Production of cellulose-containing intermediates from the wood of broad-leaved and coniferous species using its treatment under the conditions of explosive autohydrolysis
Chemistry of Natural Compounds - Tập 34 - Trang 643-646 - 2013
A. A. Efremov, I. V. Krotova
The influence of the technological parameters of the process of explosive autohydrolysis of the wood of aspen, pine, and spruce on the yield and composition of cellulose-containing intermediates has been studied. It has been established that with a rise in temperature and an increase in the time of explosive autohydrolysis the yield of technical cellulose falls and the content of Kürschner cellulo...... hiện toàn bộ
