In hydrolysis of lignocellulosic materials, a lot of compounds which are inhibitory to microorganisms can be formed such as: weak acids, furan derivatives, and phenolic compounds.
Methods Chalcone derivatives were synthesized from benzaldehyde derivatives and acetophenone by using weak alkali potassium carbonate as based catalyst in water via phase - transfer catalysis.
方法以苯甲醛衍生物和苯乙酮为原料，弱碱碳酸钾为催化剂，水为溶剂，用相转移催化法合成查耳酮衍生物。

Finally, under suitable assumptions, we obtain the upper semicontinuity and the lower semicontinuity of second-order adjacent derivatives for the weak perturbation maps.
