1. Antioxidant tris(nonyl phenyl) phosphate was prepared with nonyl phenol and phosphorus trichloride as raw materials, arene as solvent and by using directive esterification method.

2. The optimum technological conditions of nonyl phenolic resin modified by rosin have been studied.

3. In addition, nonyl phenol ethoxylate can be substituted with more biodegradable surfactants.

4. Experiments demonstrated that Anti-2- nonyl olefin aldehyde, furan aldehyde and 2-methyl aldehyde etc. had direct relation with aging flavor.

5. Stronger surfactants such as nonyl phenol ethoxylate have a better effect but they are more detrimental to the environment.

6. Reasonable result could be obtained by using water as dispersion medium, and nonyl hydroxybenzene polyethoxylate ether as dispersant but ultrasonic treatment was not preferred.

7. FEB desalting agent is a series of products from the polymerization of nonyl phenolic resin with epoxy ethane and epoxy propane.

8. Being an important raw material and intermediate in the fine petrochemicals industry, nonyl phenol has been developing at a relatively fast pace in foreign countries.

9. This paper describes a new method for synthesis of nonyl alcohol using pelargonic acid as starting material.
