Betaine series amphoteric surfactants yog amphoteric surfactants uas muaj zog alkaline N atoms.Lawv yog cov ntsev nruab nrab tiag tiag nrog ntau yam isoelectric.Lawv qhia cov yam ntxwv dipole nyob rau hauv ntau yam.Muaj ntau cov pov thawj uas betaine surfactants muaj nyob rau hauv daim ntawv ntawm ntsev sab hauv.Yog li ntawd, nws yog qee zaum hu ua quaternary ammonium nrog ntsev surfactant.Raws li qhov sib txawv ntawm cov chaw nqa khoom tsis zoo, cov betaine surfactants tau tshaj tawm hauv kev tshawb fawb tam sim no tuaj yeem muab faib ua carboxyl betaine, sulfonic betaine, phosphoric betaine, thiab lwm yam.

Betaine series amphoteric surfactants yog cov ntsev nruab nrab nrog ntau yam isoelectric.Lawv qhia cov yam ntxwv dipole nyob rau hauv ib tug dav pH ntau.Vim muaj cov quaternary ammonium nitrogen nyob rau hauv cov molecules, feem ntau betaine surfactants muaj tshuaj zoo stability nyob rau hauv acidic thiab alkaline xov xwm.Ntev npaum li cov molecule tsis muaj cov pab pawg ua haujlwm xws li ether daim ntawv cog lus thiab ester daim ntawv cog lus, nws feem ntau muaj qhov zoo oxidation tsis kam.

Betaine series amphoteric surfactants yog yooj yim rau yaj nyob rau hauv dej, nyob rau hauv concentrated acids thiab bases, thiab txawm nyob rau hauv concentrated daws ntawm inorganic ntsev.Lawv tsis yooj yim ua nrog alkaline ntiaj teb hlau thiab lwm yam hlau ions.Ntev saw betaine yog ib qho yooj yim rau yaj hauv nruab nrab aqueous thiab tsis cuam tshuam los ntawm pH.Solubility ntawm betaine feem ntau cuam tshuam los ntawm cov pa roj carbon atoms.Lub concentration ntawm lauramide propyl betaine sx-lab30 yaj nyob rau hauv aqueous nruab nrab tuaj yeem ncav cuag 35%, tab sis solubility ntawm homologues nrog ntev carbon chains yog tsawg heev.

Lub zog dej tsis kam ntawm surfactants yog tshwm sim nyob rau hauv lawv kam rau calcium thiab magnesium nyuaj ions thiab lawv dispersing zog rau calcium xab npum.Ntau cov betaine amphoteric surfactants qhia zoo heev stability rau calcium thiab magnesium ions.Calcium ion stability ntawm feem ntau sulfobetine amphoteric surfactants yog ruaj khov, thaum calcium ion stability tus nqi ntawm cov sib txuas amine compounds yog qis dua.

Betaine series amphoteric surfactants yog nplua nuj nyob rau hauv ua npuas ncauj.Tom qab kev sib xyaw nrog anionic surfactants, cov molecules cuam tshuam zoo heev.Cov nyhuv ntawm foaming thiab tackling yog nce ntau.Ntxiv mus, cov khoom ua npuas ncauj ntawm beet beet surfactants tsis cuam tshuam los ntawm hardness ntawm dej thiab PH ntawm nruab nrab.Lawv yog siv los ua foaming agents lossis foamers, thiab tuaj yeem siv ntau yam PH.
