METHOD FOR PRODUCING ORGANIC NITRO COMPOUNDS Russian patent published in 2017 - IPC C07C201/02 C07C203/04 C07C241/00 C07C243/02 C07D233/02 C07D239/04 C07D493/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the organic nitro compound chemistry and specifically to a process for producing nitro compounds of the general formula of RNO₂, where R=n-C₄H₉O-; O₂NO(CH₂)₂O-; O₂NO(CH₂)₂O(CH₂)₂O-; O₂NOCH₂CH(ONO₂)CH₂O-; (O₂NOCH₂)₃CCH₂O-; where m=1, 2; where n=2, 3; , which can find application in producing high-energy products, medicines, dyes, polymers, etc. The method consists in the fact that the corresponding alcohols or amines derivatives are subject to nitration with nitric oxide (V) or its mixture with 100% nitric acid in a medium of lower hydrofluorocarbons, the process is carried out at a pressure of 3-60 bar and a temperature of 5-40°C at a molar ratio of the corresponding starter compound and nitrating agent 1:(1.1-4.4).

EFFECT: method allows to reduce fire and explosion hazard of the process, improve its environmental performance and obtain the desired compounds with high output.
