Xwm:

-Cov tsos mob: cov kua tsis muaj xim

-Boiling point: Txog 380 ℃

- Qhov ceev: txog 1.03g / cm³

-Solubility: Soluble hauv ethanol, ether thiab qee cov kuab tshuaj organic

Siv:

-Nws feem ntau yog siv los ua ib qho nruab nrab hauv cov tshuaj synthesis thiab yog siv rau hauv kev sib txuas ntawm lwm cov organic tebchaw.

-Nws tseem tuaj yeem siv ua tshuaj tua kab lossis tshuaj tua kab.

Txoj kev:

-los yog tuaj yeem npaj los ntawm esterification ntawm diacid thiab methanol. Txoj kev tshwj xeeb yog ntxiv undecanedioic acid thiab methanol rau hauv lub reactor, thiab nqa tawm esterification cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm ib tug catalyst. Tom qab ua tiav cov tshuaj tiv thaiv, cov khoom lag luam tau txais los ntawm kev ua haujlwm distillation thiab purification.

Cov ntaub ntawv kev nyab xeeb:

-Nws yog khaus thiab yuav ua rau khaus qhov muag thiab tawv nqaij. Kev saib xyuas yuav tsum tau them rau kev tiv thaiv tus kheej thaum tuav thiab siv, xws li hnav tsom iav tiv thaiv, hnab looj tes thiab khaub ncaws tiv thaiv.

-Tsis txhob sib cuag nrog cov oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai.

-Thaum khaws cia, khaws lub foob rau hauv qhov chaw qhuav, tsaus thiab qhov cua zoo.
