The cloud point extraction behavior of aluminum(III) with 8-quinolinol (HQ) or 2-methyl-8-quinolinol (HMQ) and Triton X-100 was investigated in the absence and presence of 3,5-dichlorophenol (Hdcp). Aluminum(III) was almost extracted with HQ and 4(v/v)% Triton X-100 above pH 5.0, but was not extracted with HMQ-Triton X-100. However, in the presence of Hdcp, it was almost quantitatively extracte...

The goal of present study was to investigate kinetics of supercritical carbon dioxide (SC CO2) extraction of essential oils from dried clove buds and oregano leaves. Total extract yields after exhaustion of plant material at 10 MPa and 40°C (after consumption of 94.3 kgCO2/kg plant material) were 18.2% and 1.0 %, respectively. Synergistic effect in the extraction process was also investigated u...
