Abstract

PURPOSE: To economically manufacture the above mentioned chemicals with high yield, by hydrolyzing 1-acyloxy-3,4-dialkoxybenzene obtained by electrolyzing 1,2- dialkoxybenzenes in nitrile and amido or ketone at the presence of organic carboxylic acids (salts).
CONSTITUTION: 1,2-Dialkoxybenzenes (for example; 1,2-dimethoxybezene) having C1W4 alkoxy radical, are electrolyzed in nitrile, amide or ketone under the existence of organic carboxylic acid (salts), such as acetic acid (salt) etc., at the condition, temperature; 10W100°C (suitably 20W50°C) current density; 5W200mA/cm2 (10W 100mA/cm2). Next, obtained 1-acyloxy-3,4-dialkoxybenenes are hydrolyzed at 20W 200°C (suitably 50W100°C) at the presence of basic or acidic catalyst. The above mentioned product is utilized for intermediates for manufacturing compounding agent for medicine.agricultural chemicals.synthetic resin.
