2- ethyl phenol is used as a reagent for the synthesis of Phenoxy Acetic acid derivatives, as a new free fatty acid receptor 1 agonist, for the treatment of diabetes. 2-ethylphenol is also used in the preparation of aminoquinazoline toll like receptor ligands and potential immunotherapy.

4,4'-Bis(diethylamino)benzophenone is an important intermediate of basic dyes. It is used in the production of basic brilliant blue B and basic brilliant blue R.

Carboxymethyl cellulose (CMC) is a tackifier. It is a non-toxic and tasteless white flocculent powder at room temperature. It has stable performance and is easily soluble in water. Its aqueous solution is neutral or alkaline transparent viscous liquid, soluble in other water-soluble adhesives and resins, insoluble in ethanol and other chemical Book organic solvents. Carboxymethyl cellulose is the product of carboxymethyl group substitution of cellulose. According to its molecular weight or degree of substitution, it can be a completely soluble or insoluble polymer. The latter can be used as a weak acid cation exchanger to separate neutral or basic proteins.

Emulsifier NP-10 is a colorless transparent liquid. It has good wetting, emulsifying, dispersing and leveling properties. It is prepared by heating and catalytic condensation of nonylphenol and 9 moles of ethylene oxide.

Ethyl cellulose is abundantly used in coatings. Can also be used as a basic material for solid lubricants for stamping of metal workpieces. In microcircuit printing, ethyl cellulose is used as a color carrier. In the radio industry, it is used as a high-grade insulating material, and in protective coatings as special films such as cladding layers for rocket emitters. They can be used as hot-melt type glue and coatings for cables, paper, textiles, etc., and can also be used as insulation of extrusion wires and as toughness enhancers for plastics. It is also used for pigment grinding bases, for printing inks, for molded plastic powders, for explosive fuse, and in the formulation of vitamins, among others. Used as a removable protective layer for metal parts against corrosion, disfigurement before use, and also as a removable coating to protect friable glassware. There are various uses remaining in adhesives, textile and fibers, medicine and food, and other industries. Industrial grade ethyl cellulose is used in coatings (gel type coatings, hot melt coatings), inks (screen printing inks, photographic concave brushing inks), adhesives, pigment pastes, etc. higher grade products are used in medicine, cosmetics and food, for example, pharmaceutical tablet packaging materials, binders for long-term preparations, etc.
