Hydroperoxide reduction production technology

Abstract

The invention provides a new hydroperoxide production technology using a reduction reaction. The technology is a multi-stage reduction technology, and comprises a two-stage reduction reaction step, wherein a first-stage reduction reaction treats a diisopropylbenzene oxidation liquid and a water phase generated in a second-stage reduction reaction as raw materials, and the second-stage reduction reaction treats an organic phase generated in the first-stage reduction reaction and a reducing agent as raw materials. Compared with original technologies, the technology provided by the invention has the advantages of substantial reduction of the consumption of the reducing agent, reduction of above 30% of reducing wastewater, reduction of about 50% of the content of sulphions and thiosulfate ions in wastewater, realization of biochemical treatment of wastewater which cannot be biochemically treated originally, and generation of a very small amount of hydrogen sulfide and sulfur after the wastewater treatment. The technology provided by the invention allows the hydroperoxide content at the end point of the reduction reactions and the quality requirement of reducing liquids of the original technologies to be realized.

Description

technical field [0001] The invention relates to a reduction process, in particular to a new process for the reduction production of hydroperoxides. Background technique [0002] BIPB is the abbreviation of bis-(tert-butylperoxyisopropyl)benzene. It is an upgraded product of dicumyl peroxide (DCP), commonly known as "odorless DCP". agent. The BIPB market has great potential. Since BIPB has been in short supply in domestic and foreign markets for a long time, it is foreseeable that with the development of international market globalization, the enhancement of people's environmental protection awareness and the improvement of life quality, the demand for BIPB by domestic and foreign users will increase. more and more. [0003] The reduction process is an important part of the BIPB production process, that is, the diisopropylbenzene (DIPB) oxidation solution (obtained from the oxidation of dicumene) is reduced with a reducing agent, and the intermediate di-(2-hydroxy-isopropyl...

AI Technical Summary

Problems solved by technology

Various methods such as inorganic salt precipitation, air oxidation, and hydrogen peroxide oxidation were tested to treat reduced wastewater, but the effect was not good.

The combined process of acid decomposition-Fenton oxidation has a certain effect on the treatment of reduced wastewater, but the hydrogen sulfide, sulfur dioxide, and sulfur produced at the same time require high wastewater treatment.
