Alkylated naphthalenes are chemical compounds made by the alkylation of naphthalene or its derivatives with an olefin. These compounds are used as synthetic base oils, and are claimed to have improved oxidative stability over some conventional base oils.
Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
1,4-Naphthoquinone or para-naphthoquinone is a quinone derived from naphthalene. It forms volatile yellow triclinic crystals and has a sharp odor similar to benzoquinone. It is almost insoluble in cold water, slightly soluble in petroleum ether, and more soluble in polar organic solvents. In alkaline solutions it produces a reddish-brown color ...
In alkaline conditions, quinones undergo a reversible single-step, two-electron reduction. In neutral conditions, quinones may undergo either a one-proton, two-electron reduction or a two-electron reduction. In aprotic media, quinones undergo two-step reduction without protons. [8] In the first step, a short-lived semiquinone intermediate is ...
Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete.
It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol , but more reactive. Both isomers are soluble in simple alcohols , ethers , and chloroform . 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.
A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.
The systematic name of this enzyme class is naphthalene,NADH:oxygen oxidoreductase (1,2-hydroxylating). Other names in common use include naphthalene dioxygenase , and naphthalene oxygenase . This enzyme participates in 4 metabolic pathways : 1- and 2-methylnaphthalene degradation , naphthalene and anthracene degradation , fluorene degradation ...
