Получение целлюлозы щелочно-окислительно-органосольвентным способом

Получение целлюлозы щелочно-окислительно-органосольвентным способом

Abstract

Possibility of receiving cellulose from a waste of processing of not wood vegetative raw materials – straw and oats peel – step way, where the first step – alkaline, the second – oxidation-organosolvent in the presence of ozone is investigated. The chemical composition of initial vegetative raw materials and its anatomic structure is studied. Conditions of carrying out each step of cooking – duration, cooking temperature, a consumption of cooking reagent are investigated, and their optimum values are established. The analysis of properties of the received technical cellulose is carried out, is established that the technical cellulose received in the course of a delignification possesses high indicators of sorbtsionny ability, a whiteness. It allows to recommend it for use as valuable raw materials for production of products of the cosmetic, pharmaceutical and food industry.

Исследована возможность получения целлюлозы из отходов переработки недревесного растительного сырья – соломы и шелухи овса – ступенчатым способом варки, где первая ступень – щелочная, вторая – окислительно-органосольвентная в присутствии озона. Изучен химический состав исходного растительного сырья и его анатомическое строение. Исследованы условия проведения каждой ступени варки: продолжительность, температура варки, расход варочного реагента, и установлены их оптимальные значения. Проведен анализ свойств полученной технической целлюлозы,установлено, что полученная в процессе делигнификации техническая целлюлоза обладает высокими показателями сорбционной способности, белизны. Это позволяет рекомендовать ее к использованию в качестве ценного сырья для производства продуктов косметической, фармацевтической и пищевой промышленности.
