1. Munyu we quaternary ammonium imakemikari anoumbwa nekutsiva maatomu ese mana ehydrogen mumaion e ammonium nemapoka ealkyl.

I cationic surfactant ine hunhu hwakanaka hwekuuraya mabhakitiriya, uye chikamu chinoshanda chebasa ravo rekuuraya mabhakitiriya iboka re cationic rinoumbwa nekusanganiswa kwemidzi ye organic nemaatomu e nitrogen.
2. Kubva muna 1935, apo maGerman akawana simba rekuuraya mabhakitiriya realkyl dimethyl ammonium gasification, vakarishandisa kurapa yunifomu dzemauto kudzivirira hutachiona hwemaronda. Tsvakurudzo yezvinhu zvinorwisa mabhakitiriya zvequaternary ammonium salt yagara iri chinhu chikuru chinotariswa nevaongorori. Zvinhu zvinorwisa mabhakitiriya zvakagadzirwa nequaternary ammonium salts zvine hunhu hwakanaka hwekurwisa mabhakitiriya uye zvinogona kushandiswa zvakanyanya munzvimbo dzakawanda dzakadai semishonga, kurapwa nemvura, uye chikafu.
3. Mabasa emunyu we quaternary ammonium anosanganisira:

Mishonga yekuuraya fungi yekurima, mishonga yekuuraya fungi munzvimbo dzeveruzhinji, mishonga yekuuraya fungi yemumvura inotenderera, mishonga yekuuraya zvipembenene muminda yemvura, mishonga yekuuraya zvipembenene muzvipatara, mishonga yekuuraya zvipembenene muzvipfuyo nedzimba dzehuku, mishonga yekuuraya zvipembenene mured tide, mishonga yekuuraya zvipembenene mualgae yebhuruu-girini, uye mimwe minda yekuuraya zvipembenene. Kunyanya munyu weGemini quaternary ammonium une mhedzisiro yakanaka yekuuraya zvipembenene uye mutengo wakaderera.

Tetrabutylammonium bromide (TBAB), inozivikanwawo se tetrabutylammonium bromide.

Munyu weorganic une fomura yemamorekuru C ₁₆ H₃₆BrN.

Chigadzirwa chakachena ikristaro chena kana upfu, chine hunyoro uye hwema hwakasiyana. Chinogara kwenguva refu kana tembiricha yemumba uye kumanikidzwa kwemhepo. Chinonyungudika mumvura, doro, uye acetone, chinonyungudika zvishoma mubenzene.

CInoshandiswa chete sechikamu chepakati mukugadzirwa kweorganic, phase transfer catalyst, uye ion pair reagent.
