Description
Summary:In this paper, ionic liquid method and ultrasound-assisted ionic liquid method were used to extract lignin and the effects of various factors on the extraction of lignin were investigated. The properties and antioxidant properties of lignin were studied. The lignin extraction rates of the two methods were 93.60% and 94.01%, respectively. On this basis, the oxidation resistance and stability of lignin in polypropylene were studied, and the added value of lignin was increased. It was shown that the lignin extracted by two different methods had a certain antioxidant effect, and the ultrasonic assisted ionic liquid lignin had the best antioxidant effect.
