Abstract

Laevulinic acid is prepared by heating at 130-210 DEG C., under pressure, a solution of sucrose not exceeding 25 per cent concentration with hydrobromic acid, or with hydrochloric acid admixed with sodium bromide. In the examples, sucrose which is employed as evaporated crude cane sugar juice in one example, or other hexose yielding carbohydrate (such as dextrose) is heated under pressure with hydrochloric acid and sodium bromide. The humin material is filered off and the solution extracted with a volatile ether. The solvent is evaporated from the extract and formic acid removed by distilling under reduced pressure.
