Taw qhia
FEMA 2899 (Isobutyl 3-phenylpropionate) yog ib qho organic compound nrog cov tshuaj formula C13H18O2. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
FEMA 2899 yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws muaj qhov tsawg vapor siab thiab solubility, thiab yog insoluble hauv dej.
Siv:
FEMA 2899 feem ntau yog siv los ua cov tshuaj nruab nrab, ib qho kev sib txuas uas ua haujlwm raws li kev sib txuas lossis kev hloov pauv hauv cov txheej txheem synthesis. Nws yog feem ntau siv nyob rau hauv kev npaj ntawm flavors thiab fragrances, ntxiv tsw los yog kho qhov tsw. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov kuab tshuaj rau cov organic synthesis.
Txoj Kev Npaj:
FEMA 2899 feem ntau yog npaj los ntawm esterification cov tshuaj tiv thaiv ntawm isobutanol thiab 3-phenylpropionic acid. Nyob rau hauv cov tshuaj tiv thaiv, isobutanol thiab 3-phenylpropionic acid yog ntxiv rau cov tshuaj tiv thaiv hlab ntsha nyob rau hauv ib tug tsim nyog piv, ib tug catalyst xws li sulfuric acid yog ntxiv thiab rhuab, thiab lub resulting FEMA 2899 khoom yog sau.
Cov ntaub ntawv kev nyab xeeb:
FEMA 2899 tsis muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig hauv kev siv ib txwm muaj. Txawm li cas los xij, ua ib qho tshuaj, nws tseem yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thaum siv. Nws raug nquahu kom hnav cov kev tiv thaiv tsim nyog xws li hnab looj tes, tsom iav thiab cov khaub ncaws tiv thaiv thaum ua haujlwm kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Nws yuav tsum tau khaws cia kom tsis txhob sib cuag nrog oxidants, muaj zog acids, muaj zog hauv paus thiab lwm yam khoom kom tsis txhob muaj kev phom sij txaus ntshai. Nyob rau hauv txhua rooj plaub, cov txheej txheem ua haujlwm raug thiab cov lus pom zoo rau kev siv nyab xeeb yuav tsum tau ua raws. Nyob rau hauv rooj plaub ntawm kev sib tsoo los yog kev sib tsoo, kev ntsuas tsim nyog yuav tsum tau ua. Rau cov ntaub ntawv kev nyab xeeb tshwj xeeb thiab cov lus pom zoo ua haujlwm, kev siv yuav tsum tau ua rau cov ntaub ntawv tiv thaiv kev nyab xeeb thiab cov lus qhia rau kev siv.
