Suberic Acid
Suberic acid, also octanedioic acid, is a dicarboxylic acid In organic chemistry, a dicarboxylic acid is an organic compound containing two carboxyl groups (). The general molecular formula for dicarboxylic acids can be written as , where R can be aliphatic or aromatic.Boy Cornils, Peter Lappe "Dicarbox ..., with formula C8H14O4.

Dicarboxylic Acid
In organic chemistry, a dicarboxylic acid is an organic compound containing two carboxyl groups (). The general molecular formula for dicarboxylic acids can be written as , where R can be aliphatic or aromatic.Boy Cornils, Peter Lappe "Dicarboxylic Acids, Aliphatic" in Ullmann's Encyclopedia of Industrial Chemistry 2014, Wiley-VCH, Weinheim. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids. Dicarboxylic acids are usually colorless solids. A wide variety of dicarboxylic acids are used in industry. Adipic acid, for example, is a precursor to certain kinds of nylon. A wide variety of dicarboxylic acids are found in nature. Aspartic acid and glutamic acid are two amino acids found in all life. Succinic and fumaric acids are essential for metabolism. A large inventory of derivatives are known including many mono- and diesters, amides, etc. Partial list of saturated dicarboxylic acids Some common or illustrative examples : ...

Cork (material)
Cork is an impermeable buoyant material. It is the phellem layer of bark tissue which is harvested for commercial use primarily from '' Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell. Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork is made up of suberin (average of about 40%), lignin (22%), polysaccharid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
