2-(Benzotriazol-2-Yl)-4-Alkyl-6-(2-Hydroxy-3-Benzoyl-6-Alko Xybenzyl)Phenols And Stabilized Compositions
view source
US Patent:

53876911, Feb 7, 1995
Filed:

Mar 5, 1993
Appl. No.:

8/026961
Inventors:

Robert A. Falk - New City NY
John J. Luzzi - Carmel NY
Gregory R. Coughlin - Poughkeepsie NY
Assignee:

Ciba-Geigy Corporation - Ardsley NY
International Classification:

C07D24920
US Classification:

548257
Abstract:

2-(Benzotriazol-2-yl)-4-alkyl-6-(2-hydroxy-3-benzoyl-6-alkoxybenzyl)phenols am prepared by reacting a Mannich base of a 2-(2-hydroxy-5-alkylphenyl)-2H-benzotriazole with a 2-hydroxy-4-alkoxybenzophenone. The hybrid products exhibit outstanding efficacy in protecting organic substrates from light-induced deterioration as well as good resistance to loss by volatilization or exudation during the processing of stabilized compositions at elevated temperatures.

US Patent:

39364569, Feb 3, 1976
Filed:

Jul 16, 1973
Appl. No.:

5/379901
Inventors:

Chester E. Ramey - Spring Valley NY
John J. Luzzi - Carmel NY
Assignee:

Ciby-Geigy Corporation - Ardsley NY
International Classification:

C07D24102
US Classification:

260268DK
Abstract:

Substituted piperazine dione oxyls and hydroxides are stabilizers for synthetic polymeric materials normally subject to deterioration caused by ultraviolet light. The compounds may be prepared by first preparing a substituted piperazine dione with subsequent oxidation of the piperazine dione to yield the oxyl and reduction of the oxyl to yield the hydroxide derivative. Polymeric compositions containing these stabilizers may also contain a hindered phenolic compound. A typical embodiment is 15-n-octadecyl-7-oxyl-7,15-diazadispiro[5,1,5,3]hexadecane-14,16-dione.

Filed:

Sep 22, 1977
Appl. No.:

5/835759
Inventors:

Chester E. Ramey - Spring Valley NY
John J. Luzzi - Carmel NY
Assignee:

Ciba-Geigy Corporation - Ardsley NY
International Classification:

C07D24108
US Classification:

260 458N
Abstract:

Substituted piperazine diones are stabilizers for synthetic polymeric materials normally subject to deterioration caused by ultraviolet light. The compounds are prepared by the alkylation reaction between a substituted piperazine dione and an organic halide. Polymeric compositions containing these stabilizers may also contain a hindered phenolic compound. A typical embodiment is 15,15'-dodecamethylene-bis(7,15-diazadispiro[5,1,5,3]hexadecane-14,16-dion e).
