Production process for NECONOX 1300
NECONOX 1300 is the intermediate chemical for production of phenolic antioxidants, i.e. NECONOX 1010 and NECONOX 1076. The chemical structure of NECONOX 1300 is illustrated in the following figure. It is worth noting that NECONOX 1300 is also an antioxidant.

The chemical structure of NECONOX 1300
NECONOX 1300 is produced via chemical reaction between 2, 6-di-tert-butylphenol and methyl acrylate in the presence of a phenolate catalyst. The catalyst is manufactured from the reaction of 2, 6-di-tert-butylphenol with sodium and potassium hydroxide.

The chemical structure of methyl acrylate

The reaction lasts several hours to complete. The raw NECONOX 1300 which is extracted from the reactor is light yellow and freezes below 120 °C. These materials contain impurities such as unreacted raw materials and some heavy compounds. Vacuum distillation is normally used for purification of raw NECONOX 1300. The purity of the NECONOX 1300 can reach 99% or more which is suitable for producing NECONOX 1010 and NECONOX 1076.
