Investigation of Various Stages Process for Producing Microcrystalline Pulp from Hemp for its Quality Indicators

A comparative analysis of the chemical composition of the hemp fibers and stalks with cotton and representatives of hardwood and softwood was performed. The possibility of obtaining microcrystalline cellulose from hemp fibers by alkaline sulfite-alcohol delignification with preliminary acid and alkaline hydrolysis was investigated. It was found that carrying out an acid and an alkali pre-hydrolysis reduces the mineral content and partly of residual lignin in the plant material.
