Naphthalene - an overview | ScienceDirect Topics Abstract 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 Individuals deficient in glucose-6-phosphatase
Naphthalene - an overview | ScienceDirect Topics Naphthalene is readily acylated under Friedel–Crafts conditions but generally gives isomeric mixtures of ketone products The relative ratios of these products are highly dependent on factors such as the solvent and catalyst used <B-64MI 306-01> 1-Alkylnaphthalenes and 2-alkylnaphthalenes are acylated in the 2- and 1-positions respectively, and dialkylnaphthalenes are usually acylated at an
Naphthalene - an overview | ScienceDirect Topics Naphthalene (a bicycylic aromatic hydrocarbon) Naphthalene (NAP) is widely used in various commercial and industrial applications including lavatory scent disks, soil fumigants and moth balls Exposure to naphthalene is associated with the development of hemolytic anemia in humans and laboratory animals (Germansky and Jamall, 1988) The toxic manifestations induced by naphthalene appear to
Naphthalene - an overview | ScienceDirect Topics Naphthalene is used as an intermediate in pharmaceutical manufacture and in the production of phthalate plasticizers, naphthalene sulfonates, dyes, insecticides, and synthetic chemicals for leather tanning Crystalline naphthalene is equally employed as a moth repellent
Naphthalene: Risk assessment and environmental health hazard 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 It is a white solid with a mothball like odor
Catalytic two-step preparation of high-purity naphthalene-based . . . In this study, naphthalene-based mesophase pitch (NMP) was prepared using a two-step method involving catalytic synthesis by AlCl 3 and thermal polycondensation The composition, molecular structure, and mesophase transformation of obtained naphthalene-based isotropic pitch (NIP) and NMP, as well as their correlation were investigated
Naphthalene - an overview | ScienceDirect Topics a Naphthalene Naphthalene fed to experimental animals is metabolized in the liver where it is converted to naphthalene-1,2-dihydrodiol This compound is transported to the eye where it is oxidized by a dihydrodehydrogenase to dihydroxynaphthalene, which then autooxidizes to naphthoquinone, which causes a marked decrease in glutathione Formation of a naphthalene cataract is also associated
Naphthalene and its derivatives hydrogenation for hydrogen storage . . . Naphthalene, its methyl derivatives and the products of hydrogenation have the high storage density among the aromatic hydrocarbons (up to 7 3 wt%) which make it the extremely perspective as liquid hydrogen storage carriers
