Abstract

The invention discloses a method for preparing a high-purity cardanol. The method comprises a process of extracting a cardanol from a natural cashew nut shell liquid with a molecular still, wherein the molecular still consists of a cylindrical shell, a rotor and a built-in condenser, the lower part of the cylindrical shell is provided with a heater, a fixed frame is provided with a film blade and an antispray device; the natural cashew nut shell liquid is poured into the cylindrical shell from the top and the rotor is rotated between the cylindrical shell and the condenser at the same time to distribute the natural cashew nut shell liquid on a heating surface of the cylindrical shell continuously and evenly; and the film blade is used to spread the feed liquid to a layer of turbostratic liquid film and the film blade is used to spirally push the turbostratic liquid film to the built-in condenser to cool the turbostratic liquid film into a liquid; finally the liquid flows down along a pipe of the condenser and is discharged from a discharge pipe to obtain the high-purity cardanol. The method can improve the yield and purity of the cardanol.

Description

Technical field: [0001] The invention relates to the field of chemistry, in particular to a method for preparing organic polymer compounds, in particular to a method for preparing high-purity cardanol Background technique: [0002] One of the greatest utilization values ​​of petroleum is fine chemical polymer materials, and one of the highest values ​​of biomaterial energy is the effective replacement of fine chemical polymer materials. Studies have shown that cardanol is the most promising non-grain oil substitute among similar biomass chemical materials. Special functional polymer chemical materials can be synthesized with cardanol, which can solve problems that cannot be solved by petroleum phenolic compounds. However, due to technical reasons, the refining and extraction of cardanol has become a major problem, the industrial production of high-purity cardanol cannot be realized, and the utilization value of cardanol is greatly limited. At present, the high-temperature r...
