AMINE OXIDE; amıne oxide; AMİNE OXİDE; AMIN OKSIDE; AMİN OKSİDE; amın oksıde; amin okside; amın oksıt; AMIN OKSIT; amin oksit; AMİN OKSİT; N-oxide; N oxıde; N oxide; N oksıt; N oksit; N-methylmorpholine N-oxide

An amine oxide, also known as amine-N-oxide and N-oxide, is a chemical compound that contains the functional group R3N+-O-, an N-O bond with three additional hydrogen and/or hydrocarbon side chains attached to N.  Sometimes it is written as R3N›O or, wrongly, as R3N=O. In the strict sense the term amine oxide applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary amines. Examples of amine oxides include pyridine N-oxide, a water-soluble crystalline solid with melting point 62-67 °C, and N-methylmorpholine N-oxide, which is an oxidant. Amine oxides are surfactants commonly used in consumer products such as shampoos, conditioners, detergents, and hard surface cleaners. Alkyl dimethyl amine oxide (chain lengths C10-C16) is the most commercially used amine oxide. They are considered a high production volume class of compounds in more than one member country of the Organisation for Economic Co-operation and Development (OECD);  They serve as stabilizers, thickeners, emollients, emulsifiers and conditioners with active concentrations in the range of 0.1-10%.[1] The remainder (< 5%) is used in personal care, institutional, commercial products and for unique patented uses such as photography. Amine oxides are used as protecting group for amines and as chemical intermediates. Long-chain alkyl amine oxides are used as nonionic surfactants and foam stabilizers. Amine oxides are highly polar molecules have a polarity close to that of quaternary ammonium salts. Small amine oxides are very hydrophilic and have an excellent water solubility and a very poor solubility in most organic solvents. Amine oxides are weak bases with a pKa of around 4.5 that form R3N+-OH, cationic hydroxylamines, upon protonation at a pH below their pKa. Amine oxides are prepared by oxidation of tertiary amines or pyridine analogs with hydrogen peroxide (H2O2), Caro's acid or peracids like mCPBA in N-oxidation. An amine oxide, also known as amine-N-oxide and N-oxide, is a chemical compound that contains the functional group R3N+-O-, an N-O bond with three additional hydrogen and/or hydrocarbon side chains attached to N.
