Abstract
Метод за получаване на метални хелати на лигниноцелулозна база, характеризиращ се с това, че лигниноцелулоза в раздробено и/или хидролизирано и/или изсушено състояние се окислява при 30 до 100'с в продължение на 0,5 до 12 часа с 4 до 12 об.части от 6 до 65%-на водна азотна киселина на 1 об. Част изходно сухо вещество и получената смес взаимодействува с алкални, борни, амониеви или алкалоземни соли, соли на металите от трета и четвърта преходна група и/или техни комплекси, които имат по-слаба стабилност отколкото съответният хелатен комплекс, респ. С техни смеси, или окислението се провежда в присъствие на посочените соли и/или комплекси. Патентните претенции са формулирани в 1 точка.A method for obtaining metal chelates based on lignin cellulose, characterized in that lignin cellulose in a crushed and/or hydrolyzed and/or dried state is oxidized at 30 to 100°C for 0.5 to 12 hours with 4 to 12 vol. .parts from 6 to 65% aqueous nitric acid per 1 vol. Part of the initial dry substance and the resulting mixture reacts with alkaline, boron, ammonium or alkaline earth salts, salts of the metals of the third and fourth transition groups and/or their complexes, which have a lower stability than the corresponding chelate complex, resp. With mixtures thereof, or the oxidation is carried out in the presence of the indicated salts and/or complexes. The patent claims are formulated in 1 point.
