-
Paragraph 0073-0074, (2020/09/23)
The invention belongs to the technical field of organic synthesis, and particularly relates to a preparation method and application of a cyclic sulfate compound. One embodiment of the invention provides a preparation method of a cyclic sulfate compound. The cyclic sulfate compound is prepared from a compound A and sulfur-containing oxide, wherein the structural formula of the compound A is shown in the specification, R is selected from one of H, alkyl, alkenyl, substituted alkyl, aryl and halogen, X is C or S, and Y is-CH2-CH2-or-CH = C-. The compound A and sulfur trioxide are reliable in source, low in price, mild in reaction condition, easy to operate, free of waste water in the reaction process, few in three wastes, good in product quality, suitable for large-scale production, capable of obtaining the high-purity battery-grade ethylene sulfate compound, and relatively high in implementation value and social and economic benefits.

A copper metal–organic hydrogel (MOG) has been synthesized using an amino acid-based ligand, Na2HL {H3L = 2-{(3,5-di-tert-butyl-2-hydroxybenzyl)amino succinic acid} as a gelator. The metallohydrogel exhibits pH-responsive nature as well as chemical responsiveness. Besides, it shows rapid thixotropic behavior when external mechanical forces are applied. The metal–organic hydrogel can be used as a heterogeneous catalyst for the reaction of SO2 and CO2 with epoxides to produce cyclic 1,3,2-dioxathiolane-2-oxides and carbonates, respectively. The conversions were found to be dependent on the size and type of the side chain of the epoxides.
