| abstract | OnenProcess for the preparation of 3,4-diisopropoxynitrobenzene, characterizedncharacterized in that 1,2-diisopropoxybenzene with a mixture ofn20 to 60 wt .-% nitric acidnand 40 to 98 wt .-% sulfuric acid is reacted, and anProcess for the preparation of 1,2-diisopropoxybenzene, characterizednthat 2-isopropoxyphenol and isopropyl bromide with aqueousnAlkali hydroxide and a tetraalkylammonium halide are reacted,nthe initial molarnrelationshipnof isopropyl bromide to 2-isopropoxyphenol is 2 to 10ncharacterized by the fact that they are both the intermediate 1,2-diisopropoxybenzene asnalso the end product 3,4-Diisopropoxynitrobenzol in very pure conditionnand high yield and also with cost-effective feedstocksnand inexpensive work-up techniques can be performed. |
