This utility model discloses a compartmentalized spray water cup, relating to the field of water cups. It includes a drinking cap rotatably mounted on the upper end of a connecting cap. The connecting cap houses a drinking compartment and a spray compartment. A spray cap module is located at the upper end of the spray compartment. An auxiliary locking mechanism is provided between the spray cap module and the connecting cap, allowing for quick disassembly of the spray cap module. This compartmentalized spray water cup separates the drinking and spraying functions, enabling independent control and preventing both functions from sharing a single compartment, thus avoiding contamination of the compartment's interior. This achieves cleaner and more convenient use of both the spray and drinking functions. The spray cap module is detachable, engaging with the spray switch button via a latch located at the rear of the spray module. This allows for easy removal of the spray cap module and spray nozzle, achieving low-cost replacement of easily damaged spray heads and reducing after-sales costs.

The application belongs to the technical field of organic synthesis, and particularly relates to selective oxidation of thioether to prepare sulfoxide and sulfone by using zirconium hydroxide as a catalyst. The application uses thioether as raw material, zirconium hydroxide as catalyst, and hydrogen peroxide as oxidant. Sulfoxide can be catalytically oxidized and synthesized in a short reaction time, and sulfone can be obtained by prolonging the reaction time. The selectivity can be regulated only by the reaction time without any additives. The zirconium hydroxide catalyst can be directly purchased or prepared by using a simple precipitation method with zirconium salt as a precursor, and is low in price. Hydrogen peroxide is used as an oxidant, and is green, stable, low in cost, high in atomic efficiency (47% active oxygen), and has water as the only by-product. In addition, the reaction process is simple in operation, low in cost, and high in yield, and has great industrial application prospect.
