A major use of sawdust is for particleboard; coarse sawdust may be used for wood pulp. Sawdust has a variety of other practical uses, including serving as a mulch, as an alternative to clay cat litter, or as a fuel. Until the advent of refrigeration, it was often used in icehouses to keep ice frozen during the summer.
It is a colorless liquid, although commercial samples are often brown. It has an aldehyde group attached to the 2-position of furan . It is a product of the dehydration of sugars, as occurs in a variety of agricultural byproducts, including corncobs , oat , wheat bran , and sawdust .
A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.
Production facilities for this process are in The Netherlands and is known under the trade name “NobelWood”. From agricultural waste, like sugarcane bagasse, furfuryl alcohol is manufactured. Theoretically this alcohol can be from any fermented bio-mass waste and therefore can be called a green chemical.
An example in liquids is the miscibility of water and ethanol as they mix in all proportions. [1] By contrast, substances are said to be immiscible if the mixture does not form a solution for certain proportions. For one example, oil is not soluble in water, so these two solvents are immiscible
The organic matter in the black liquor is made up of water/alkali soluble degradation components from the wood. [1] Lignin is degraded to shorter fragments with sulphur content at 1-2% and sodium content at about 6% of the dry solids. The extractives gives tall oil soap and crude turpentine.
