Abstract

Способ получения 6-алкокси-3-метилфеналенонов общей формулыгде R - метил или этил,из 1-алкоксинафталина общей формулыгде R имеет вышеуказанное значение, отличающийся тем, что, с целью увеличения выхода целевого продукта и упрощения технологии процесса, 1-алкоксинафталин конденсируют с ацетоуксусным эфиром при молярном соотношении 1-алкоксинафталин - ацетоуксусный эфир 1:1,0-1,2 в среде 82-94%-ной серной кислоты, прибавление которой проводят при 0-10°С с дальнейшим проведением процесса при температуре 15-35°С.The method of obtaining 6-alkoxy-3-methylphenalenones of the general formula where R is methyl or ethyl, from 1-alkoxynaphthalene of the general formula where R has the above value, characterized in that in order to increase the yield of the target product and simplify the process, 1-alkoxynaphthalene is condensed with acetoace ether at a molar ratio of 1-alkoxynaphthalene - acetoacetic ester 1: 1.0-1.2 in an environment of 82-94% sulfuric acid, the addition of which is carried out at 0-10 ° C with further process at a temperature of 15-35 ° C .
