Description
Азотна кислота споеебствует удалению лигнина из сырь и п Зё-веД&ййю окислительно-гидролитической деструкции целлюлозы , а сол на кислота уеКвр ёт: процеёе гидролитической деструкции и способствует получению более качественного продукта поNitric acid contributes to the removal of lignin from the raw materials and the production of oxidatively-hydrolytic degradation of cellulose, and hydrochloric acid, neEvr: the process of hydrolytic degradation and contributes to a better product
; цвету, так как образующийс хлор при смец1Йваний ебл ной и азотной кислот отбеливает гидроцеллюлозу. Уельвй опь1тов и технические показате5 ли порошковой целлюлозы из линта 3 сорта приведены в табл. 1 и 2.; color, as the chlorine formed during blending of nitrous and nitric acids bleaches the hydrocellulose. Welviente and technical indicators of 3rd grade lint cellulose powder are given in Table. 1 and 2.
Таблица 1Table 1
Вли ние концентрации кислот на продолжительность и делигнификацию сырь видно при сравнении опытов 1, 3, 5, 7, 9, 11, 13, 15. С увеличением концентрации кислот сокращаетс продолжительность с 3,6 до 1,0 ч, а содержание лигнйна снижаетс с 0,281 до 0,170%. Сол на кислота ускор етThe effect of acid concentration on the duration and delignification of the raw material can be seen when comparing experiments 1, 3, 5, 7, 9, 11, 13, 15. As the concentration of acids increases, the duration decreases from 3.6 to 1.0 h, and the lignin content decreases from 0.281 to 0.170%. Hydrochloric acid accelerates
Таблица 2table 2
варочно-гидролизующий процесс на 0,5- 1,5 ч.cooking-hydrolyzing process for 0.5-1.5 h.
В табл. 3 приведены сравнительные данные качественных показателей целевого продукта, полученного из линта 3 сорт-а по предлагаемому способу и по прототипу, а также целлюлозы, выпускаемой отечественной промышленностью.In tab. 3 shows the comparative data of quality indicators of the target product obtained from Lint 3 grade-a according to the proposed method and the prototype, as well as cellulose produced by domestic industry.
Предлагаемый способ позвол ет получить порошковую целлюлозу высокого качества непосредственно из низкосортного линта в одну стадию по упрощенной схеме.The proposed method allows to obtain high quality powdered cellulose directly from a low-grade lint in one stage in a simplified scheme.
Кроме того, способ вл етс технически более простым, так как позвол ет осуществл ть в одну стадию делигнификацию сырь и окислительно-гидролитическую деструкцию целлюлозы.In addition, the method is technically more simple, since it allows the delignification of the raw material and the oxidative-hydrolytic destruction of cellulose in one stage.
Потребность в электродной целлюлозе составл ет 2000 т в 1 год, экономи при замене пищевого продукта крахмала - 220 тыс. руб.The need for electrode cellulose is 2000 tons per year, saving up to 220 thousand rubles when replacing starch food.
