Abstract

This invention discloses a bio-based monomer containing an acetal structure and its preparation method. The chemical name of the monomer is 5-ethyl-2-(5-hydroxymethyl-2-furan)-1,3-dioxane-5-methanol. The preparation method involves the acetalization reaction of 5-hydroxymethylfurfural with trimethylolpropane. The monomer of this invention is synthesized based on 5-hydroxymethylfurfural, representing a novel type of acetal ring and enriching the chemical diversity of acetal rings. Furthermore, 5-hydroxymethylfurfural can be obtained from biomass such as fructose, making it a low-cost, renewable bio-based raw material that reduces dependence on petroleum-based feedstocks. In addition, the preparation method of the bio-based monomer containing an acetal structure of this invention features a simple and easy-to-operate process, mild reaction conditions, environmentally friendly and inexpensive raw materials, simple purification methods, high yield, and low equipment requirements, making it suitable for large-scale production.
