Penicillium camemberti lipase immobilized on a magnetized poly(styrene‐co‐divinylbenzene) was used as a biocatalyst for isopropyl palmitate synthesis. The reaction conditions were determined by 22 factorial central composite design. A mathematical model based on a simplified kinetic approach was developed to describe the system and validated with the experimental data. An assay carried out in a stirred‐tank reactor confirmed the proposed model. The ester was purified and the properties such as density and water content were similar to those found in commercially available isopropyl palmitate.

固定化在磁化聚合物基质上的脂肪酶合成棕榈酸异丙酯

固定在磁化的聚(苯乙烯-co-二乙烯基苯)上的卡门培尔青霉脂肪酶被用作棕榈酸异丙酯合成的生物催化剂。反应条件由2 2阶乘中心复合设计确定。建立了基于简化动力学方法的数学模型来描述系统,并用实验数据进行了验证。在搅拌釜反应器中进行的测定证实了所提出的模型。将该酯纯化,并且诸如密度和水含量的性质类似于可商购的棕榈酸异丙酯中发现的那些。
