Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary devices for alkyd resin synthesis experiments of organic chemical products, in particular to an anti-splashing device for alkyd resin synthesis experiments. Background Art
[0002] The raw materials for the synthesis reaction of alkyd resin include soybean oil, glycerol, benzoic acid and diluent solvent. During the synthesis experiment, these materials are added together into a four-necked bottle and heated to react, and the alkyd resin is synthesized by esterification reaction at high temperature. Since water is produced during the synthesis of alkyd resin, in order to allow the synthesis experiment to proceed smoothly, part of the water needs to be removed through a condenser and a water separator. During the water separation process, a small amount of water will flow back into the four-necked bottle, causing boiling and generating a large number of bubbles. Since the space of the four-necked bottle is small, the sudden increase in air pressure will cause the reaction raw materials to be ejected from the condensation pipe mouth, causing the loss of raw materials. The ejection of high-temperature raw materials is likely to cause personal injury, which not only affects the progress of the synthesis experiment, but also may cause safety accidents. Utility Model Content

DETAILED DESCRIPTION
[0013] The specific implementation of the anti-splash device of the utility model is further described in detail below through the accompanying drawings.
[0014] Figure 1-Figure 2 As shown, the anti-splash device for alkyd resin synthesis experiment of the utility model comprises a main body 1, a reflux duct 2, an inner tube 3, a condenser 7 and a three-way valve 8; the main body 1 is a circular tube with upper and lower cover plates, a vent 4 is provided in the middle of the upper cover plate, and a connection port 6 is provided in the middle of the lower cover plate for connecting the inner tube 3; the condenser 7 is provided with a condenser water outlet 7-1, a condenser water inlet 7-2, an upper condenser connection port 7-3 and a lower condenser connection port 7-4; the upper part of the inner tube 3 is provided with a plurality of evenly distributed spray ports 5, and the lower part is provided with a rubber sleeve 6-1 for connecting the upper condenser connection port 7-3; the upper end of the reflux duct 2 is connected to the bottom side of the main body 1, and the lower end is connected to the horizontal interface of the three-way valve 8 after connecting the check valve 8-1; the upper interface of the three-way valve 8 is connected to the lower connection port 7-4 of the condenser, and the lower interface of the three-way valve 8 is connected to the water distributor 9.
[0015] The operation steps of the anti-splash device of the utility model alkyd resin synthesis experiment are as follows:
[0016] Before starting the alkyd resin synthesis experiment, make sure that the device is connected properly, that is, make sure that the connection port 6 is aligned with the connection port 7-3 on the condenser, and at the same time make sure that the rubber sleeve 6-1 is firmly covered on the connection port 7-3 on the condenser, and close the check valve 8-1.
[0017] After the experiment starts, the material is heated up. When the temperature reaches 200°C, the material begins to react to generate small molecule alkyd resin and water. As the temperature continues to rise, the water will be evaporated from the water separator 9 with the steam. At this time, the heating rate should not be too fast, and the temperature continues to rise with a small reflux. When the temperature reaches 260-270°C, the degree of reaction intensifies. At this time, if the water in the water separator 9 or the rubber plug of the stirring paddle returns to the four-necked bottle 13, the material is easy to boil and rush the material, and then the material is connected to the condenser through the water separator 9 and rushes out into the inner tube 3 and overflows from the spray port 5. The sprayed liquid enters the main body 1 and is collected; open the check valve 8-1 and the liquid returns to the four-necked bottle 13 through the reflux conduit 2, and circulates continuously until the experimental reaction is completed.
