Acacia mearnsii De Wild. has been cultivated in Brazil mainly for the extraction of tannins from bark, but its wood has been used to complement the demand for hardwood in the pulp and paper industries. However, few studies have been carried out aiming to characterize the chem. composition of the wood lipophilic extracts from this species. Some compounds of these extract may generate sticky deposits in machinery in the paper and pulp mills, known as pitch. In general, woods with a higher content of lipophilic extracts generate more problems and damage caused by pitch deposits. So, this paper details the chem. composition of the lipophilic extracts of A. mearnsii woods of four ages (4, 7, 10 and 13-yr-old) cultivated in Brazil. The wood from 7, 10 and 13-years-old trees showed similar amounts of lipophilic extracts ranging from 0.23 to 0.28%. However, the 4-yr-old wood presented more than twice that value i.e. 0.60%. These lipophilic extracts were analyzed by GC-MS before and after alk. hydrolysis, followed by derivatization. The main chem. classes found were fatty acids (27.1-95.0 mg kg-1), sterols (20.5-55.7 mg kg-1) and aromatic compounds (0.750-13.2 mg kg-1), followed by smaller amounts of long chain aliphatic alc. (0.00-3.46 mg kg-1) and hydrocarbons (0.00-2.62 mg kg-1), before and after hydrolysis. The results showed that the wood extracts from 7, 10 and 13-yr-old trees were similar from the quant. and qual. points of view, indicating that harvests over 7 years of age offer less propensity for pitch problems. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Synthetic Route of C9H12O3
