Deykun I. Development of technologies of reception of flax cellulose for chemical procissing

Process of delignification waste products of processing of flax (a short fibre) soda method and soda method with preliminary water and acid hydrolysis is investigated.Influence actions anthraquinone on delignification of soda method flaxes waste products is investigated.The was calculated kinetic parameters of delignification the soda method of flaxes waste products.The opportunity of reception of flax cellulose for chemical processing by neutral - sulphite and monosulphite methods was investigated. Action of bleaching reagents on nonbleaching flax cellulose is investigated. Schemes of bleaching flax cellulose which provide necessary quality of cellulose are developed.The fractional structure on average degree of polymerization bleaching and nonbleaching flax cellulose is investigated.Suitability of flax cellulose for manufacture varnish colloxylin is investigated. Basic technological schemes of pulping of waste products of processing of flax by soda, soda with prehydrolysis and monosulphitic method,and also without chlorine scheme bleaching of flax cellulose and without use of molecular chlorine are offered.
