Taw qhia

Succinic acid yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm succinic acid:

Zoo:

- Zoo li: tsis muaj xim crystalline khoom

- Solubility: Succinic acid yog yooj yim soluble hauv dej thiab qee cov kuab tshuaj organic

- Cov khoom siv tshuaj: Succinic acid yog cov kua qaub tsis muaj zog uas cuam tshuam nrog alkali tsim cov ntsev. Lwm cov khoom siv tshuaj muaj xws li kev cuam tshuam nrog cawv, ketones, esters, thiab lwm yam, uas tuaj yeem ua rau lub cev qhuav dej, esterification, carboxylic acidification thiab lwm yam kev cuam tshuam.

Siv:

- Muaj kev siv: Succinic acid tuaj yeem siv rau hauv kev npaj cov polymers xws li yas, resins thiab roj hmab, xws li plasticizers, modifiers, coatings thiab adhesives.

Txoj kev:

Muaj ntau txoj kev npaj tshwj xeeb, suav nrog reacting butalic acid nrog hydrogen nyob rau hauv lub xub ntiag ntawm catalyst, los yog reacting nws nrog carbamate.

Cov ntaub ntawv kev nyab xeeb:

- Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab yaug tam sim nrog dej ntau yog tias tiv tauj.

- Tsis txhob nqus cov plua plav succinic acid los yog vapors thiab tuav lub qhov cua kom zoo.

- Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum tuav succinic acid.

Yav dhau los: Heptanoic acid (CAS # 111-14-8)
