Taw qhia
(11-Hydroxyundecyl) phosphonic acid yog ib qho organophosphorus compound nrog phosphoric acid thiab hydroxyl functional pawg. Nws cov khoom yog dawb crystalline solids, tsis tshua muaj solubility, soluble nyob rau hauv organic solvents xws li ethanol, acetonitrile, thiab lwm yam.
Chemically, (11-hydroxyundecyl) phosphonic acid yuav siv tau raws li surfactants, emulsifiers thiab preservatives, thiab lwm yam, thiab feem ntau yog siv nyob rau hauv lubricating roj, preservatives, nto kho mob thiab lwm yam teb. Nws txoj kev npaj tuaj yeem tau txais los ntawm phosphoric acid chlorination, thiab tom qab ntawd ua ke los ntawm cov tshuaj tiv thaiv nrog cov sib xyaw hydroxyl compound.
Cov ntaub ntawv kev nyab xeeb: (11-Hydroxyundecyl) phosphonic acid yuav tsum tau ua tib zoo saib xyuas thaum siv kom tsis txhob muaj kev sib cuag nrog cov tawv nqaij, qhov muag, thiab nqus pa. Nws yog ib qho tsim nyog los xyuas kom meej tias koj ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo thiab muaj kev tiv thaiv tus kheej tsim nyog. Thaum khaws cia thiab tuav, kev sib cuag nrog cov oxidants yuav tsum tau zam kom tsis txhob muaj kev phom sij txaus ntshai.
