Taw qhia
Monomethyl suberate, tshuaj formula C9H18O4, yog ib qho organic compound. 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:
- Monomethyl suberate yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw tsis muaj zog ntawm chav sov.
-Nws qhov ceev yog li 0.97 g / mL, thiab nws qhov kub ntawm qhov kub ntawm 220-230 ° C.
- Monomethyl suberate muaj solubility zoo thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li cawv thiab ethers.
Siv:
- Monomethyl suberate tuaj yeem siv los tsim lwm cov organic sib txuas, xws li tsw, tshuaj ntsuab, tshuaj thiab dyes.
-Nws tseem tuaj yeem siv rau hauv cov ntawv thov xws li cov kuab tshuaj, cov roj nplua nyeem thiab cov yas yas.
Txoj Kev Npaj:
-Cov txheej txheem kev npaj ntawm Monomethyl suberate yog los ntawm esterification cov tshuaj tiv thaiv ntawm suberic acid thiab methanol. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv acidic tej yam kev mob siv cov kua qaub catalyst xws li sulfuric acid los yog ib tug methylating tus neeg saib xyuas xws li methylsulfuric acid.
Cov ntaub ntawv kev nyab xeeb:
- Monomethyl suberate tsawg toxicity, tab sis tseem yuav tsum tau xyuam xim rau kev siv nyab xeeb.
-Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Yog tias muaj kev sib cuag, yaug tam sim nrog dej ntau.
-hauv kev siv kom tswj tau qhov cua zoo, tsis txhob nqus nws vapor.
- Monomethyl suberate yog flammable thiab yuav tsum tau ceev kom deb ntawm hluav taws kub thiab kub.
-Storage yuav tsum tau muab kaw, nyob rau hauv ib qho chaw txias thiab qhuav, deb ntawm hluav taws kub thiab oxidizing neeg sawv cev.
