Uses N-Ethyl-4-toluene sulfonamide is a resin carrier in dental materials used for isolating cavities below restorations; plasticizer in polyvinyl alcohollacquers, polyamides, cellulose acetate, etc. Uses N- Ethyl- p- toluenesulfonamide is a reagent used in the sulfonamidation of imidazopyridines. General Description Platelets (from dilute alcohol or ligroin) or off-white solid. Air & Water Reactions Insoluble in water. Reactivity Profile An amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). Fire Hazard Flash point data for N-Ethyl-p-toluenesulfonamide are not available; however, N-Ethyl-p-toluenesulfonamide is probably combustible.   N-Ethyl-p-toluenesulfonamide Preparation Products And Raw materials Raw materials Ethyl acetate-->Sodium bicarbonate-->Tosyl chloride-->Ethylamine
