Claim 1
Independent Claim
55 words
A composition comprising a crystalline copper aluminum borate having the significant X-ray diffraction lines set forth in Table A and from about 0.05 to 50 wt % of at least one compound selected from the group consisting of an alkali metal and alkaline earth metal compound based on the weight of the copper aluminum borate.
Claim 2
Dependent Claim
55 words
A composition comprising a crystalline copper aluminum borate having the significant X-ray diffraction lines set forth in Table A and from about 0.05 to 50 wt % of at least one compound selected from the group consisting of an alkali metal and alkaline earth metal compound based on the weight of the copper aluminum borate.
Claim 3
Dependent Claim
13 words
The composition of claim 1, wherein the dopant is an alkali metal compound.
Claim 4
Dependent Claim
20 words
The composition of claim 2, wherein the alkali metal dopant comprises an oxide or compound readily reducible to the oxide.
Claim 5
Dependent Claim
93 words
A composition comprising finely divided zero valent copper on a support comprising at least one crystalline aluminum borate selected from the group consisting of Al 4 B 2 O 9 and cooper aluminum borate and from about 0.5 to 50 wt % dopent based on the weight of the crystalline aluminum borate comprising an alkali metal or alkaline earth metal compound wherein said finely divided zero valent copper and crystalline aluminum borate composition are formed by the reduction of copper aluminum borate having the significant X-ray diffraction lines set forth in Table A.
