Emission of Volatile Organic Compounds from the Heat Treatment of Afrormosia and Newtonia Wood: Effects of Air and Palm Oil Heat Media

The objective of this work was to study the influence palm oil on VOCs emitted during heat treatment Afromosia (Pericopsis Elata Van Meeuwen) and Newtonia (Newtonia paucijuga Harms) wood by comparing under air. Two batches Afrormosia samples were heated air at temperatures 160 °C, 180 200 °C for 2 h. Then, collected Solid Phase Micro Extraction (SPME) measured using a Gas Chromatograph Mass Spectrometer (GC-MS). results showed that temperature, species, medium have great categories percentages emitted. In treatment, ethers most from when these woods thermally treated °C. more esters, while continued emit same conditions. Moreover, ketones aldehydes, respectively. Regarding oil, similarity with those conditions observed. Furthermore, main factor conditioning nature treatment. general, Afrormoshia emitted, such as alcohols, alkanes, ethers, decreased temperature. Ethers increased processing At percentage aldehydes highest, while, esters highest. Similarly, adehydes, alcohols abundant However, their increase in temperature; contrary, weakly became Additionally, formed carry acetyl groups, said hydroxyl groups.
