Hydroxamic acids yog ib chav kawm ntawm cov organic tebchaw uas muaj -C(=O)–N–OH ua haujlwm pab pawg, dav siv nyob rau hauv cov tshuaj thiab kev lag luam sectors. Lawv lub luag haujlwm tseem ceeb nyob hauv lawv lub peev xwm los tsim cov chelates ruaj khov nrog cov hlau ions; Yog li ntawd, lawv nquag ua haujlwm rau kev xaiv cais thiab rho tawm cov ions zoo li no. Piv txwv li, nyob rau hauv cov ntxhia metallurgy, hydroxamic acids ua haujlwm flotation agents rau cov hlau tsis yog -ferrous; los ntawm kev khi rau cov hlau nto, lawv hloov cov khoom nto thiab yog li txhim kho flotation efficiency.
Cov pab pawg ua haujlwm nquag ntawm hydroxamic acids muaj peev xwm tsim kev sib koom tes nrog cov hlau ions thaum tib lub sijhawm nthuav tawm cov kua qaub uas tso cai rau kev tswj hwm cov tshuaj pH. Qhov kev txiav txim chelating no tsis tsuas yog txhim kho kev ruaj ntseg ntawm cov hlau ions hauv kev daws teeb meem tab sis kuj tseem ua rau kev xaiv passivation ntawm cov hlau tshwj xeeb, yog li inhibiting cov adsorption ntawm impurity hlau. Cov yam ntxwv no muaj txiaj ntsig zoo rau hydroxamic acids nrog cov txiaj ntsig tseem ceeb hauv thaj chaw ntawm metallurgy, kev kho ib puag ncig, thiab kev sib cais tshuaj.
Tshaj li cov ntxhia hauv metallurgy, hydroxamic acids kuj pom daim ntawv thov hauv kev kho dej, tiv thaiv corrosion, thiab organic synthesis. Nyob rau hauv lub cheeb tsam ntawm kev kho dej, lawv khi nrog hnyav hlau ions los txo cov dej paug; hauv kev tiv thaiv corrosion, lawv tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto kom tiv thaiv cov txheej txheem corrosion; thiab nyob rau hauv cov organic synthesis, hydroxamic acids ua hauj lwm raws li intermediates nyob rau hauv ntau yam tshuaj tiv thaiv. Cov luag haujlwm sib txawv no qhia txog ntau yam ntawm hydroxamic acids hauv ob qho tib si kev lag luam thiab kev tshawb fawb tshawb fawb.
