Abstract
Major characteristics of cellulose obtained from fruit shells of oat by the hydrotropic method were studied. It was demonstrated that bleaching of technical cellulose sample contributed to cellulose concentration and the removal of the bulk of noncellulosic compounds in the product. Samples of esters close by major characteristics to mastic-lacquer colloxylins were synthesised under conditions of preparation of highly soluble cellulose nitrates. Cellulose fibres of fruit shells of oat and cellulose nitrates obtained were characterized by scanning electron microscopy (SEM) techniques. It was found by IR spectroscopy that hydrotropic cellulose was identical to cellulose from traditional types of plant raw materials by major adsorption bands. It was demonstrated that the resulting esters were cellulose nitrates.
