Quaternary ammonium compounds (feem ntau hu ua quats lossis QACs) yog cationic surfactants (cov neeg ua haujlwm saum npoo av) uas sib txuas cov kab mob thiab cov kab mob (feem ntau tsuas yog cov kab mob hauv lub hnab) kev ua haujlwm nrog cov tshuaj ntxuav tes zoo thiab, yog li ntawd, tu muaj peev xwm..
ob qhov txiaj ntsig ntawm quaternary ammonium compounds yog dab tsi?
Txoj kev phem. Ib qho ntawm qhov zoo ntawm cov tshuaj tua kab mob quaternary ammonium yog tias lawv tsis txhob ua kom cov khaub ncaws thiab ntaub pua plag zoo li cov tshuaj bleach ua. Lawv kuj tsis yog-corrosive rau cov kav hlau thiab lwm qhov chaw, lwm qhov zoo dua li tshuaj dawb.
Vim li cas thiaj hu ua quaternary ammonium?
ib qho ntawm cov ntsev tau los ntawm ammonium uas cov nitrogen atom txuas rau plaub pawg organic, xws li benzalkonium chloride; cov ntsev yog cationic nto-active compounds siv los ua tshuaj tua kab mob thiab tshuaj tua kab mob. Kuj hu ua quaternary ammonium ntsev.
Yuav ua li cas quats tshuaj tua kab mob?
Quats suav nrog khoom siv ntxuav kom tua kab mob thiab kab mob. Quats muaj cov khoom zoo uas khi rau cov hlwb tsis zoo hauv cov kab mob.
Vim li cas quaternary amines raug nqi zoo?
Quaternary ammonium cations yog qhov zoo them ions nrog cov qauv NR4 + nrog N yog nitrogen atom thiab R yog alkyl pawg uas muaj cov pa roj carbon thiab hydrogen atoms teem rau hauv cov saw hlau. Lawv yog tas mus li them, ntawm nws tus kheej ntawm acidity ntawm lawvsolution.
