Optimization of the extraction process of Pinus sylvestris L. pine bark with monoethanolamine

Abstract

The paper presents the results of optimizing the process of extraction of the bark of Pinus sylvestris L. Scotch pine. The input parameters were the duration of the process and the concentration of the monoethanolamine solution. The experimental data were processed using the STATGRAPHICS® Centurion software package. It has been established that the maximum extraction of extractive substances occurs when the duration of the extraction process is 5 hours with a concentration of monoethanolamine of 5%.
