Oxidation is the interaction of oxygen molecules with various substances. This is one of the main processes that exist on Earth. This phenomenon exists both in living and non-living nature. It is customary to refer the oxidation process to chemical processes. It is also found in other processes, in particular, biological. Oxidation of compounds in…
Despite the need and the cost of oil, it was, is and will be one of the main sources of energy and the main raw material for obtaining various household and industrial products. In the world there are various types of energy, in particular, the energy of the sun, water, wind and cold thermonuclear fusion….
Humanity’s concern for the future is a very noble cause. Therefore, particular attention is paid to the activities of various environmental movements. In particular, the movement which is engaged in the reduction of carbon dioxide emissions into the atmosphere. It must be borne in mind that the activities of mankind significantly affect the environmental situation…
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…
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,…
The oil sands are one of the oil sources. They consist of sand and clay saturated with medium and heavy hydrocarbons. Depending on the field the mass fraction of hydrocarbons in the oil sands may range from a few percent to several dozens percent. In general, the mass fraction of oil in the oil sands…
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…
