HYDROXYLAMINE

Description

Hydroxylamine was first synthesized by Wilhem Clemens Lossen in 1865 in the laboratory of Wilhelm Heinrich Heintz while working in Halle. The Lossen synthesis originally generated hydroxylamine in aqueous solution. Anhydrous hydroxylamine was prepared later by Lobry de Bruyn and Crismer in 1891. The free base is extremely volatile, and industrial-scale production has been fraught with problems, including large explosions at facilities in the United States and Japan. Much of the hydroxylamine produced and transported is in salt form or as a dilute aqueous solution.

The Uses of HYDROXYLAMINE

Hydroxylamine is used as a reducing agent in photography, in synthetic and analytical chemistry, as an antioxidant for fatty acids and soaps, and as a dehairing agent for hides. In addition, hydroxylamine is used in the production of cyclohexanone oxime, an isomer of caprolactam, which is an intermediate in the production of nylon-6. In the semiconductor industry, hydroxylamine can be a component of a solution that dissolves a photoresist following lithography. Hydroxylamine can also be used to selectively cleave asparaginyl-glycine peptide bonds.
