Description
  • Two transesterification processes of potential large scale application have been studied. Continuous glycerolysis of soybean oil with the aim to produce a mixture of the glycerides to be used in the manufacture of alkydes and transesterification of the oil with trimethylolpropane, being of interest in view of the only so far reported synthesis based on the use of the methyl esters. A heated packed bed reactor filled with the commercial enzyme catalyst Novozym 435 and connected to a preheated magnetically stirred reservoir was used for this purpose. The reaction mixture was pumped upwards through the column. Optimum conditions were found by varying several process parameters and the product composition compared to that obtained in a stirred reactor. The steady catalyst operation has been confirmed in 100 hour experiment. The product showed good stability at room temperature for 150 days.
