Taw qhia
FEMA 3148 yog ib qho organic compound nrog cov tshuaj formula C12H22O2. Nws yog cov kua tsis muaj xim nrog lub qab zib strawberry saj. Cov hauv qab no yog cov lus piav qhia txog qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb ntawm FEMA 3148:
Xwm:
-Cov tsos mob: cov kua tsis muaj xim
Molecular Luj: 194.3g / mol
- Melting point: -57 ° C
- Kub taw tes: 217 ° C
Qhov ceev: 0.88g / cm³
-Solubility: Insoluble hauv dej, me ntsis soluble hauv cawv
Siv:
- FEMA 3148 feem ntau yog siv rau hauv cov txuj lom thiab khoom noj khoom haus ntxiv los txhim kho strawberry, tshuaj ntsuab thiab ci tsw
-Tsis tas li ntawd, nws tseem tuaj yeem siv los ua ke rau lwm cov organic sib txuas, xws li Ester cov kuab tshuaj, txheej thiab yas additives, thiab lwm yam.
Txoj Kev Npaj:
Txoj kev npaj ntawm FEMA 3148 feem ntau siv cov kauj ruam hauv qab no:
1. Siv adipic acid raws li raw khoom, hexanol hexanoate yog synthesized los ntawm cawv transesterification cov tshuaj tiv thaiv.
2. Subjecting cov tau txais caproic acid ester mus rau lub cev qhuav dej condensation cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm ib tug muaj zog acid catalyst los tsim FEMA 3148.
Cov ntaub ntawv kev nyab xeeb:
- FEMA 3148 feem ntau muaj toxicity tsawg nyob rau hauv ib txwm siv.
-Nws yog cov kua ua kua, yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab kub, thiab khaws cia rau hauv qhov chaw txias, qhov cua zoo.
-siv yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, xws li kev sib chwv sib tsoo, yuav tsum tam sim ntawd yaug nrog dej kom ntau.
-hauv kev siv cov txheej txheem yuav tsum tau xyuam xim rau kev tiv thaiv kev ntsuas, suav nrog cov hnab looj tes, hnav cov khaub ncaws tiv thaiv tsim nyog thiab tsom iav tiv thaiv. Qhov chaw ua haujlwm yuav tsum tau muab ntxuav kom huv thiab huv tom qab ua haujlwm.
