Siv:
- ethyl l yog ib qho kev siv cov organic synthesis intermediate uas tuaj yeem siv los ua cov tshuaj, cov tshuaj hormones thiab cov khoom ntuj tsim.
-Nws tseem tuaj yeem siv los ua cov khoom siv hauv kev tshawb fawb tshuaj thiab tshuaj synthesis.
Txoj Kev Npaj:
ethyl feem ntau yog tsim los ntawm cov kauj ruam hauv qab no:
1. Ua ntej, methoxybenzofuran yog hloov nrog bromoacetic acid kom tau 5-methoxybenzofuran -2-acetic acid.
2. Tom qab ntawd, 5-methoxybenzofuran-2-acetic acid yog reacted nrog thionyl chloride (SOCl2) los hloov nws mus rau hauv acid chloride.
3. Thaum kawg, cov kua qaub chloride reacted nrog ethanol los tsim ethyl phenyl.
Cov ntaub ntawv kev nyab xeeb:
- ethyl l yog ib yam tshuaj uas yuav tsum tau ceev faj cia thiab tuav.
-Nws yog khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum muaj kev sib chwv tsis sib haum, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
-Nyob rau hauv kev siv, yuav tsum tswj kom zoo qhov cua, tsis txhob nqus pa thiab vapor.
