Application 9001

Immobilized catalyst recycling using a SpinChem® rotating bed reactor (RBR) and a Mettler-Toledo EasyMax™ 102 Advanced synthesis workstation. The process proved very time efficient as no filtration steps were needed between cycles, or for the samples extracted for analysis during each run. Washing of the resin between runs was fast, simple and robust, without running the risk of material loss.

    Details

    Conditions: A SpinChem® S2 RBR containing Novozyme 435 (1 g), was rotated at 500 rpm in a preheated (30 °C) substrate solution containing 2-Ethyl-1-hexanol (5.21 g), Vinyl acetate (3.44 mL) and heptane (110 mL). The reaction was repeated for seven cycles, and samples for each run were taken after 0, 10, 20, 30 and 60 min. Analysis of 2-Ethylhexyl acetate product was done suing GC-FID after 1:9 dilution in heptane containing internal standard (tetradecane, 50 mmol). Between cycles, the resin was washed by spinning the RBR in heptane for 1 min.

Application 1019

Poster on study of catalyst recycling during esterification and transesterification reactions with immobilized lipases in rotating bed reactors. Data from several laboratories showed that no attrition or grinding occurred and that no filtration was necessary between reaction cycles. The production capacity was estimated to 50 kilograms per gram of catalyst thanks to the high catalyst stability.
