US Patent:

45046662, Mar 12, 1985

Filed:

Jun 4, 1982

Appl. No.:

6/385000

Inventors:

Gary W. Earl - Bexley OH
Howard M. Hickman - Worthington OH

Assignee:

Sherex Chemical Company, Inc. - Dublin OH

International Classification:

C07D21361
C07D25100
C07D23902
C07D24146

US Classification:

546345

Abstract:

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.

Appl. No.:

6/106746

Inventors:

Gary W. Earl - Bexley OH
Howard M. Hickman - Worthington OH

Assignee:

Sherex Chemical Company, Inc. - Dublin OH

International Classification:

C07C13502

US Classification:

564298

Abstract:

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.

International Classification:

C09K 300
H05B 3300

US Classification:

252182

Abstract:

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.
