METHODS OF MODIFICATION OF HYDROCARBONS LIQUID PHASE OXIDATION

Abstract: it gives a short description of influence of the catalysts, polar solvents, reaction duration, temperature, pressure, hydrocarbons concentration in the reaction mixture, oxygen concentration in the oxidating gas, addition of water into the oxidation zone, removal of the reaction products out of the oxidation zone, step-by-step temperature change in the oxidation zone, step-by-step introduction…

MODIFICATION OF THERMOPLASTIC POLYMERS

 Synopsis: Modification of thermoplastic polymers (polystyrene, vinyl acetate, polyacrylates, polyvinyl chlorides) by introduction of oxygen or oxygen containing gas (air) into monomer polymerization zone and heating of the peroxicontaining polymer which is being formed to 110-180 o C. The ways of utilization of modified polymers to produce electric insulating, thermo insulating and soundproof materials, construction,…

A NEW METHOD OF THE PRODUCING OF ACETIC, FORMIC AND PROPIONIC ACIDS BY LIQUID-PHASE OXIDATION OF LIGHT HYDROCARBON FRACTIONS

The requirements in lower carboxylic acids: acetic, formic and propionic were given. The mechanism of liquid-phase oxidation of n-pentane was proposed. The main directions of the formation of the oxidation products of n-pentane were illustrated. Based on a study of the reaction mechanism and the influence of the main process parameters on the yield of…
