m-Tolyldiethanolamine, tseem hu ua DEET (diethylamide N, N-dimethyl-3-hydramide), yog ib hom tshuaj tua kab. Nws yog soluble hauv cov kuab tshuaj organic xws li ester, cawv, thiab ether, thiab me ntsis soluble hauv dej. Cov khoom siv no muaj cov cua sov zoo thiab lub teeb ua haujlwm.
m-Tolyldiethanolamine feem ntau yog siv los ua cov tshuaj tua kab los tiv thaiv kev tua thiab ua phem los ntawm yoov tshaj cum, yoov tshaj cum, nyom nyom thiab lwm yam kab. Nws txoj kev ua tau zoo siv sijhawm ntev thiab muaj kev tiv thaiv zoo rau yoov tshaj cum thiab lwm yam kab. Nws yog dav siv hauv kev ua si sab nraum zoov, kev tshawb nrhiav hav zoov thiab kev tiv thaiv tub rog thiab lwm yam kev lag luam.
Muaj ntau txoj hauv kev los npaj N, N-bishydroxyethyl m-toluidine. Ib txoj hauv kev siv feem ntau yog ua rau m-toluidine thiab formamide nyob rau hauv lub xub ntiag ntawm alkaline catalyst. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:

1. React formamide nrog m-toluidine nyob rau hauv alkaline tej yam kev mob los tsim N-formyl m-toluidine.
2. Thaum tshav kub kub cov tshuaj tiv thaiv nyob rau hauv acidic tej yam kev mob los hloov N-formyl m-toluidine rau hauv N, N-bishydroxyethyl m-toluidine.
