Abstract

Black condensates (BC) are wastes of the insulation corkboard industry that contain several valuable chemicals, including friedelin, a terpene exhibiting biological activity. Herein, we report a straightforward procedure to extract friedelin from BC. Using this procedure, we were able to extract friedelin with yields between 0.4% and 2.9% and to further purify it obtaining purities from 77.0% to 99.3% (HPLC). The initial BC (2 batches), extracted raw product and purified friedelin were analyzed using FTIR. The extraction yields and purities were found to be directly related to the intensity of the carbonyl vibration at 1713 cm-1 in the FTIR spectrum of the used BC batch. Therefore, these spectra can be used to screen and select BC batches suitable for friedelin extraction.
