Pimelic acid (CAS # 111-16-0)

Heptanedic acid, tseem hu ua stearic acid lossis caprylic 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 heptanetic acid:

Zoo:
- Cov tsos mob: Heptaneic acid yog cov xim tsis muaj kob crystalline khoom lossis hmoov dawb.
- Solubility: Heptalaic acid yog soluble hauv cawv thiab ether solvents, insoluble hauv dej.

Siv:
- Heptaneric acid, raws li cov organic compound, muaj ntau yam kev siv hauv kev lag luam.

Txoj kev:
- Heptalaic acid tuaj yeem tau txais los ntawm acid-catalyzed oxidation ntawm cov roj. Feem ntau, heptalaic acid yog muab rho tawm los ntawm txiv maj phaub lossis xibtes roj.

Cov ntaub ntawv kev nyab xeeb:
- Heptanedic acid feem ntau suav hais tias yog ib qho chaw muaj kev nyab xeeb. Nws tsis tshua khaus rau ntawm daim tawv nqaij tab sis irritating ntawm lub qhov muag. Thaum siv los yog tuav cov tshuaj heptanoic acid, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab ua kom muaj qhov cua zoo. Nyob rau hauv rooj plaub ntawm kev sib cuag, yaug nrog dej tam sim ntawd thiab sab laj nrog kws kho mob.
- Heptanedic acid tsis ruaj khov thiab tuaj yeem hlawv thaum raug kub los yog qhib nplaim taws. Thaum khaws cia thiab siv, nws yuav tsum khaws cia kom deb ntawm qhov hluav taws kub thiab qhov kub thiab txias, thiab tsis txhob sib cuag nrog cov oxidants thiab muaj zog acids.
- Heptanedioic acid yuav tsum muab cia rau hauv ib lub thawv airtight nyob rau hauv qhov chaw txias, qhuav thiab zoo-ventilated.
