Abstract

The dissolution of wood lignin in the alkali solution were analyzed for two fast growing species, sengon (Paraserianthes falcataria) dan leda (Eucalyptus deglupta). Wood samples were extracted in 1% sodium hydroxide solution in cold and hot temperatures for 24 and 1 h, respectively. Extractable substances content, permanganate consumption (expressed as assumed lignin content) were analyzed from the filtrates, lignin content and diastereomeric of β-O-4 structure were analyzed from the wood residue after alkali extraction. The extracted substances from both of wood in hot alkali was higher than in cold alkali solution, although the time of cold alkali extraction was much longer that hot alkali extraction. Assumed lignin content in the extract was quite high in both samples which were 34.4-42.9% and 35.5-39.8% including 2,15-2,29% dan 1,04-1,32% of lignin for cold and hot alkali extraction, respectively. The changes in stereo isomeric form, erythro and threo, of β-O-4 structure of lignin in wood residue indicated that partial depolimerization of lignin was takec place during alkali treatment.

Abstract

Binuang bini (Octomeles sumatrana) and binuang laki (Duabanga moluccana) are fast growing species that have the potential to be developed as engineered wood products. However, previous studies have shown that both wood species have high contact angle values due to the extractive content and the high acidity. Therefore, this study aimed to examine the effect of hot water extraction (HWE) pretreatment to eliminate these limiting factors. The results proved that HWE pretreatment statistically significantly decreased the contact angle of binuang bini wood but not for binuang laki wood. HWE pretreatment resulted in a decrease in the levels of hot water-soluble extractive content and degradation of other wood chemical components. The different effectiveness of HWE pretreatment on binuang bini and binuang laki wood on improving the contact angle is influenced by differences in the quantity and quality of extractive substances as well as differences in the anatomical structure characteristics of these species.
