Microwave-hydrothermal method for synthesizing acetylated wood

The invention discloses a microwave-hydrothermal method for synthesizing acetylated wood, and the method disclosed by the invention is little in dosage of acylating agent, simple in process, short in reaction time, high in efficiency, cheap in cost and friendly to environment. The microwave-hydrothermal method for synthesizing acetylated wood comprises the following steps of: step 1, mixing and stirring wood with acetylated fluid for 10-30 minutes under 10-100 DEG C according to a mass ratio of 1-10:100 so as to obtain precursors of a microwave-hydrothermal reaction, wherein the weight percentage of water content to the wood is 6%-20%; step 2: putting the precursors obtained in the step 1 into a polytetrafluoroethylene-lined reaction kettle, and putting the reaction kettle into a microwave-hydrothermal reaction instrument to carry out acetylation; and step 3, after finishing the acetylation, cooling the reaction kettle to room temperature, taking out solids in the reaction kettle, and putting the solids into
