The present invention provides a method of making carboxylic acids from levulinic acid, such as succinic acid and 3-hydroxypropanoic acid, by reacting levulinic acid with an oxidant such as hydrogen peroxide under acidic or basic conditions.

3‐Hydroxypropanoic acid (HPA), a precursor to acrylic acid, can be produced in high yield by oxidation of the biomass‐derived platform chemical levulinicacid. While treatment of levulinicacid with H2O2 under acidic conditions gives predominantly succinic acid, a remarkable reversal of selectivity is observed under basic conditions, leading either directly to HPA or, under modified conditions, initially
3-羟基丙酸(HPA)是丙烯酸的前体,可通过氧化生物质衍生的平台化学乙酰丙酸来高产。虽然在酸性条件下用H 2 O 2处理乙酰丙酸主要为琥珀酸,但在碱性条件下观察到了显着的选择性逆转,直接导致了HPA或在修饰条件下最初导致了3-(氢过氧)丙酸,可以定量氢化为HPA。
