m-Tolyldiethanolamine，also known as DEET (diethylamide N,N-dimethyl-3-hydramide), is a common insect repellent. It is soluble in organic solvents such as ester, alcohol, and ether, and slightly soluble in water. This compound has good heat resistance and light resistance.
m-Tolyldiethanolamine is mainly used as an insect repellent to prevent bites and harassment from mosquitoes, ticks, fleas, grasshoppers and other insects. Its efficacy lasts for a long time and has a high repellent effect on mosquitoes and other insects. It is widely used in outdoor activities, wilderness exploration and military protection and other fields.
There are many methods for preparing N,N-bishydroxyethyl m-toluidine. One of the commonly used methods is to react m-toluidine and formamide in the presence of an alkaline catalyst. Specific steps are as follows:
1. React formamide with m-toluidine under alkaline conditions to generate N-formyl m-toluidine.
2. Heat the reaction product under acidic conditions to convert N-formyl m-toluidine into N,N-bishydroxyethyl m-toluidine. -
