Taw qhia
2-Methylvaleric acid, tseem hu ua isovaleric acid, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-methylpentanoic acid:
Zoo:
Cov tsos mob: 2-methylpenteric acid yog cov kua tsis muaj xim nrog cov ntxhiab tsw ntxhiab ntawm chav tsev kub.
Solubility: Nws tuaj yeem yaj hauv dej thiab cov kuab tshuaj organic (xws li cawv, ethers, esters).
Siv:
Kev siv tshuaj lom neeg: 2-methylpenteric acid tuaj yeem siv los ua cov khoom siv tseem ceeb rau kev sib txuas ntawm lwm cov organic sib txuas, xws li kev npaj cov tshuaj tsw qab, esters, thiab lwm yam.
Txoj kev:
2-methylpenteric acid tuaj yeem tau txais los ntawm oxidation synthesis ntawm ethylene los ntawm alpaca catalyst, thiab 2-methylpenteraldehyde yog tsim nyob rau hauv cov tshuaj tiv thaiv, uas yog tom qab txo mus rau 2-methylpenteric acid los ntawm hydroxyl ions los yog lwm yam kev txo cov tshuaj.
Cov ntaub ntawv kev nyab xeeb:
2-Methylpentanoic acid yog ib yam khoom uas ua rau khaus, thiab yuav tsum tau ceev faj thaum sib cuag nrog daim tawv nqaij thiab qhov muag kom tsis txhob khaus tawv nqaij thiab qhov muag puas.
Thaum siv thiab khaws cia 2-methylpentanoic acid, kev sib cuag nrog cov oxidizing muaj zog thiab kub kub yuav tsum raug zam kom tsis txhob muaj hluav taws kub los yog tawg.
Ua tib zoo saib xyuas qhov cua zoo thaum lub sijhawm ua haujlwm thiab tsis txhob nqus cov pa.
Nyob rau hauv rooj plaub ntawm kev sib cuag nrog los yog tsis pom kev noj ntawm 2-methylpentanoic acid, yaug tam sim ntawd nrog dej txaus thiab nrhiav kev kho mob sai li sai tau.
