Siberian cedar bark processing with mathematical optimization of tannin and ethanol-lignin extraction
A method for the Siberian cedar bark integrated processing with mathematical optimization for tannins and ethanol-lignins obtaining was proposed. The effect of the extraction time and the concentration of ethanol on the yield of tannins and the effect of the temperature and processing time on the yield of ethanol-lignin from the bark of Siberian cedar have been established. By the method of experimental optimization, it was found that high concentration of ethanol used in the extraction process, the release of tannins sharply decreases over time, and when more dilute solutions are used, the extraction is intensified. By the method of mathematical optimization, it is shown that the maximum yield of tannins up to 15.5% is achieved at a concentration of an aqueous solution of ethyl alcohol of 70.1% and an extraction duration of 11.2 hours. It has been established that the optimal conditions for obtaining ethanol-lignin of cedar bark with a yield of 19.4% are the concentration of ethyl alcohol 61.1% and the process temperature 232.2 C. The isolated tannins and ethanol-lignins of the cedar bark were characterized by FTIR spectroscopy.
