The Composition and Termicidal Activity of Vinegar from Medang Wood (Cinnamomum sp.) under Different Pyrolysis Temperature

Abstract

The degradation of wood caused by termite infestations is widely recognized as a substantial concern. Therefore, the development of alternative, environmentally-friendly preservation of wood is needed to reduce environmental pollution. The study aimed to analyze the chemical properties of vinegar from medang wood (Cinnamomum sp.) and assess its effectiveness as a termicidal activity against Coptotermes curvignathus. Wood vinegar is made by the pyrolysis method. Pyrolysis is carried out by inserting of air-dried medang wood particles into a pyrolysis reactor and was heated up to the desired temperature of 370, 400, 430°C with the pyrolysis time was 180 minutes. Wood vinegars were tested at various concentrations (2.0-10.0%, v/v) against C. curvignathus in a no-choice test. Result shows that an 8% concentration was required to achieve 100% mortality against C. curvignathus at a 430°C pyrolysis temperature. The lowest mass loss of treated filter paper, 11.99%, was obtained with a 430°C -10.0% combination.

Optimization and Characterization of Liquid Smoke Produced by Terminalia catappa Wood Pyrolysis and its In Vitro Antifungal Activity

“…Oramahi et al (2022a) reported that liquid smoke from Shorea pachyphylla mainly contained formic acid, 2-propanone, acetic acid,4hexadecanoic acid, and guaiacol. Recently, Oramahi et al (2023) investigated that the predominant compounds in liquid smoke gained from Cinnamomum sp. were 1,2-ethanadiol, acetic acid, phenol and methyl ester.…”
