What is Tetraline used for?

Tetralin is used as a hydrogen-donor solvent, for example in coal liquifaction. It functions as a source of H2, which is transferred to the coal. The partially hydrogenated coal is more soluble.

Is tetrahydronaphthalene aromatic?

1,2,3,4-Tetrahydro-1-phenyl-4-(1-phenylethyl)naphthalene belongs to the class of organic compounds known as tetralins. These are polycyclic aromatic compounds containing a tetralin moiety, which consists of a benzene fused to a cyclohexane.

What is tetralin made of?

Tetralin (1,2,3,4-tetrahydronaphthalene) is a hydrocarbon having the chemical formula C10H12. It is a partially hydrogenated derivative of naphthalene. It is a colorless liquid that is used as a hydrogen-donor solvent….CHEBI:35008.

How do you convert tetralin to naphthalene?

Naphthalene can be converted to the extent of 75–80% into tetralin and decalin on hydrogenating naphthalene fractions containing 42–76% naphthalene at 350° C, under a pressure of 40 atm, and crude feed of 0.3 kg/liter · h. Decalin formation can be reduced by cutting down the hydrogen pressure to 20 atm.

Who discovered naphthalene?

Naphthalene, discovered in 1819 by A. Garden (BUA, 1989), is a natural constituent of coal tar and crude oil, which are major contributors to its presence in the environment. They contain up to 11% and 1.3% of the chemical, respectively (BUA, 1989; O’Neil et al., 2001).

How do you make naphthalene?

The method for the preparation of naphthalene dicarboxylic acid of the invention is conducted by the liquid-state oxidation reaction of dimethylnaphthalene with oxygen in air in the presence of acetic acid solvent using metal catalysts of cobalt and manganese, and using bromine as a reaction initiator, and it is …

What is Basketane used for?

A European patent published in 1988 used basketane, which is a hydrocarbon, as a source material in doping thin diamond layers because of the molecule’s high vapor pressure, carbon ring structure, and fewer hydrogen-to-carbon bond ratio.

How many rings does c10h12?

The Basketane molecule contains a total of 26 bond(s) There are 14 non-H bond(s), 4 four-membered ring(s), 10 six-membered ring(s), 10 eight-membered ring(s) and 4 ten-membered ring(s).

Does sertraline help anxiety?

Taking Zoloft for anxiety Zoloft is the brand name of a generic medication called sertraline. It’s a type of antidepressant called a selective serotonin reuptake inhibitor (SSRI) that treats anxiety by slowing down the reabsorption of serotonin.

What is the purpose of 1, 2, 3, 4-tetrahydronaphthalene?

General description 1,2,3,4-Tetrahydronaphthalene (Tetralin™), a bicyclic hydrocarbon, is a constituent of petroleum and coal tar. It is used in coal liquefaction and as an alternative to turpentine in paints and waxes. Degradation of tetralin by Corynebacterium sp. strain C125, and by pyrolysis have been reported.

How is tetralin similar to naphthalene chemical formula?

Tetralin (1,2,3,4-tetrahydronaphthalene) is a hydrocarbon having the chemical formula C10H12. This molecule is similar to the naphthalene chemical structure except that one ring is saturated.

Which is rarely encountered is dihydronaphthalene or Dialin?

Rarely encountered is dihydronaphthalene ( dialin ). In a classic named reaction called the Darzens tetralin synthesis, named for Auguste Georges Darzens (1926), derivatives can be prepared by intramolecular electrophilic aromatic substitution reaction of a 1-aryl-4-pentene using concentrated sulfuric acid,

Which is the hydride derivative of naphthalene?

Tetralin is an ortho-fused bicyclic hydrocarbon that is 1,2,3,4-tetrahydro derivative of naphthalene. It is an ortho-fused bicyclic hydrocarbon and a member of tetralins. It derives from a hydride of a naphthalene.
