Claims18
A method of decomposing an organic azide, comprising:
- allowing an organic azide to contact a catalyst that comprises a transition metal halide, wherein the organic azide has the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group.
A method of decomposing an organic azide, comprising:
- allowing an organic azide to contact a catalyst that comprises an iron halide or a mixture of iron halide and a second catalyst, wherein the organic azide has the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group.
A method of decomposing an organic azide, comprising:
- allowing an organic azide to contact a catalyst that comprises a transition metal chloride, wherein the organic azide has the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group.
A method of decomposing an organic azide, comprising:
- allowing an organic azide to contact a catalyst that comprises an iron chloride in combination with a second catalyst, wherein the organic azide has the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group.
A method of decomposing an organic azide, comprising:
- allowing an organic azide to contact a catalyst that comprises a metal halide, main group halide, mixed metal-main group halide, or mixture thereof, wherein the organic azide has the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group, and wherein the catalyst is dispersed on a support.
A composition of matter comprising:
- (a) an organic azide having the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group;
- and
- (b) a catalyst capable of decomposing the organic azide, said catalyst comprising a transition metal halide.
A composition of matter comprising:
- (a) an organic azide having the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group;
- and
- (b) a catalyst capable of decomposing the organic azide, said catalyst comprising an iron halide or a mixture of iron halide and a second catalyst.
A composition of matter comprising:
- (a) an organic azide having the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group;
- and
- (b) a catalyst capable of decomposing the organic azide, said catalyst comprising a transition metal chloride.
A composition of matter comprising:
- (a) an organic azide having the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group;
- and
- (b) a catalyst capable of decomposing the organic azide, said catalyst comprising an iron chloride in combination with a second catalyst.
A composition of matter comprising:
- (a) an organic azide having the formula R—N3, where R is an organic group selected from the group consisting of alkyl, alkyl amino, nitrogen-containing heterocyclic-substituted alkyl, and alkyl amine substituted with at least one alkyl azide group;
- and
- (b) a catalyst capable of decomposing the organic azide, said catalyst comprising at least one metal halide, main group halide, mixed metal-main group halide, or mixture thereof;
- and wherein the catalyst is dispersed on a support.
