The aim of the project is to develop effective methods and technologies for obtaining derivatives of the furan series and new organic materials based on 5-hydroxymethylfurfural (5-HMF) from renewable raw materials of plant origin. Solving this problem requires studying the fundamental regularities of catalytic processes with the participation of a chemically complex raw material - plant biomass and creating on its basis environmentally friendly technologies for the production of substances and materials that meet the concept of a "zero" carbon cycle. At the previous stages of research, catalytic systems and technological foundations for the processing of hexose plant materials into 5-HMF and subsequently into furandicarboxylic acid (FDCA) were developed; automated laboratory facilities for the synthesis of these important furan derivatives have been developed and created; a number of new furan monomers and polymers have been obtained, the operational properties of products from which determine broad prospects for their application; approaches to utilization of by-products and wastes of catalytic processing of plant biomass are proposed. This project will continue the development of new functionalized derivatives of 5-HMF - FDCA esters; new furan monomers and polymers, as well as biodegradable composites based on furan polymers and metal oxides; their properties are investigated and the prospects for production and application are evaluated. New methods will be developed, including electrochemical ones, for the synthesis of new monomers and polymers based on furan compounds. Work will continue on creating a set of equipment (automated laboratory facilities) and optimizing the parameters for the synthesis of furan polyesters directly from renewable plant materials, including technologies for waste disposal and wastewater treatment, which will allow developing approaches to the industrial scaling of technologies for the efficient processing of renewable plant materials into valuable products and materials .
