Description
личества. Получают 2,50 г кислоты (90,2% от теоретического) с т. пл. 237-237,5°С. Пример 3. Процесс провод т так же, как в примере 2, но загружают 10 г 2-метил5-этилпиридина , 105 мл 75%-ной серной кислоты , 0,8 г хлорида марганца и 0,45 г хлорида хрома. Получают 12,8 г изоцинхомероновой кислоты (92,6% от теоретического) с т. пл. 237-237,5°С. Предмет изобретени Способ получени изоцинхомероновой кислоты окислением 2-метил-5-этилпиридина в присутствии катализатора, отличающийс тем, что, с целью упрощени процесса , окисление провод т озоно-кислородной смесью, а в качестве катализатора используют соли т желых металлов, например соль хрома или марганца.lichkoy. Get 2.50 g of acid (90.2% of theoretical) with so pl. 237-237.5 ° C. Example 3. The process is carried out as in Example 2, but loading 10 g of 2-methyl 5-ethylpyridine, 105 ml of 75% sulfuric acid, 0.8 g of manganese chloride and 0.45 g of chromium chloride. Obtain 12.8 g of isozinchomeronic acid (92.6% of theoretical) with m. Pl. 237-237.5 ° C. The subject of the invention is a method for producing iso-zincomeric acid by oxidation of 2-methyl-5-ethylpyridine in the presence of a catalyst, characterized in that, in order to simplify the process, the oxidation is carried out with an ozone-oxygen mixture, and salts of heavy metals, for example, chromium or manganese.
