Disclosed is an improvement in process for oxidizing an aromatic amine to form an aromatic amine oxide wherein a reaction mixture of the aromatic amine and a peracid is formed and maintained under non-aqueous conditions at a temperature and for a time adequate until substantially all of the aromatic amine is formed into said aromatic amine oxide. The provision for eliminating water from the reaction mixture leads to near quantitative yields of aromatic amine oxide.

High yield preparation of aromatic amine oxides

Disclosed is a method for stabilizing an aqueous tertiary di-(.beta.-hydroxy organo) amine oxide which comprises incorporating therein a stabilizing proportion of an amine oxide salt which is the reaction product of a tertiary amine oxide and a protic acid.

Stabilization of aqueous tertiary di-.beta.-hydroxy amine oxides

A polyol composition consisting essentially of a homogenous liquid admixture of propylene glycol and a diol obtained by alkoxylating a propylene glycol dispersion of 3,3',5,5'-tetrabromobisphenol A with ethylene oxide, propylene oxide or mixtures thereof. These polyol compositions are useful in preparing fire and chemical resistant thermosetting resinous compositions.

Diol compositions

Disclosed are tertiary amine oxides which comprise an amine oxide nucleus substituted with an organic group and with two hydroxy groups which have carbon atoms in at least the .alpha., .beta. and .gamma. positions, a hydroxyl group on the .beta.-carbon atom, and have an effective chain length of at least 4 carbon atoms, said amine oxide being capable of being provided in ostensibly anhydrous form and being capable of being made at a concentration by weight of at least about 80% by oxidizing the corresponding tertiary amine with an oxidizing agent without solvent and without gelling during said oxidation.
