Abstract
Методът се прилага в химическата промишленост. Той е икономичен и екологично чист. По метода алкален воден разтвор на лактоза и боракс се приготвя и нагрява при температура над 800с. Лактулозата се отделя от получените продукти на конверсия, като към разтвора не се прибавя друг алкализиращ продукт освен боракс. Конверсията се провежда при рн 8,3. С цел да се запазят натриевите йони в производствения цикъл, бораксът се получава във воден разтвор на борна киселина, успоредно с лактозата. Натриевите йони се прехвърлят от разтвора на конверсните продукти в разтвора на борната киселина чрез електродиализа. 6 претенции
