The influence of the main process parameters (temperature, duration, irrigation modulus, catalyst content) alkaline and acid treatment of flax fibers on the quality parameters of the obtained pulp was investigated. The effect of various chemical agents on removing non-cellulose components of flax fibers, in particular minerals, was studied. It was found that during alkaline treatment of the flax fibers sodium hydroxide better removed lignin and minerals than potassium hydroxide and hydrous ammonia.For the production of microcrystalline cellulose of flax fibers, it is recommended to carry out alkaline treatment at the concentration of sodium hydroxide in 20-25 % solution at the temperature of 160 0С for 180 minutes.The preliminary stage of a...
