Abstract

Способ получения 3-алкиламинобензантрона обработкой бензантрона, замещенного в положении 3, алкилирующим агентом при повышенной температуре, отличающийся тем, что, с целью повышения выхода целевого продукта, упрощения технологического процесса и расширения ассортимента алкилпроизводных 3-аминобензантрона, в качестве исходного соединения берут 3-аминобензантрон, в качестве алкирующего агента - триалкилфосфат с числом углеродных атомов в алкильном остатке 1÷4, при их мольном соотношении 1:10÷20 соответственно, и процесс ведут при 160-170°С в течение 10-15 часов для получения 3-моноалкиламинобензантрона, или при 190-200°С в течение 5-6 часов для получения 3-диалкиламинобензантрона.The method of obtaining 3-alkylaminobenzene by treating benzantrone, substituted in position 3, with an alkylating agent at elevated temperature, characterized in that, in order to increase the yield of the target product, simplify the process and expand the range of alkyl derivatives of 3-aminobenthrone, 3-aminobentanthrone is taken as the starting compound , as an alkylating agent, is a trialkyl phosphate with the number of carbon atoms in the alkyl residue 1 ÷ 4, with a molar ratio of 1: 10 ÷ 20, respectively, and the process is carried out at 160-170 ° С in those 10-15 hours to obtain 3-monoalkylaminobenzantrone, or at 190-200 ° C for 5-6 hours to obtain 3-dialkylaminobenzantrone.
