Practical process for the air oxidation of cresols: Part A. Mechanistic investigations
Barton, Benita,Logie, Catherine G.,Schoonees, Barbara M.,Zeelie, Bernard
, p. 62 - 69 (2005)
The catalytic air oxidation of p-cresol and 2,6-di-tert-butyl-4- methylphenol to the corresponding benzaldehydes was investigated to determine the mechanism at work in these oxidation reactions. A number of intermediates and byproducts, mainly in the form of dimers, were observed during the course of the reactions, and their structures were elucidated by spectroscopic and chromatographic methods. The existence of these compounds in the reaction mixtures, and their proposed methods of formation, provided further insight into the mechanism involved in these oxidations.

, p. 1787 - 1789 (1997)
Products of thermolysis of 2,6-di-tert-butyl-4-dimethylaminomethylphenol were determined qualitatively and quantitatively by GLC, UV, and 1H NMR methods. The kinetics of the reaction was studied. The thermolysis products were studied as the inhibitors in thermopolymerization of monomers.

Paragraph 0001, (2017/07/20)
Antioxidant 1425 is an important chemical industry product. The basic process comprises a benzylation reaction, an alkaline hydrolysis reaction, and a complexing reaction. The production process comprises: pouring distillation kettle residue loaded into a barrel into a 2000 L enamel reaction kettle, maintaining a certain temperature (95-100 DEG C), slowly adding a prepared 2-5% sodium hydroxide solution according to a ratio of 1:1.1 under stirring, stirring for 2 h, carrying out standing layering, neutralizing the lower layer water phase, transferring into an antioxidant 1425 complexing kettle, mixing with the hydrolyzate in the production, extracting with solvent oil, recovering the small amount of the antioxidant 1425, and carrying out drying crystallization on the upper layer organic phase to obtain the product antioxidant 4426 product, wherein the main components of the dried waste gas are water vapor and a small amount of non-methane total hydrocarbons, and are subjected to unorganized emission.
