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 ...
Molar mass: 160.23 g·mol −1 Appearance White solid ... It is one of two monothiols of naphthalene, the other being 1-naphthalenethiol. Synthesis and reactions
A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). [19] The eight carbon atoms that are not shared by the two rings carry one hydrogen atom each.
A practical synthesis involves the tin/HCl-reduction of the naphthalene-1-sulfonyl chloride. [1] 1-Naphthalenethiol can also be prepared from 1-bromonaphthalene by Pd-catalyzed reaction with the silylthiolate i Pr 3 SiSK followed by hydrolysis of the silathioether. [2] It was first prepared from the Grignard reagent generated from 1 ...
In one method, naphthalene is nitrated to give 1-nitronaphthalene, which is hydrogenated to the amine followed by hydrolysis: C 10 H 8 + HNO 3 → C 10 H 7 NO 2 + H 2 O C 10 H 7 NO 2 + 3H 2 → C 10 H 7 NH 2 + 2H 2 O C 10 H 7 NH 2 + H 2 O → C 10 H 7 OH + NH 3. Alternatively, naphthalene is hydrogenated to tetralin, which is oxidized to 1 ...
One way of obtaining compositional information on lubricating base oil is the n-d-M method (ASTM D3238 [6]), an empirical method for determining the carbon type distribution by indicating the percentage of carbons in aromatic structure (%CA), the percentage of carbon in naphthenic structure (%CN) and the percentage of carbon in paraffinic ...
The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of two atoms o oxygen into the other donor. 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.
2,6-Dimethylnaphthalene is mainly used for the preparation of 2,6-naphthalenedicarboxylic acid by oxidation of 2,6-dimethylnaphthalene in the liquid phase. 2,6-Naphthalenedicarboxylic acid is a monomer for the production of high-performance polymers, in particular poly (ethylene-2,6-naphthalene dicarboxylate) or shorter polyethylene naphthalate (PEN).
