Abstract

1.СПОСОБ ПОЛУЧЕНИЯ ОРГАНОМИНЕРАЛЬНОГО УДОБРЕНИЯ НА ОСНОВЕ ЛИГНИНА нитрационным окислением азотной кислотой с последующей нейтрализацией кислых продуктов, отличающийс  тем, что, с целью упрощени  процесса и повышени  суммы питательных веществ в конечном продукте, нитрационное окисление лигнина ведут азотной кислотой в момент ее образовани , выдел ющейс  при взаимодействии смеси порошкообразных лигнина и калиевой селитры в соотношении 1:1. THE METHOD OF OBTAINING ORGANOMINERAL FERTILIZER BASED ON LIGNIN by nitration oxidation with nitric acid followed by neutralization of acidic products, characterized in that, in order to simplify the process and increase the amount of nutrients in the final product, nitration acidification of lignin leads to nitric acid at the time of its formation, releasing nitric acid when interacting a mixture of powdered lignin and potassium nitrate in a ratio of 1:
