This idea is about of use from steam distillation of pine oil in presence of different kinds of ionic (inorganic) & organic chemical raw material(s) & product(s). Maybe use from chemical(s) extracted & produced & derivative(s) from wood. Maybe use from natural raw material(s) & product(s) from different kinds of plant(s) & animal(s) as herbal plant(s) & plant(s) & grain(s) & vegetable(s) & oils (lard) substitute of pine oil. This idea (formulas) has uses in these areas applications' of mentioned chemical(s) that are modifying & improvement of properties & solving probably defects. From viewpoint of economic explanation & economic importance & executive necessity & economical & & technological this idea is unique in comparison with current methods (technologies) & exists in market.
Chemistry of wood
The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements (mainly calcium, potassium, sodium, magnesium, iron, and manganese) by weight. Wood also contains sulfur, chlorine, silicon, phosphorus, and other elements in small quantity.
Aside from water, wood has three main components. Cellulose, a crystalline polymer derived from glucose, constitutes about 41–43%. Next in abundance is hemicellulose, which is around 20% in deciduous trees but near 30% in conifers. It is mainly five that are linked in an irregular manner, in contrast to the cellulose. Lignin is the third component at around 27% in coniferous wood vs. 23% in deciduous trees. Lignin confers the hydrophobic properties reflecting the fact that it is based on aromatic rings. These 3 components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. A major focus of the paper industry is the separation of the lignin from the cellulose, from which paper is made. In chemical terms, the difference between hardwood and softwood is reflected in the composition of the constituent lignin. Hardwood lignin is primarily derived from sinapyl alcohol and coniferyl alcohol. Softwood lignin is mainly derived from coniferyl alcohol.
Extractives
Aside from the lignocellulose, wood consists of a variety of low molecular weight organic compounds, called extractives. The wood extractives are fatty acids, resin acids, waxes and terpenes. For example, rosin is exuded by conifers as protection from insects. The extraction of these organic materials from wood provides tall oil, turpentine, and rosin.
