Taw qhia

Caprylic acid yog cov xim tsis muaj xim crystalline. Nws yog ruaj khov nyob rau hauv cov xwm, insoluble nyob rau hauv dej tab sis soluble nyob rau hauv cov organic solvents. Caprylic acid muaj cov yam ntxwv qaub saj.

Caprylic acid muaj ntau yam kev siv hauv kev lag luam. Nws yog tsuas yog siv nyob rau hauv kev npaj ntawm polyester cob, uas yog siv nyob rau hauv kev tsim cov txheej, yas, roj hmab, fibers thiab polyester films, thiab lwm yam.

Muaj ntau txoj hauv kev los npaj octanoic acid. Ib txoj hauv kev yog los npaj nws los ntawm oxidation ntawm octene. Cov kauj ruam tshwj xeeb yog oxidize octene rau caprylyl glycol, thiab tom qab ntawd caprylyl glycol yog lub cev qhuav dej los tsim caprylic acid.

Caprylic acid yog khaus rau ntawm daim tawv nqaij thiab qhov muag, yog li nws yuav tsum tau ntxuav tam sim ntawd tom qab kev sib cuag. Cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav thaum ua haujlwm kom tsis txhob nqus nws cov vapors. Caprylic acid yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated, deb ntawm tshav kub thiab hluav taws.

Yav dhau los: Pimelic acid CAS Nr 111-16-0
