摘要：
Abstract: This paper presents a scheme for fractionation of liquid pyrolysis products of birch sawdust to obtain a carbohydrate fraction and its use as a biopolyol in the production of polyurethane foam. GCMS analysis and IR spectrometry of biopolyols were carried out. Samples of polyurethane foam with particular replacement of 20, 30, and 40% biopolyol were obtained. Thermal conductivity of the obtained polyurethane foam samples was measured. The results of the work carried out allow it to be concluded that reactive OH groups are present in the carbohydrate fraction and the biopolyols from pyrolysis liquid of birch sawdust can be used in the synthesis of hard polyurethane foams. © 2022, Pleiades Publishing, Ltd.
