LIEBERMANN [1885] showed that boiing benzene extracted an alcohol-insoluble wax which he called coccerin from the cochineal insect (Coccu8 cacti). By saponification with strong alcoholic potash and separation of the acids as calcium soaps he obtained an alcohol, cocceryl alcohol, which melted at 101-104, and an acid, coccerinic acid, which melted at 92-93o. Two years later Liebermann and Bergami [1887] investigated the structure of these two compounds. Analysis of cocceryl alcohol suggested that it was a C30-alcohol with two oxygen atoms.
