Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, in particular to a synthesis device for 1-ethynyl-1-cyclohexanol. Background Art

[0002] As an organic compound, ethynyl-1-cyclohexanol may be used in many fields. As a starting material or intermediate in organic synthesis, it can be used to synthesize other organic compounds, such as drugs, fragrances, dyes, etc., and used to prepare polymers, coatings, adhesives and other materials. It has specific properties and applications. In the preparation process of 1-ethynyl-1-cyclohexanol, a reactor is required to react acetylene with liquid ammonia. The reactor should have corrosion resistance and be able to withstand high pressure.

[0003] However, in the prior art, in the 1-ethynyl-1-cyclohexanol reactor, during the processing, dry acetylene needs to be introduced into liquid ammonia, and sodium is added at the same time for reaction, and mixing is performed during the reaction. During the mixing process, cyclohexanone is then added dropwise, but the reaction temperature of acetylene and liquid ammonia needs to be kept at a low temperature. However, when cyclohexanone at room temperature is dropped into the reactor, the temperature difference is large, which easily reduces the reaction speed and affects the processing efficiency. To this end, we provide a 1-ethynyl-1-cyclohexanol synthesis device to solve the above problems. Utility Model Content
