METHOD OF GRAIN-SIZE ANALYSIS OF LIGNOCARBOHYDRATE MATERIALS

摘要

FIELD: chemistry. ^ SUBSTANCE: method of a grain-size analysis of lignocarbohydrate materials is based on a direct optical technique of the computer analysis of the plotting in which make measurements of a mass fraction and the square of corpuscles by means of the program of grain-size analysis. For conducting of measurements the corpuscle of comminuted lignocarbohydrate materials is inducted into organic solvent, put in the form of the suspension preliminarily processed by ultrasound, on glass, cover with other glass and put on the cleared surface of the scanner. For a grain-size analysis in addition the extent of destruction of an investigated material is defined. ^ EFFECT: creation of the method, that allow to obtain more precise information about the corpuscles' form and sizes of lignocarbohydrate materials; to predict properties of products gained during chemical transformations. ^ 2 dwg
