Taw qhia
4-Methylcaprylic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- 4-Methylcaprylic acid yog cov xim tsis muaj xim rau cov kua daj daj nrog ib qho tshwj xeeb mint aroma.
- 4-Methylcaprylic acid yog soluble hauv cov kuab tshuaj organic xws li cawv thiab ethers ntawm chav tsev kub. Nws muaj tsawg solubility hauv dej.
Siv:
- Nws kuj yog siv los ua ib qho catalyst rau qee cov polymers, pab kho qhov ceev thiab zoo ntawm cov tshuaj tiv thaiv polymerization.
- 4-Methylcaprylic acid kuj tuaj yeem siv rau hauv kev npaj ntawm qee qhov sib txuas, xws li polyester thiab polyurethane.
Txoj kev:
- Muaj ntau txoj hauv kev los npaj 4-methylcaprylic acid, thiab txoj kev siv feem ntau yog tau los ntawm cov tshuaj tiv thaiv ntawm n-caprylic acid nrog methanol. Thaum cov tshuaj tiv thaiv tshwm sim, pawg methyl hloov ib qho ntawm hydrogen atoms ntawm caprylic acid los tsim 4-methylcaprylic acid.
Cov ntaub ntawv kev nyab xeeb:
- 4-Methylcaprylic acid kuj muaj kev nyab xeeb nyob rau hauv kev siv dav dav, tab sis tseem muaj qee qhov caveats.
- Thaum khaws cia thiab tuav 4-methylcaprylic acid, khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab oxidizing cov neeg ua haujlwm, thiab tsis txhob sib cuag nrog cov muaj zog oxidizing lossis txo cov neeg ua haujlwm.
