Wood as chemical raw material. History and modernity. V. Wood pulp as natural polymer raw material. Part I

The history of chemical processing development of the improved technical wood cellulose for the receiving of the additive derivatives, complex and simple ethers on their basis are considered. The historical transformation of technologies for the production of plant parchment, fiber, copper-ammonia fiber, synthesis of cellulose nitrates, xanthogenates and acetates, as well as methods for processing these derivatives into target products and materials is described in detail. The historical description of the preparation and prospects for the use of cellulose esters and modification of cellulose fiber hydrate is given. This article is the fifth in the cycle «Wood as a chemical raw material. History and modernity»; the previous parts were published in the journal Lesnoy vestnik / Forestry Bulletin (2020, v. 24, no 1, № 5; 2021, v. 25 no. 3; 2022, v. 26 no. 1).
