METHOD FOR PRODUCING 5(6)-NITRO-1-(4-NITROPHENYL)-1,3,3-TRIMETHYLINDANES Russian patent published in 2015 - IPC C07C201/08 C07C205/06 B01J21/12 B01J27/53 B01J27/12

Abstract RU 2551672 C1

FIELD: chemistry.

SUBSTANCE: invention refers to a method for producing 5- and 6-nitro-1-(4-nitrophenyl)-1,3,3-trimethylindanes by carrying out a reaction of 1,1,3-trimethyl-3-phenylindane and nitric acid. According to the present method, 1,1,3-trimethyl-3-phenylindane is nitrated in the presence of a catalyst - modified amorphous mesoporous aluminium silicate (fluorinated or sulphated). The reaction is carried out at 80-130°C and molar ratio of phenylindane:HNO₃ = 1:6÷14 for 8 h in the presence of 2-4 wt % (at the reaction mixture) of the catalyst.

EFFECT: method enables discarding sulphuric acid in the nitration process, as well as simplifying the process and reducing its price.
