  • Scalable Method for Preparing Crystalline Borosulfate Materials
    Publication number: 20230249978
    Abstract: A method of preparing borosulfate materials avoids the need for fuming sulfuric acid, also known as oleum. Instead, B(OH)3 present in solution in concentrated sulfuric acid at 5% to 15% by weight is reacted with a cation source at 100-250° C. under dynamic vacuum while in connection with a receiving vessel comprising a desiccant and separate from the reaction vessel, thereby causing formation of a borosulfate material in the reaction vessel while eliminated water is collected in the receiving vessel.
