Description

Technical Field

[0001] This utility model relates to the field of monobutyltin trichloride distillation technology, and in particular to a monobutyltin trichloride distillation purification device. Background Technology

[0002] Monobutyltin trichloride is a chemical substance with the molecular formula C4H9Cl3Sn. It is a colorless, clear, transparent liquid or a light yellow transparent liquid. It can be used as a glass coating agent and glass reinforcing agent, known as hot-end coating fluid (MBTC). A 99% purity version can be used for LOW-E glass coating, TCO photovoltaic glass coating, and energy-saving conductivity. Monobutyltin trichloride has anti-corrosion, bactericidal, and antifungal properties, and is used as a rodenticide, rodent-repellent cable coating, and synthetic intermediate. It is widely used in wood preservation, marine paints, and as a pharmaceutical intermediate in the pharmaceutical industry. It can also be used as a catalyst, to introduce dibutyltin groups in organic synthesis, and in prostaglandin synthesis. Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a mixed liquid or liquid-solid system. It involves evaporating the lower-boiling-point component and then condensing it to separate the entire component. It is a unit operation combining evaporation and condensation. Compared to other separation methods such as extraction, filtration, and crystallization, its advantage is that it does not require the use of solvents other than those used in the system components, thus ensuring that no new impurities are introduced.

By setting a buoyancy plate, the bottom of the sliding rod is kept on the upper layer of the solution inside the heating chamber. By setting a heat-conducting component, the heat generated by the electric heating wire is concentrated at the top of the sliding rod.

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a distillation and purification apparatus for monobutyltin trichloride according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the monobutyltin trichloride distillation purification equipment provided by this utility model includes a heating box 1 and a condensing box 2, wherein a heating mechanism is provided inside the heating box 1;

[0027] The heating mechanism includes a baffle 8, a mounting cylinder 9, a sliding rod 10, a buoyancy plate 11, and an electric heating wire 16. The baffle 8 is fixedly installed inside the heating box 1, the mounting cylinder 9 is fixedly installed on the top of the baffle 8, the sliding rod 10 is slidably connected inside the mounting cylinder 9, the bottom of the sliding rod 10 is located at the bottom end of the baffle 8, the buoyancy plate 11 is fixedly installed on the top of the sliding rod 10, the electric heating wire 16 is fixedly installed inside the sliding rod 10, and a heat-conducting component 17 is fixedly installed on one side of the top of the sliding rod 10.

[0028] It should be noted that the sliding direction of the sliding rod 10 can be restricted by setting the mounting cylinder 9, the bottom of the sliding rod 10 will be kept on the upper layer of the solution inside the heating box 1 by setting the buoyancy plate 11, and the heat-conducting component 17 will concentrate the heat generated by the electric heating wire 16 to the top of the sliding rod 10. Since monobutyltin trichloride has a higher density than water, the heat can be concentrated to heat the water in the monobutyltin trichloride solution, and the water in the monobutyltin trichloride solution will evaporate quickly, thereby making the purification efficiency higher and the resource waste less.

[0029] In some embodiments, such as Figure 3 As shown, the sliding rod 10 has an installation cavity 15 inside, the electric heating wire 16 is fixedly installed inside the installation cavity 15, the top of the sliding rod 10 is fixedly installed with a heat-conducting component 17 near one side, one end of the heat-conducting component 17 is in contact with the electric heating wire 16, and the top of the buoyancy plate 11 is fixedly installed with a float ball 14.

[0030] It should be noted that by setting a heat-conducting element 17 at the top of the sliding rod 10, the heat generated by the electric heating wire 16 will be concentrated at the top of the sliding rod 10. By setting a float ball 14, the buoyancy of the sliding rod 10 can be increased, so that the top of the sliding rod 10 is always at the top of the solution.

[0031] In some embodiments, such as Figure 2 As shown, a connecting pipe 5 is fixedly installed on the top of the heating box 1. One end of the connecting pipe 5 is located inside the condensing box 2 near the bottom. A feeding port 3 is fixedly installed on the top of the heating box 1. A drain pipe 4 is fixedly installed on the side wall of the heating box 1. The drain pipe 4 is located on the top of the baffle 8. A drain pipe 7 is fixedly installed on one side of the condensing box 2.

[0032] It should be noted that the feeding port 3 can be used to add monobutyltin trichloride solution into the heating box 1. Solenoid valves are installed in the drain pipe 4 and the drain tube 7. The drain pipe 4 can be used to discharge the treated solution in the heating box 1, and the drain tube 7 can be used to discharge the condensate in the condensation box 2.

[0033] Example 2

[0034] In some embodiments, such as Figure 4 As shown, a mounting bracket 13 is fixedly installed inside the condenser box 2. A filter screen 12 is fixedly installed on the top of the mounting bracket 13. An exhaust pipe 6 is fixedly installed on the top of the condenser box 2. A connecting groove 18 is opened inside the mounting bracket 13. The end face of the connecting groove 18 is trapezoidal. A protrusion 19 is fixedly installed on the top of the mounting bracket 13. A contact element 20 is fixedly installed on the inner wall of the connecting groove 18.

[0035] It should be noted that by setting the contact element 20 inside the connecting channel 18, the contact area between the connecting channel 18 and the steam can be increased, so that most of the steam will adhere to the connecting channel 18 when it passes through the connecting channel 18, thereby making the steam condense into water more quickly. The air passing through can be filtered by setting the filter screen 12.

[0036] Working principle: During use, the monobutyltin trichloride solution to be purified is added into the heating box 1. The bottom of the sliding rod 10 is kept on the upper layer of the solution inside the heating box 1 by setting the buoyancy plate 11. The heat generated by the electric heating wire 16 is concentrated at the top of the sliding rod 10 by setting the heat conduction component 17. Since the density of monobutyltin trichloride is greater than that of water, the heat can be concentrated to heat the water in the monobutyltin trichloride solution. The water in the monobutyltin trichloride solution evaporates quickly. The evaporated water vapor enters the bottom of the condensing box 2 through the connecting pipe 5 and moves from bottom to top. The contact component 20 is set inside the connecting groove 18 to increase the contact area between the connecting groove 18 and the steam. When the steam enters the connecting groove 18, most of it will adhere to the connecting groove 18, so that the steam will condense into water more quickly. Then, the treated solution in the heating box 1 can be discharged through the drain pipe 4, and the condensate in the condensing box 2 can be discharged through the drain pipe 7.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
