METHOD FOR PRODUCING 1-NITRONAPHTHALENE Russian patent published in 2018 - IPC C07C201/08 C07C201/16 C07C205/06 

Abstract RU 2669774 C1

FIELD: biotechnology; technological processes.

SUBSTANCE: invention relates to organic synthesis and relates to processes for the preparation of 1-nitronaphthalene. Object of the invention is to carry out nitration in homogeneous conditions. 1-nitronaphthalene is formed by the reaction of naphthalene dissolved in dioxane with a nitrating mixture consisting of concentrated sulfuric and concentrated nitric acids. Nitration is carried out with stirring and heating in a boiling water bath for 40–60 minutes. Yield of 1-nitronaphthalene reaches 97 % of the theoretical yield.

EFFECT: proposed solution allows for synthesis under homogeneous conditions.
