Nws melting point yog nyob rau hauv thaj tsam ntawm 52-56 degrees Celsius. Lub compound yog ib tug variant ntawm fatty acid nrog ib pab pawg neeg hydroxyl thiab ib tug kaum ib carbon saw qauv.
Siv:
11-HYDROXYUNDECANOIC ACID yog dav siv hauv kev lag luam tshuaj. Nws yog feem ntau siv nyob rau hauv cov synthesis ntawm surfactants, polymers, lubricants, thickeners thiab emulsifiers. Tsis tas li ntawd, nws tseem tuaj yeem siv los npaj cov organosilicon tebchaw thiab dye intermediates.
Txoj kev:
Muaj ntau txoj hauv kev los ua ke 11-HYDROXYUNDECANOIC ACID, ib qho uas tau los ntawm ester hydrolysis cov tshuaj tiv thaiv ntawm Undecanoic ACID thiab sodium hydroxide hauv ethanol tov, tom qab acidification muab 11-HYDROXYUNDECANOIC ACID. Lwm txoj hauv kev suav nrog oxidation cov tshuaj tiv thaiv, txo carbonyl, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
11-HYDROXYUNDECANOIC ACID feem ntau suav tias yog ib qho chaw nyab xeeb, tab sis cov txheej txheem kev nyab xeeb yuav tsum tau ua. Thaum tuav cov khoom sib xyaw no, nws raug nquahu kom hnav cov tsom iav tiv thaiv, hnab looj tes thiab cov tsho hauv chav kuaj. Tsis txhob nqus nws cov vapors thiab kov daim tawv nqaij. Cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw yuav tsum tau nkag siab meej ua ntej siv, thiab khaws cia thiab ua raws li qhov tsim nyog. Thaum muaj kev tsis xis nyob, nrhiav kev kho mob tam sim ntawd.
