hydroxyl amine. It is freely soluble in water. Chemically it is a reducing agent and hence it oxidizes. It reduces ferric ion and converts into ferrous ion. Thermally in presence of water, it decomposes . The details of the above chemical properties with reference to high temperature systems are discussed here.
Properties of Amines 1ï° and 2ï° amines â¢ can form hydrogen bonds with each other and water molecules â¢ can form hydrogen bonds, while amines with less than six carbons are soluble in water because they form hydrogen bonds with water 3ï° amines can only form hydrogen bonds with water molecules 29.
