Cyclic sulfate and preparation method thereof

Abstract

The invention relates to cyclic sulfate and a preparation method thereof. According to the method, the cyclic sulfite is oxidized under the action of hydrogen peroxide under the catalytic action of the boron-containing molecular sieve to obtain the cyclic sulfate, the cyclic sulfate product obtained by the method is high in purity and low in acidity, and the boron-containing molecular sieve can be recycled; and on the other hand, in the synthesis process of the cyclic sulfate, no high-salinity wastewater is generated, the whole synthesis process is green and environment-friendly, the used solvent is single, the reaction is mild, the steps are simple, the cost is low, and the method is suitable for large-scale industrial production.
