Used mainly in

Excellent plasticizer for polyamide resin and cellulose resin, with high compatibility.

Used in hot melt adhesives, coatings, and printing inks to improve flexibility and processing performance.

As a pharmaceutical intermediate, it is used for synthesizing active pharmaceutical ingredients.

It has applications in nylon, pigments, adhesives, and other fields.

Synthesis lines:

N-ethylortho/p-toluenesulfonylamide (CAS 8047-99-2) is typically synthesized using the following method:

Starting materials: o-toluenesulfonyl chloride or p-toluenesulfonyl chloride (or mixtures thereof).

Reaction type: Nucleophilic substitution reaction between sulfonyl chloride and ethylamine.

Reaction conditions:

Conducted in alkaline environments (such as triethylamine, sodium carbonate aqueous solution);

The solvent can be dichloromethane, acetonitrile, or a two-phase system of water/organic solvent;

The temperature is usually controlled between 0-40 ° C to avoid side reactions.

Product separation: Purification through extraction, washing, concentration, recrystallization, or 

vacuum distillation.

Product composition: The actual product is mostly a mixture of ortho - and para isomers (typical ratio: ortho 65-70%, para 25-30%).

This synthetic route belongs to a typical sulfonamide reaction and is widely used in the preparation of sulfonamide compounds
