Feb 3, 2011 · Naphthalene conversion (naphthalene hydrogenated to tetralin, octalins and decalins) varied from 4 to 96%. This corresponds to a naphthalene hydrogenation rate of 1-24×10 3 mol/(kg cat s). An additional experiment carried out with very low catalyst loading led to a low naphthalene conversion and only tetralin as product.

Jan 1, 2019 · Naphthalene, the simplest bicyclic aromatic ring, is conventionally derived from coal tar. It is a white solid material with strong pungent odour. Naphthalene was first discovered by Scottish chemist, Alexzander garden in 1819. Michael Faraday first reported its molecular formula (C 10 H 8) in 1826 [1]. Conventionally, naphthalene is ...

Naphthalene (91-20-3) is a component of crude oil and is found in petroleum-derived fuels and consumer products. The most common use of naphthalene in consumer products is in the production of mothballs. Naphthalene ingestion can result in acute as well as delayed toxicity. The primary target organs of toxicity are the blood and the eyes.

The toxicity of naphthalene has been well documented and cataractogenic activity has been reported in laboratory animals [4,5]. Naphthalene binds covalently to molecules in liver, kidney and lung tissues, thereby enhancing its toxicity; it is also an inhibitor of mitochondrial respiration [9]. Acute naphthalene poisoning in humans can lead to ...

Jan 1, 2025 · Naphthalene is a two fused benzene ring polycyclic aromatic hydrocarbon. Naphthalene was initially registered with the U.S. Department of Agriculture (USDA) as a pesticide in 1948. The United States Environmental Protection Agency (EPA) issued a registration standard for naphthalene in 1981, and the substance was reregistered by the agency in 2008.

Naphthalene. Heriberto Robles, in Encyclopedia of Toxicology (Second Edition), 2005. Uses. Naphthalene is commonly used in the manufacture of dyes, resins, and mothballs and may also be found in association with coal tar production and in wood preservatives.

The toxic nature of naphthalene is believed to be due to oxidative stress since naphthalene is metabolised to 1,2-naphthalene oxide which depletes GSH pools by S-conjugation (Wells et al., 1989). The lens is not able to directly form naphthalene 1,2-oxide from naphthalene, and naphthalene itself is incapable of cataract induction in cultured ...

Six foldamers with six incorporated decyl chains and two benzene, naphthalene, anthracene, or pyrene units at the ends were revealed by Li et al. to strongly gelate nonpolar and polar solvents. 28 Intramolecular hydrogen bonding stabilizes the rigid helical conformations of the foldamers, whereas large arene units at the ends of the backbones ...
