Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A method of preparing a supported metal phthalocyanine catalyst which comprises successively impregnating a solid adsorbent carrier material with a solution of an alkali metal phthalocyanine and with a metal salt solution comprising a metal exchangeable with said alkali metal, said metal salt being in sufficient amount to provide an exchange metal/alkali metal phthalocyanine weight ratio of from about 1.5:1 to about 3.0:1 and effecting a substantially complete metal cationic exchange between said metal salt and said alkali metal phthalocyanine.
Claim 2
Independent Claim
80 words
A method of preparing a supported metal phthalocyanine catalyst which comprises successively impregnating a solid adsorbent carrier material with a solution of an alkali metal phthalocyanine and with a metal salt solution comprising a metal exchangeable with said alkali metal, said metal salt being in sufficient amount to provide an exchange metal/alkali metal phthalocyanine weight ratio of from about 1.5:1 to about 3.0:1 and effecting a substantially complete metal cationic exchange between said metal salt and said alkali metal phthalocyanine.
Claim 3
Dependent Claim
26 words
The method of claim 1 further characterized in that the carrier material is initially impregnated with said phthalocyanine solution and thereafter with said metal salt solution.
Claim 4
Dependent Claim
16 words
The method of claim 1 further characterized in that said alkali metal phthalocyanine is dilithium phthalocyanine.
Claim 5
Dependent Claim
23 words
The method of claim 1 further characterized in that said solution of an alkali metal phthalocyanine is an alcoholic solution of dilithium phthalocyanine.
Claim 6
Dependent Claim
27 words
The method of claim 1 further characterized in that said supported metal phthalocyanine catalyst is a supported copper phthalocyanine catalyst and said metal salt is cupric chloride.
Claim 7
Dependent Claim
27 words
The method of claim 1 further characterized in that said supported metal phthalocyanine catalyst is a supported cobalt phthalocyanine catalyst and said metal salt is cobalt chloride.
Claim 8
Dependent Claim
35 words
The method of claim 1 further characterized in that said metal salt and said alkali metal phthalocyanine are employed in an amount to provide a catalyst comprising from about 0.5 to about 1.5% metal phthalocyanine.
Claim 9
Dependent Claim
16 words
The method of claim 1 further characterized in that said carrier material is an activated charcoal.
Claim 10
Dependent Claim
17 words
The method of claim 1 further characterized in that said carrier material is a refractory inorganic oxide.
Claim 11
Dependent Claim
16 words
The method of claim 1 further characterized in that said carrier material is an activated alumina.
