GENERAL DESCRIPTION AND APPLICATIONS
Hydrazine (anhydrous) is a clear, fuming, corrosive liquid with an ammonia-like odor; melting at 1.4 C, boiling at 113.5 C, specific gravity 1.011. It is very soluble in water and soluble in alcohol. It decomposes on heating or exposure to UV to form ammonia, hydrogen, and nitrogen, which may be explosive with a blue flame when catalysed by metal oxides and some metals such as platinum or Raney nickel. It is prepared from ammonia with chloramine in the presence of glue or gelatin (to inhibit decomposition of the hydrazine by unreacted oxidants) as the hydrate form usually (100% monohydrate contains 64% by weight hydrazine). Hydrazine is also prepared from sodium hypochlorite with urea in the presence of glue or gelatin. Hydrazine is used as a component in jet fuels because it produce a large amount of heat when burned. Hydrazine is used as an oxygen scavenger for boiler feed water to prevent corrosion damage. Hydrazine is used as a reducing agent for the recovery of precious metals and as a chain extender in urethane coatings. Hydrazine is dibasic and very reactive. It and its derivatives have active applications in organic synthesis for agrochemicals, pharmaceuticals and stabilizers, polymerization catalysts, flame-retardants, blowing agents for plastics. Hydrazone is a compound containing the group -NH·N:C-. It is formed from a condensation reaction aldehydes or ketones with hydrazines (commonly phenylhydrazine). It is used as a an exotic fuel. Aromatic hydrazones are used to form indoles by a ring closure reaction (Fischer synthesis). Hydrazones and hydrazines are converted to aldehydes and ketones to corresponding hydrocarbons by heating the carbonyl compound with sodium ethoxide (Wolf-Kishner reduction). Benzophenone Hydrazone is used as a intermediate in the manufacture of UV absorbers and heterobicyclic organic compounds and pharmaceuticals (such as diphenhydramine).

GENERAL DESCRIPTION OF BENZOPHENONE
Benzophenone, an aromatic ketones (diphenyl ketone), is an important compound in organic photochemistry and perfumery as well as in organic synthesis. It is a white crystalline substance with rose-like odor; insolube in water; melting point 49 C; boiling point 305 - 306 C. Benzophenone is used as a constituent of synthetic perfumes and as a starting material for the manufacture of dyes, pesticides and drugs (especially anxiolytic and hypnotic drugs). Benzophenone is used as a photoinitiator of UV-curing applications in inks, adhesive and coatings, optical fiber as well as in printed circuit boards. Photoinitiators are compounds that break down into free radicals upon exposure to ultraviolet radiation. Photoinitiators undergo a unimolecular bond cleavage upon irradiation to yield free radicals (benzoin esters; benzil ketals; alpha-dialkoxy acetophenones; alpha-hydroxy alkylphenones; alpha-amino alkylphosphine; acylphosphine oxides). Another type of photoinitiators undergo a bimolecular reaction where the excited state of the photoinitiator interacts with a second molecule (a coinitiator) to generate free radicals (benzophenones, amines; thioxanthones, titanocenes). Ultraviolet radiation has more energy than visible light, and thus degrade the physical properties such as the appearance of organic substances and plastics. Benzophenones can act as optical filters or deactivate substrate molecules that have been excited by light for the protection polymers and organic substances. They, cosmetic grades, are used as sunscreen agents to reduce skin damage by blocking UV-A, B.
