A process for the production of ethylene oxide, which comprises effecting ethylene oxidation with oxygen in the presence of carbon dioxide, the components being present in a volume ratio of 5-15 ethylene to 10-15 oxygen to 75-85, carbon dioxide. The process is effected at a temperature of from 290.degree. to 300.degree. C. and a pressure of from 35 to 50 atm. The components form an upward flow moving at a speed of from 10 to 12 m/sec. The oxidation is carried out in the presence of a silver catalyst on a carrier likewise forming an upward flow which moves at a speed of from 4 to 6 m/sec. The reaction mixture resulting from the oxidation procedure contains the desired product, the unreacted ethylene and the unreacted oxygen. The desired product is recovered from the mixture.

In accordance with the present invention, the process for preparing allyl chloride comprises chlorination of propylene with hydrogen chloride in an upward stream consisting of propylene, hydrogen chloride and a catalyst, i.e. manganese dioxide incorporated in a leaned manganese ore in an amount of 20 to 35% byu weight at a temperature within the range of from 300.degree. to 500.degree. C., concentration of the catalyst in the stream of 130-180 kg/m.sup.3, time of contact between propylene, hydrogen chloride and the catalyst in the stream of 0.2-0.7 sec and a volume ratio between propylene and hydrogen chloride in the stream of 1:3-5 respectively. Then the spent catalyst is separated from the reaction mixture resulting from chlorination, regenerated with oxygen at a temperature of from 500.degree. to 520.degree. C. and recycled to the chlorination process. The process according to the present invention makes it possible to achieve a yield of allyl chloride of up to 81.5 vol. % as calculated for the passed propylene, conversion of propylene of up to 98.0% at a process selectivity of from 80 to 85 vol. %. Furthermore, the process according to the present invention makes it possible to provide a wasteless production of allyl chloride.

In the reaction contrivance disclosed which serves the purpose of oxidizing hydrocarbons over a catalyst, with the catalyst being disposed in a casing of the contrivance. Next to an inlet into a reactor disposed in the casing, is a mixing chamber fitted rigidly, and linked with the casing of the contrivance. A separator is arranged at the outlet of the reactor. The mixing chamber provides a means of forming a reaction mixture of the reactants and the catalyst drawn from the casing and into the reactor. By virtue of this arrangement the entire surface of catalyst is in contact with the reactants and the yield of final product increases.
