Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rosin derivative preparation, and particularly relates to a preparation method of hydrogenated rosin derivative. BACKGROUND

[0002] Rosin is a natural resin with significant thermoplastic properties. The chemical composition of rosin is mainly composed of resin acids, in addition to some fatty acids and neutral substances. These components work together to make rosin and its various derivatives have very wide applications in industrial and commercial fields.

[0003] Due to the presence of unsaturated conjugated double bonds in the molecular structure of rosin, they have high sensitivity to oxygen. When rosin is exposed to an environment containing oxygen, it is very easy to undergo oxidation reaction. This oxidation will cause the performance of rosin materials to gradually decline, affecting its use value. Therefore, in order to improve the practicality and stability of rosin, researchers and engineers have developed various modification technologies, including isomerization, disproportionation, hydrogenation, maleation and esterification methods. After processing by these methods, the derivatives of rosin not only maintain the original properties, but also increase new functions, thereby showing more excellent performance in different application occasions. Among its derivative products, hydrogenated rosin is an important modified material, which can be prepared by hydrogenation reaction. Hydrogenated rosin has good antioxidant properties, low brittleness and high thermal stability, and is non-toxic, so it has a very wide range of applications in industry, such as adhesives, synthetic rubber, paint, ink and the like.

[0004] The catalysts with noble metal as active component have made good progress in the hydrogenation of rosin, but the noble metal also has some inevitable shortcomings, such as high price, relatively limited availability and instability, which greatly increases the cost of its application in industrial production. In order to improve this problem, researchers begin to focus on the development of non-noble metal catalysts, and nickel-based catalysts are the most widely used among them, which can provide reliable guarantee for the catalytic cracking hydrogenation of rosin. For the purpose of protecting the ecological environment, people pay more and more attention to the development of green chemistry and environmentally friendly chemistry. Because the residual solvents after various chemical reactions can cause more or less harm to the ecological environment and human health, it is particularly important to follow the requirements of green chemistry, such as the reuse of catalysts and the use of green solvents. The solvent can play a certain auxiliary role in the interaction between the carrier and the metal and in the adsorption and desorption steps, so it can affect the selectivity and activity of the reaction, which can be attributed to the geometry and polarity of the solvent. Researchers have tried to use ethanol, n-octane and other organic solvents as reaction solvents for catalytic hydrogenation. Although these organic solvents are widely used in chemical production, they can escape into the environment and cause various air pollutants. Water has the advantages of abundance and low cost, and it is easy to obtain and separate from the reaction mixture. In many cases, water as a solvent can not only accelerate the rate of organic reaction to some extent, but also improve the regional selectivity of chemical reaction. Due to the hydrophobicity of rosin hydrogenation catalyst, it has poor solubility or miscibility with water, which leads to low yield. Therefore, how to improve the miscibility of rosin hydrogenation catalyst in water has become an important research direction. SUMMARY

[0005] The purpose of the present application is to provide a preparation method of hydrogenated rosin derivatives, which solves the problem of low reaction yield caused by poor miscibility and dispersibility of rosin hydrogenation catalyst in water in the prior art.
