A low-cost isoniazid-based scavenger resin was previously prepared and successfully used to capture aldehydes and ketones in solution by using a batch approach. The present work compares batch and continuous processes in relation to the preparation of the scavenger resin and the effectiveness of cyclohexanone scavenging. The batch preparation of the resin proved to be the better choice because the resin produced in the continuous flow suffered deformation on its surface that prevented access to the active sites in the internal porous polymer matrix. Conversely, the continuous-flow approach presented higher capturing yields than the batch. The optimized scavenging process was successfully used to remove formaldehyde present in a solution and the carbonyl compounds present in an ethanolic extract of Cymbopogon citratus.

使用清除剂树脂捕获醛和酮的连续过程和间歇过程的比较

先前已经制备了低成本的异烟肼基清除剂树脂,并通过使用分批方法成功地用于捕获溶液中的醛和酮。本工作比较了与清除剂树脂的制备和环己酮清除效果有关的分批和连续过程。分批制备树脂被证明是更好的选择,因为在连续流动中产生的树脂在其表面上发生变形,从而阻止了其进入内部多孔聚合物基质中的活性位点。相反,连续流方法比批次具有更高的捕获率。优化的清除过程已成功用于去除溶液中存在的甲醛和柠檬柠檬柏的乙醇提取物中存在的羰基化合物
