Microstructural reactors: Concept, development and application

In the recent years owing to growing necessity of raw material and energy economy and solution of ecological problems, a significant interest by the chemistry thechnologists is paid to the microsystem technology. One of directions in the development of microsystem technology is creation and application of microstructural reactors (microreactors). Currently world market proposes many samples of microstructural installations and even full-value chemical units for, in part, of organic synthesis. In Russia the microsystem technology is included to the list of priority directions of development of science and technology in 2001–2010 years.     

Perspectives of heterogeneous process intensification in microreactors

Recent developments in microreactor technology basing on different types of heterogeneous reaction systems: phase transfer catalysis, biocatalysis, and synthesis of nanoparticles are reviewed. Special attention is focused on the intensification of processes in microreactors compared with traditional approaches, which makes microtechnique of great interest for industry.     

Synthesis of perfluoronitromethanes

Conclusions Perfluoronitromethanes can be prepared by fluorinating the potassium salt of nitroform with elemental fluorine. The ratio between the amounts of fluoronitroform and difluorodinitromethane formed depends on the reaction conditions and can be controlled.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimiicheskaya, No. 2, pp. 429–430, February, 1968.
