Embodiment 1

[0034] Add 10.38 g of β-caryophyllene, 4.90 g of maleic anhydride, 0.584 g of di-tert-butyl peroxide and 30.6 g of cyclohexanone into a 100 ml three-necked flask equipped with a thermometer and a magnetic stirring bar. Under the protection of nitrogen, raise the temperature to 150°C, react for 1 hour, then stop the reaction, pour the reactant into a large amount of methanol, a white precipitate is precipitated, and then perform suction filtration to obtain a white powdery solid. After drying, the measured mass is 11.1g , yield 72.63%. The molecular weight of the copolymer measured by GPC M n for 1404, M w for 3249. Then get 2g copolymer and join in the one-necked flask that the NaOH solution of 5% mass fraction is housed, heat and reflux to transparent, then pour the reactant into a large amount of methanol to separate out a white precipitate, suction filter, and dry to obtain a saponified product. The surface tension of the object was measured, and the results are shown in...

Embodiment 2

[0036] 10.38 g of β-caryophyllene, 4.90 g of maleic anhydride, 0.438 g of di-tert-butyl peroxide and 22.93 g of cyclohexanone were added. Under the protection of nitrogen, the temperature was raised to 145° C., and the reaction was carried out for 1 hour. The other conditions were the same as in Example 1. The quality of the finally obtained copolymer was 11.1 g, and the yield was 79.83%.

Embodiment 3

[0038] 10.38 g of β-caryophyllene, 4.90 g of maleic anhydride, 0.584 g of di-tert-butyl peroxide and 30.57 g of cyclohexanone were added. Under the protection of nitrogen, the temperature was raised to 150° C., and the reaction was carried out for 10 minutes. The other conditions were the same as in Example 1. The quality of the finally obtained copolymer was 9.6 g, and the yield was 62.81%.

Abstract

The invention provides a beta-caryophyllene-maleic anhydride copolymer as well as a preparation method and an application thereof. The copolymer contains acid anhydride bonds and is prepared from beta-caryophyllene and maleic anhydride through copolymerization. Beta-caryophyllene and maleic anhydride in the ratio being 4:1-1:6 are dissolved in a solvent or directly subjected to bulk mixing under protection of nitrogen, a radical initiator is added, and then the beta-caryophyllene-maleic anhydride copolymer is obtained through a reaction under a heating condition. The beta-caryophyllene-maleic anhydride copolymer can be widely applied to industries such as paint, cosmetics, food and the like. An anionic surfactant is obtained through saponification of the beta-caryophyllene-maleic anhydride copolymer. The reaction conditions are mild, the process is simple, and industrial production is easy.

Description

technical field [0001] The invention relates to polymer preparation, in particular to a β-caryophyllene-maleic anhydride copolymer and its preparation method and application. technical background [0002] my country's masson pine resin output is large, ranking first in the world. Masson pine resin is distilled to obtain light turpentine, heavy turpentine and rosin. At present, there are many studies on light turpentine and rosin, and there are many industrialized products, but the research on heavy turpentine is still relatively scarce, and there are not many industrialized products, resulting in the price of heavy turpentine has been in a downturn. The main components of heavy turpentine are longifolene and β-caryophyllene. Among them, the content of β-caryophyllene can reach about 19%. The research and utilization of β-caryophyllene is of great significance for improving the refined utilization rate of heavy turpentine. [0003] β-Caryophyllene belongs to bicyclic sesqu...
