This invention discloses a highly efficient composite solubilizer for the hydration of butene to sec-butanol, belonging to the field of chemical process technology. Its composition includes: 0-60 parts of a polyether-based polymeric surfactant, 15-35 parts of a highly polar aprotic solvent, and 10-20 parts of a co-catalyst. The main solubilizing component of this invention disperses oily butene into extremely small droplets, allowing it to mix uniformly in water, thereby increasing the surface area for the reaction. The co-solvent, as the main component, provides a stable environment, ensuring that this highly mixed state is maintained for a certain period. The added additives, possessing both water and oil solubility, facilitate smoother dissolution of the mixture and help the reactants quickly contact the active sites of the catalyst. This accelerates the reaction rate of butene and water, significantly improving the efficiency of the one-time conversion to sec-butanol and greatly saving the large amount of energy required for material recycling.

The invention relates to a walnut-based fragrance-carrying granular material with slow release performance and a preparation method and application thereof, and the preparation method comprises the following steps: (1) carrying out microwave treatment on a walnut shell crushed material to obtain a modified walnut shell crushed material; (2) mixing the crushed walnut shells with liquid essence, and carrying out adsorption treatment to obtain fragrant walnut shell particles; and (3) carrying out film coating treatment on the fragrance-carrying walnut shell particles by using a film forming solution, and then drying and screening to obtain the walnut-based fragrance-carrying particle material with the slow-release performance. According to the invention, by virtue of a three-step synergistic technology of microwave modification, adsorption fragrance carrying and film coating, high adsorption, high stability and slow release performance which are difficult to achieve by a common natural fragrance carrying material are realized, and the composite material is suitable for multiple fields of foods, tobaccos, daily chemicals and the like.

This utility model relates to the field of tables and benches, and in particular to a tea-brewing table and bench, comprising a table body including a tabletop and a first support frame located below the tabletop. A hole is provided at the center of the tabletop. The first support frame is a ring-shaped support frame with a vertical projected area smaller than the projected area of ​​the tabletop. A functional compartment, installed in the hole, is either a storage basket or a stove body. The stove body includes the functional compartment and an induction cooker or charcoal stove that can rotate 180° around a horizontal axis, installed inside the functional compartment. Through the synergistic effect of the hourglass-shaped structure of the ring support frame (a combination of first rings with diameters increasing and decreasing from bottom to top) and the rotating stove body mechanism (a functional compartment with a limiting groove and a T-shaped block mounting bracket), structural stability is ensured while providing legroom that conforms to the user's sitting posture curve. The largest diameter ring is precisely positioned within the ankle height range.
