Title:
METHOD OF OBTAINING BROMATED AROMATIC AND HETEROCYCLIC COMBINATIONS CONTAINING ACCEPTOR GROUPS
Document Type and Number:
WIPO Patent Application WO/1990/007479
Kind Code:
A1
Abstract:
A method of obtaining bromated aromatic and heterocyclic combinations containing acceptor groups provides for bromination of aromatic and heterocyclic combinations, containing acceptor groups, with bromine or hydrobromic acid, the process being carried out in the presence of sulphuric acid or oleum in combination with nitric acid or its salts at a temperature of 20-120�C at the following molar ratio of the reagents per mol of the initial compounds: bromine 0.5-3.2 or a salt of hydrobromic acid 1.0-7.0, nitric acid 0.5-3,0 or a salt of nitric acid 1.4-4.0, sulphuric acid or oleum 6.0-70.0. The obtained combinations may be used as antipyretics, as intermediate products in synthesis of dyes, pigments, herbicides and for other purposes.
