57.2 g 1,4-butanediol (0.636 mole), 254.2 g montanic acid and 0.4 g tin powder were heated to 210° C. as in Example 1 with application of a gentle vacuum. The vacuum was increased to 152 mbar over a period of 3 hours. The mixture had an acid value of 1.5. A brownish-yellow wax having a dropping point of 77° C. was obtained after cooling to 100° C., bleaching and filtering.
