In this paper,the progress on diphenolic acid preparation by condensation reaction of levulinic acid and phenol is introduced. 利用乙酰丙酸和苯酚缩合反应制取双酚酸。
The work proved the possibility of substituting inorganic acid with strong acidic resins for levulinic acid preparation from biomass. 该研究结果证实了用耐水型强酸性树脂替代现有的无机酸催化制备乙酰丙酸的可能性。
