Description

Technical Field

[0001] The utility model relates to the technical field of dihydroacetate production, and more specifically to a purification device in the process of preparing dihydroacetate. Background Art

[0002] Dihydropinyl acetate has a fresh pine-like and citrus-like aroma with a slight grassy scent. It is widely used in lavender, citrus and fougere flavors in household detergents and colognes. It is an excellent blending agent for synthetic fragrances such as isoborneol acetate, dihydromyrcenol, linalyl acetate and pine-type, fruity and citrus-type fragrances. The main preparation process of dihydropinyl acetate is to esterify dihydropinyl alcohol, a product of pine alcohol hydrogenation, with acetic anhydride under acid catalysis to obtain dihydropinyl acetate. The main raw material for the preparation of dihydropinyl acetate is turpentine oil, which is a liquid extracted from the resin of coniferous plants by distillation or other methods.

[0003] After searching, the utility model patent with announcement number CN217340980U discloses a purification equipment in the process of preparing dihydroacetic acid pine ester, including: a stirring barrel, a feed port connected to the interior of the stirring barrel is fixedly installed on the top, a stirring assembly, which is rotatably arranged inside the stirring barrel, a storage barrel, a feed pipe is connected between the storage barrel and the stirring barrel, and a discharge pipe is also connected to the bottom of the storage barrel, and an insulation device, the material is poured into the stirring barrel through the feed port, and the first rotating shaft and the driving gear sleeved on the outer wall thereof are driven to rotate by the rotation of the output end of the motor, and the driving gear drives multiple driven gears meshing on the outside to rotate synchronously, driving the second rotating shaft to rotate, and the first rotating shaft and the multiple stirring rods on the outer wall of the second rotating shaft realize stirring of the material in the stirring barrel during the rotation process, and when the heating rod is energized, it will transfer heat to the material in the stirring barrel to realize stirring at high temperature. However, the above patents still have the following shortcomings: when the turpentine material is temporarily stored in a storage barrel, the storage barrel itself cannot keep the turpentine well warm, and it is not convenient to control the temperature of the turpentine in the mixing barrel and the storage barrel; in addition, the effect of stirring the turpentine only by the stirring rod is not good, and the heating range of the turpentine by the heating rod in the second rotating shaft is limited, which affects the heating efficiency. For this reason, we propose a purification device in the process of preparing dihydroacetic acid pine ester. Utility Model Content
