Abstract
Un procedimiento para preparar productos de reacción parciales purificados de los 1.5 dinitro-benzol sustituido en posición 2 por un grupo alkiloxi o alkenoloxi, pudiendo introducirse este grupo antes o despues de la reducción; caracterizado porque la mezcla de isómeros resultante de la reducción se disuelve en un disolvente orgánico y se trata con un absorbente que retenga los isómeros menos fuertemente que las demás sustancias presentes, y por adición de un ácido, con preferencia practicamente anhidro al filtrado, precipita una sal de las sustancias deseadas dificilmente soluble en disolventes orgánicos.A process to prepare purified partial reaction products of the 1,5 dinitro-benzol substituted in position 2 by an alkyloxy or alkenoloxy group, this group can be introduced before or after reduction; characterized in that the mixture of isomers resulting from the reduction is dissolved in an organic solvent and treated with an absorbent that retains the isomers less strongly than the other substances present, and by adding an acid, preferably practically anhydrous to the filtrate, precipitates a salt of the desired substances hardly soluble in organic solvents.
