Taw qhia
Lactic acid ethyl ester yog cov organic compound.
Ethyl lactate yog cov kua tsis muaj xim uas muaj cawv txiv hmab txiv ntoo tsw ntawm chav tsev kub. Nws yog soluble hauv cov kuab tshuaj organic xws li cawv, ethers, thiab aldehydes, thiab tuaj yeem cuam tshuam nrog dej los tsim lactic acid.
Ethyl lactate muaj ntau yam kev siv. Hauv kev lag luam txuj lom, nws feem ntau yog siv los ua cov khoom xyaw hauv kev npaj cov txiv hmab txiv ntoo flavors. Thib ob, hauv cov organic synthesis, ethyl lactate tuaj yeem siv los ua cov kuab tshuaj, catalyst, thiab nruab nrab.
Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm ethyl lactate. Ib qho yog los ua cov tshuaj lactic acid nrog ethanol thiab raug esterification cov tshuaj tiv thaiv los tsim ethyl lactate. Lwm qhov yog ua rau cov tshuaj lactic acid nrog acetic anhydride kom tau ethyl lactate. Ob txoj kev yuav tsum tau muaj cov catalyst xws li sulfuric acid los yog sulfate anhydride.
Ethyl lactate yog cov tshuaj lom neeg tsawg, tab sis tseem muaj qee qhov kev tiv thaiv kev nyab xeeb yuav tsum tau coj mus rau hauv tus account. Kev raug ethyl lactate tuaj yeem ua rau qhov muag thiab tawv nqaij khaus, thiab cov khoom siv tiv thaiv tsim nyog yuav tsum tau hnav thaum siv nws. Tsis txhob raug cov nplaim taws qhib thiab kub siab los tiv thaiv kev sib tsoo lossis tawg. Thaum siv lossis khaws cia ethyl lactate, yuav tsum tau saib xyuas kom tsis txhob muaj cov tshuaj tua hluav taws thiab cov oxidizing cov neeg ua haujlwm. Yog tias ethyl lactate tau noj lossis nqus tau, nrhiav kev kho mob tam sim ntawd.
