▎ 摘  要

NOVELTY - Purifying cashmeran raw material indane, comprises (1) adding galaxolide indane to alkali solution, heating and stirring to wash, allowing to stand and layering, separating lower layer of alkali water, adding pure water, stirring and washing, allowing to stand and layering, and separating the lower layer of water to obtain crude cashmeran indane; (2) adding aluminum-magnesium modified hydroxymethylcellulose coagulant to the crude product indane obtained in step (1), fully stirring, allowing to stand and carrying enhanced coagulation treatment to obtain the supernatant; (3) adding redox-treated graphene powder to the supernatant obtained in step (2), fully stirring, carrying adsorption treatment and allowing to stand to obtain the supernatant; and (4) adding the supernatant after adsorption treatment obtained in step (3) into the indane rectification tower, and obtain the high-quality indane for making cashmeran by rectification. USE - The method is useful for purifying cashmeran raw material indane. ADVANTAGE - The method: can purifies the pentamethylindane in basic flavor galaxolide to synthesize the high-grade flavor cashmeran to increase the economic benefits of the enterprise.
