1. Cov ntsev ammonium Quaternary yog cov tshuaj uas tsim los ntawm kev hloov tag nrho plaub lub hydrogen atoms hauv ammonium ions nrog cov pab pawg alkyl.

Lawv yog cov cationic surfactant nrog cov khoom zoo heev bactericidal, thiab qhov zoo ntawm lawv cov kev ua haujlwm bactericidal yog pawg cationic tsim los ntawm kev sib xyaw ua ke ntawm cov hauv paus organic thiab cov nitrogen atoms.
2. Txij li xyoo 1935, thaum cov neeg German pom cov txiaj ntsig ntawm alkyl dimethyl ammonium gasification, lawv siv nws los kho cov khaub ncaws tub rog kom tiv thaiv kev kis kab mob. Kev tshawb fawb txog cov khoom siv tua kab mob quaternary ammonium ntsev yeej ib txwm yog qhov tseem ceeb ntawm cov kws tshawb fawb. Cov khoom siv tua kab mob uas npaj nrog quaternary ammonium ntsev muaj cov khoom tua kab mob zoo thiab tuaj yeem siv dav hauv ntau qhov chaw xws li tshuaj, kev kho dej, thiab zaub mov.
3. Cov haujlwm ntawm cov ntsev quaternary ammonium muaj xws li:

Cov tshuaj tua kab mob ua liaj ua teb, cov tshuaj tua kab mob rau pej xeem, cov tshuaj tua kab mob hauv dej, cov tshuaj tua kab mob hauv aquaculture, cov tshuaj tua kab mob rau kev kho mob, cov tshuaj tua kab mob rau tsiaj txhu thiab nqaij qaib, cov tshuaj tua kab mob red tide, cov tshuaj tua kab mob algae xiav-ntsuab, thiab lwm yam kev tua kab mob thiab tua kab mob. Tshwj xeeb tshaj yog Gemini quaternary ammonium ntsev muaj cov teebmeem tua kab mob zoo heev thiab cov nqi qis.

Tetrabutylammonium bromide (TBAB), tseem hu ua tetrabutylammonium bromide.

Nws yog ib qho ntsev organic nrog cov mis molecular C₁₆ H₃₆BrN.

Cov khoom ntshiab yog cov siv lead ua dawb los yog hmoov, nrog rau qhov tsw qab tshwj xeeb thiab tsw qab tshwj xeeb. Nws ruaj khov ntawm qhov kub thiab txias hauv chav tsev thiab qhov siab ntawm huab cua. Yaj hauv dej, cawv, thiab acetone, yaj me ntsis hauv benzene.

Cfeem ntau siv ua ib qho nruab nrab hauv cov organic synthesis, theem hloov catalyst, thiab ion khub reagent.
