Title: Improvements in the production of cellulose and cellulosic products
IPC: D21C1/02
Filed: 1934-05-16
Abstract: Cellulose particularly suitable for the production of cellulose esters and ethers or for the manufacture of paper, is prepared from wood, wood-pulp, straw and similar lignin-containing cellulosic materials by treatment with water or steam followed by treatment with nitric acid.  The first stage may comprise simple soaking in cold or warm water; or the materials may be treated with boiling water or wet steam especially at temperatures above 100 DEG  C., for example, up to 150 DEG  C.  For the acid treatment there may be used concentrations up to 20 per cent in the cold or at moderate temperatures or at the boil; preferably the conditions set out in Specification 438,435 are employed, for example, 2--10 per cent acid at 70--95 DEG  C.; and the acid may contain a wood constituent as described in Specification 438,433.  The nitric acid may be produced in situ, as by impregnating the material with a solution of a soluble nitrate, drying, and then treating with mineral acid; conveniently, the water employed in the first stage of the treatment may contain the necessary nitrate. Extraction with alkali may follow the nitric acid treatment, and such alkali extraction may involve treatment with cold, moderately strong alkali or with hot or boiling alkali of lower concentrations without pressure or with pressure even at a pressure of 6--10 atmospheres in excess of that corresponding with the temperature employed; alternatively, the material may be first treated with dilute alkali at elevated temperatures and then with cold more concentrated alkali.
