2,6-Naphthalenedicarboxylic Acid
2,6-Naphthalenedicarboxylic acid is an organic compound with the formula C10H6(CO2H)2. This colorless solid is one of several isomers of naphthalenedicarboxylic acid. It is a precursor to the high performance polyester polyethylene naphthalate (PEN, poly(ethylene-2,6-naphthalene dicarboxylate)). It is also used in the synthesis of some metal-organic frameworks. Preparation The conjugate base of 2,6-naphthalenedicarboxylic acid, when heated, isomerizes to the 1,6-isomer, which is readily converted to 1,6-naphthalenedicarboxylic acid. It is also produced by oxidation of 2,6-diisopropylnaphthalene 2,6-Diisopropylnaphthalene (2,6-DIPN) is an organic compound with the formula C10H6(i-Pr)2 (where i-Pr = isopropyl). 2,6-DIPN is one of several isomers of diisopropylnaphthalene. It is a white or colorless solid.. 2,6-DIPN is plant growth regula ..... References Dicarboxylic acids Naphthalenes {{aromatic-stub ...

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Polyethylene Naphthalate
Polyethylene naphthalate (poly(ethylene 2,6-naphthalate) or PEN) is a polyester derived from naphthalene-2,6-dicarboxylic acid and ethylene glycol. As such it is related to poly(ethylene terephthalate), but with superior barrier properties. Production Two major manufacturing routes exist for polyethylene naphthalate (PEN), i.e. an ester or an acid process, named according to whether the starting monomer is a diester or a diacid derivative, respectively. In both cases for PEN, the glycol monomer is ethylene glycol. Solid-state polymerization (SSP) of the melt-produced resin pellets is the preferred process to increase the average molecular weight of PEN. Applications Because it provides a very good oxygen barrier, it is well-suited for bottling beverages that are susceptible to oxidation, such as beer. It is also used in making high performance sailcloth. Significant commercial markets have been developed for its application in textile and industrial fibers, films, and foamed ar ...

2,6-Diisopropylnaphthalene
2,6-Diisopropylnaphthalene (2,6-DIPN) is an organic compound with the formula C10H6(i-Pr)2 (where i-Pr = isopropyl). 2,6-DIPN is one of several isomers of diisopropylnaphthalene. It is a white or colorless solid.. 2,6-DIPN is plant growth regulator Plant hormone (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, from embryogenesis, the regulation of organ size, .... It helps inhibit the sprouting of potatoes during storage, especially in combination with chlorpropham. 2,6-DIPN is intended for use in the manufacturing of products intended to prevent sprouting of stored potatoes. 2,6-DIPN can be oxidized to 2,6-naphthalenedicarboxylic acid. Toxicity No risks to human health are expected from exposure. References {{DEFAULTSORT:Diisopropylnaphthalene, 2,6- Naphthalenes Isopropyl compounds Hydrocarbons ...

Dicarboxylic Acids
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. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids. Dicarboxylic acids are used in the preparation of copolymers such as polyamides and polyesters. The most widely used dicarboxylic acid in the industry is adipic acid, which is a precursor in the production of nylon. Other examples of dicarboxylic acids include aspartic acid and glutamic acid, two amino acids in the human body. The name can be abbreviated to diacid.
