REACTOR OF PARAXYLOL OXIDATION FOR OBTAINING TEREPHTHALIC ACID Russian patent published in 2014 - IPC C07C51/265 B01J8/22 C07C63/26 

FIELD: chemistry.

SUBSTANCE: reactor contains reactor case, and device of air input of distribution type and device of air input of cyclone type are located in lower parts of reactor case, device of air input of distribution type contains a series of tubes of air distribution, and device of air input of cyclone type consists of several tubes of cyclone air input, located below tubes of air distribution, with segment of air output of said tubes of cyclone air input being inclined at 45-60° relative to reservoir case radius. Application of combined device of air input can make liquid at the bottom of reactor rotate under pressure of proper amount of air, in addition reactor has good air dispersion, in such way, preserving materials in suspended state.

EFFECT: reactor improvement.
