Taw qhia
Malic ester yog ib qho organic compound.
Apple ester kuj tseem siv los ua cov khoom siv raw hauv cov kuab tshuaj, txheej, yas, thiab cov khoom siv fiber ntau.
Ib txoj hauv kev rau kev npaj ntawm malic esters yog esterification ntawm malic acid thiab cawv los ntawm acid catalysts. Thaum lub sij hawm cov tshuaj tiv thaiv, pawg carboxyl nyob rau hauv malic acid ua ke nrog cov hydroxyl pawg nyob rau hauv cawv los ua ib pawg ester, thiab cov kua ester yog tsim nyob rau hauv qhov kev txiav txim ntawm cov kua qaub catalyst.
Cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug sau tseg hauv kev siv cov kua ester:
1. Kua ester yog ib qho organic compound, uas yog cov nplaim hluav taws kub, tsis txhob sib cuag nrog cov nplaim taws qhib thiab kub kub.
2. Tsis txhob kov daim tawv nqaij, ua rau khaus lossis ua xua. Cov hnab looj tes thiab tsom iav tiv thaiv yuav tsum hnav thaum siv.
3. Kua ester muaj cov ntxhiab tsw zoo, thiab qhov ntev ntev yuav ua rau cov tsos mob tsis xis nyob xws li kiv taub hau, xeev siab, thiab ua tsis taus pa nyuaj, thiab yuav tsum tau khaws cia ib puag ncig zoo.
4. Kua ester tsuas yog siv rau kev lag luam siv, nws yog txwv tsis pub coj nws sab hauv lossis ncaj qha rau ntawm daim tawv nqaij.
5. Thaum siv applelate, thov xa mus rau daim ntawv qhia txog kev nyab xeeb thiab ua raws li cov lus qhia rau kev siv.
