Reaction Steps
A crude levulinic acid composition comprising 14.9 g (0.128 mol) levulinic acid, 0.449 g (9.76×10−3 mol) formic acid, 30 g (1.66 mol) DI water, and 0.3484 g (1.50×10−3 mol) camphor sulfonic acid was esterified with 2.89 g (3.21×10−2 mol) 1,4-butanediol. The procedure for Example 6 was followed, and analysis of the reaction mixture by GC-FID showed a peak corresponding to LA-BDO-LA.
