Taw qhia

3-Methylpentanoic 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 3-methylpentanoic acid:

 

Zoo:

- Cov tsos mob: 3-Methylpenteric acid yog cov kua tsis muaj xim.

- Solubility: Soluble nyob rau hauv dej thiab cov organic solvents.

- Odor: Ib qho pungent qaub tsw.

 

Siv:

- 3-Methylpentanoic acid feem ntau yog siv los ua cov tshuaj nruab nrab hauv kev sib txuas ntawm lwm cov organic tebchaw.

- Nws kuj tseem siv tau los ua cov khoom siv hluav taws xob hauv qee qhov chaw.

 

Txoj kev:

- 3-Methylpenteric acid tuaj yeem tau txais los ntawm kev ntxiv polymerization ntawm propylene carbonate. Methylvaleric anhydride reacts nrog methacrylenol hauv cov tshuaj tiv thaiv hnyav los ua 3-methylpentanoate. Tom qab ntawd, 3-methylvaleric acid yog reacted nrog hydrocyanic acid kom tau 3-methylpentanoic acid.

 

Cov ntaub ntawv kev nyab xeeb:

- 3-Methylpentanoic acid yog ib qho khaus uas yuav ua rau khaus ntawm daim tawv nqaij thiab qhov muag. Cov hnab looj tes tiv thaiv thiab qhov muag tiv thaiv yuav tsum hnav thaum siv.

- Thaum lub sij hawm khaws cia thiab siv, nws yog ib qho tsim nyog yuav tsum tswj kom muaj qhov cua kom zoo thiab tsis txhob sib cuag nrog hluav taws.
