Product Details:

o-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C₆H₄(CH₃)₂, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o-Xylene is a colourless slightly oily flammable liquid.^[7]

Production and use[edit]

Petroleum contains about one weight percent xylenes. Most o-xylene is produced by cracking petroleum, which affords a distribution of aromatic compounds, including xylene isomers. m-Xylene is isomerized to o-xylene. Net production was approximately 500,000 tons in the year 2000.

o-Xylene is largely used in the production of phthalic anhydride, which is a precursor to many materials, drugs, and other chemicals.^[7] Related to their easy oxidation, the methyl groups are susceptible to halogenation. When treated with elemental bromine, these groups are brominated, yielding xylylene dibromide:^[8]

Product Details:

Acetonitrile, an aliphatic nitrile, is widely used as an organic solvent and intermediate in organic syntheses.^[1] It is transparent to UV-visible light, which makes it highly applicable in spectrophotometric and fluorimetric techniques. MeCN is utilized as a mobile phase component in many chromatographic techniques, due to its low viscosity, high elution strength and miscibility in water. It also plays a major role as an extractant medium in liquid-liquid extraction, solid-phase extraction or microextraction.^[2]

Application

Acetonitrile may be used as a solvent to prepare:
• 1,2-Azidoalcohols and 1,2-azidoamines via cerium(III) chloride assisted ring opening of epoxides and aziridines by sodium azide.^[3]
• Cyano-bearing indolinones by oxidative arylalkylation of olefins in the presence of palladium catalyst.^[4]

It may also be used as a reactant to synthesize:
• Bis (diphenylphosphino) acetonitrile by reacting with n-butyllithium and then with chlorodiphenylphosphine.^[5]
• β-Acetamido ketones via coupling reaction with ketones or ketoesters and aldehydes in the presence of cobalt(II) chloride.^[6]

Product Details:

1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C₄H₉OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.

1-Butanol occurs naturally as a minor product of the ethanol fermentation of sugars and other saccharides^[6] and is present in many foods and drinks.^[7][8] It is also a permitted artificial flavorant in the United States,^[9] used in butter, cream, fruit, rum, whiskey, ice cream and ices, candy, baked goods, and cordials.^[10] It is also used in a wide range of consumer products.^[7]

The largest use of 1-butanol is as an industrial intermediate, particularly for the manufacture of butyl acetate (itself an artificial flavorant and industrial solvent). It is a petrochemical derived from propylene. Estimated production figures for 1997 are: United States 784,000 tonnes; Western Europe 575,000 tonnes; Japan 225,000 tonnes.^[8]

Product Details:

Hydrazine is an inorganic compound with the chemical formula N2H4. It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic unless handled in solution as, for example, hydrazine hydrate (N2H4·xH2O).

Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion.^[8] As of 2000, approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) were manufactured worldwide per year.^[9]

Hydrazines refer to a class of organic substances derived by replacing one or more hydrogen atoms in hydrazine by an organic group.^[9]

Etymology[edit]

The nomenclature is a bi-valent form, with prefix hydr- used to indicate the presence of hydrogen atoms and suffix beginning with -az-, from azote, the French word for nitrogen.

Applications[edit]Gas producers and propellants[edit]

The largest use of hydrazine is as a precursor to blowing agents. Specific compounds include azodicarbonamide and azobisisobutyronitrile, which produce 100–200 mL of gas per gram of precursor. In a related application, sodium azide, the gas-forming agent in air bags, is produced from hydrazine by reaction with sodium nitrite.^[9]

Hydrazine is also used as a long-term storable propellant on board space vehicles, such as the Dawn mission to Ceres and Vesta, and to both reduce the concentration of dissolved oxygen in and control pH of water used in large industrial boilers. The F-16 fighter jet, Eurofighter Typhoon,^[10] Space Shuttle, and U-2 spy plane use hydrazine to fuel their Emergency Start System in the event of an engine stall.^[11]

Precursor to pesticides and pharmaceuticals[edit]Fluconazole, synthesized using hydrazine, is an antifungal medication.

Hydrazine is a precursor to several pharmaceuticals and pesticides. Often these applications involve conversion of hydrazine to heterocyclic rings such as pyrazoles and pyridazines. Examples of commercialized bioactive hydrazine derivatives include cefazolin, rizatriptan, anastrozole, fluconazole, metazachlor, metamitron, metribuzin, paclobutrazol, diclobutrazole, propiconazole, hydrazine sulfate,^[12] diimide, triadimefon,^[9] and dibenzoylhydrazine.

Hydrazine compounds can be effective as active ingredients in insecticides, miticides, nematicides, fungicides, antiviral agents, attractants, herbicides, or plant growth regulators.^[13]
