摘要：
Abstract: We present a laboratory study confirming that phenol in phenol–formaldehyde resins can be replaced with deep thermal-processing products of raw wood. Operating conditions of synthesis are described, and a synthetic recipe is given. The synthesized resins were analyzed by physicochemical methods (IR spectroscopy, TGA, and the tensile strength test). The study revealed that such a replacement requires no considerable changes to be made in operating parameters of the current synthetic process for phenol–formaldehyde resins and allows one to obtain a glue based on this resin with a shear strength equal to 1.58 MPa, which meets specifications of the state standard. © 2023, Pleiades Publishing, Ltd.
