<unk>  is used mainly as a precursor to other chemicals. The single largest use of<unk>  is the industrial production of phthalic anhydride, although more phthalic anhydride is made from o-xylene. Many azo dyes are produced from<unk> , and so is the insecticide 1-naphthyl-N-methylcarbamate (carbaryl). Other useful agrichemicals include<unk> hthoxyacetic acids. Nadoxolol is a beta blocker. Hydrogenation of<unk>  gives tetralin, which is used as a hydrogen-donor solvent. Alkylation of<unk>  with propylene gives a mixture of diisopropylnaphthalenes, which are useful as nonvolatile liquids used in inks.<unk> sulfonic acids and sulfonates Many<unk> sulfonic acids and sulfonates are useful. Alkyl<unk>  sulfonate are surfactants, The aminonaphthalenesulfonic acids,<unk> s substituted with ethers and sulfonic acids, are intermediates in the preparation of many synthetic dyes. The hydrogenated<unk> s tetrahydronaphthalene (tetralin) and decahydronaphthalene (decalin) are used as low-volatility solvents.<unk>  sulfonic acids are also used in the synthesis of 1-naphthol and 2-naphthol, precursors for various dyestuffs, pigments, rubber processing chemicals and other chemicals and pharmaceuticals.<unk>  sulfonic acids are used in the manufacture of<unk>  sulfonate polymer plasticizers (dispersants), which are used to produce concrete and plasterboard (wallboard or drywall). They are also used as dispersants in synthetic and natural rubbers, and as tanning agents (syntans) in leather industries, agricultural formulations (dispersants for pesticides), dyes and as a dispersant in lead–acid battery plates.<unk>  sulfonate polymers are produced by treating<unk> sulfonic acid with formaldehyde, followed by neutralization with sodium hydroxide or calcium hydroxide. These products are commercially sold as superplasticizers for the production of high strength concrete. Laboratory uses Molten<unk>  provides an excellent solubilizing medium for poorly soluble aromatic compounds. In many cases it is more efficient than other high-boiling solvents, such as dichlorobenzene, benzonitrile, nitrobenzene and durene. The reaction of C60 with anthracene is conveniently conducted in refluxing<unk>  to give the 1:1 Diels–Alder adduct. The aromatization of hydroporphyrins has been achieved using a solution of DDQ in<unk> . Wetting agent and surfactant Alkyl<unk>  sulfonates (ANS) are used in many industrial applications as nondetergent wetting agents that effectively disperse colloidal systems in aqueous media. The major commercial applications are in the agricultural chemical industry, which uses ANS for wettable powder and wettable granular (dry-flowable) formulations, and the textile and fabric industry, which utilizes the wetting and defoaming properties of ANS for bleaching and dyeing operations. As a fumigant<unk>  has been used as a household fumigant. It was once the primary ingredient in mothballs, although its use has largely been replaced in favor of alternatives such as 1,4-dichlorobenzene. In a sealed container containing<unk>  pellets,<unk>  vapors build up to levels toxic to both the adult and larval forms of many moths that attack textiles. Other fumigant uses of<unk>  include use in soil as a fumigant pesticide, in attic spaces to repel animals and insects, and in museum storage-drawers and cupboards to protect the contents from attack by insect pests.<unk>  is a repellent to opossums. Other uses It is used in pyrotechnic special effects such as the generation of black smoke and simulated explosions. It is used to create artificial pores in the manufacture of high-porosity grinding wheels. In the past,<unk>  was administered orally to kill parasitic worms in livestock.<unk>  and its alkyl homologs are the major constituents of creosote.<unk>  is used in engineering to study heat transfer using mass sublimation. It has been proposed as an alternative propellant for cold gas satellite thrusters.
