Description

Technical Field

[0001] This utility model relates to the field of phase separation technology, specifically to a condensation phase separation system for esterification products. Background Technology

[0002] Esterification is a chemical reaction in which an ester bond forms between an acid and an alcohol. In esterification, the carboxyl group (-COOH) in the acid molecule reacts with the hydroxyl group (-OH) in the alcohol molecule to produce an ester molecule and a water molecule. Esterification can be acid-catalyzed or enzyme-catalyzed. It is commonly used in organic synthesis to produce various ester compounds. Esterification has wide applications, such as in the food industry for synthesizing food flavorings, in the pharmaceutical industry for synthesizing drugs, and in the cosmetics industry for synthesizing perfumes. Furthermore, esterification can be used to prepare ester solvents because esters have low boiling points and good solubility, making them suitable for many solvent applications.

[0003] After condensation, the esterification product will separate into two different liquids. However, a drain is usually set at the bottom of the container to drain the bottom layer first, and then drain the top layer liquid through the drain. Since the bottom layer liquid is attached to the drain and the inner wall of the pipe, it will contaminate the top layer liquid, resulting in the top layer liquid being mixed with more bottom layer liquid. Utility Model Content

[0004] In view of the problems existing in a current condensation phase separation system for esterification products, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a condensation and phase separation system for esterification products, which solves the problem that the esterification products will separate into two different liquids after condensation. However, usually a drain port is set at the bottom of the container to drain the bottom layer of the container first, and then the upper layer of liquid is drained through the drain port. Since the bottom layer of liquid is attached to the drain port and the inner wall of the pipe, it will contaminate the upper layer of liquid, resulting in the upper layer of liquid being mixed with a lot of the bottom layer of liquid.

The secondary cold hydrazine is connected to the vacuum pump group. A two-stage distillation reflux structure is provided between the component tank and the evaporator. The first-flavor A tank has a first upper liquid outlet and a first lower liquid outlet at the bottom. The top-grade incense B can has a second upper liquid outlet, and the bottom of the top-grade incense B can has a second lower liquid outlet.

The sixth interface and the fourth interface are respectively used to connect to the first-stage cold hydrazine and the second-stage cold hydrazine, and the second interface and the fifth interface are used to connect to the heavy component tank and the light component tank.

[0008] As a preferred embodiment of the esterification product condensation and phase separation system of this utility model, the top of the evaporator is provided with a first interface for feeding, the first interface is connected to a feed tank through a conduit, and a condenser tube is provided inside the evaporator.

[0019] The top of the evaporator 4 is provided with a first port 41 for feeding. The first port 41 is connected to a feed tank through a conduit. A condenser tube is installed inside the evaporator 4.

[0020] The secondary distillation reflux structure includes a second suction pump 13 connected to the outlet of the heavy component tank 2 via a conduit, and the output end of the second suction pump 13 is connected to the evaporator 4 via a second reflux pipe 14.
