41.1 g sorbitol (0.226 mole), 271.1 g montanic acid (0.678 mole) and 0.4 g tin powder were heated to 200° C. as in Example 1 with application of a gentle vacuum. The vacuum was increased to 15 mbar over a period of 14 h, by which time the acid value had fallen to 5. After cooling to 100° C., the product was filtered, giving a brown hard wax having a dropping point of 78° C.
