiv thaiv tsim nyog, xws li cov hnab looj tes kuaj thiab tsom iav, yuav tsum hnav thaum ua haujlwm. Yog tias noj los yog sib cuag nrog daim tawv nqaij lossis qhov muag, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
