FIELD: chemical industry; production of hydrogen peroxide and oxiranes.
SUBSTANCE: the invention is dealt with a method of production of hydrogen peroxides and oxiranes. The invention provides for conductance of reaction of olefin with hydrogen peroxide at the presence of a catalyst and organic thinner. At that hydrogen peroxide is present as a water solution of hydrogen peroxide extracted mainly with the help of purified water out of a mixture produced as a result of oxidation at least of one alkylanthrahydroquinone without aftertreatment with a cleansing water and-or purification. The technical result is an increase of an output and selectivity of oxirane.
EFFECT: the invention ensures increased output and selectivity of oxirane.
