Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
In a hydrocarbon conversion process selected from the group consisting of isomerization and alkylation wherein at least one hydrocarbon is contacted with a conversation catalyst under conversion conditions, the improvement comprising contacting aid hydrocarbon with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from the group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at a temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 2
Dependent Claim
107 words
In a hydrocarbon conversion process selected from the group consisting of isomerization and alkylation wherein at least one hydrocarbon is contacted with a conversation catalyst under conversion conditions, the improvement comprising contacting aid hydrocarbon with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from the group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at a temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 3
Dependent Claim
11 words
The process of claim 1 wherein said hydrocarbon conversion is isomerization.
Claim 4
Dependent Claim
11 words
The process of claim 1 wherein said hydrocarbon conversion is alkylation.
Claim 5
Dependent Claim
105 words
In a polymerization method wherein a monomer or mixture or monomers is contacted under polymerization conditions with a free radical polymerization catalyst, the improvement comprising contacting said monomer or mixture of monomers with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from the group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at a temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 6
Dependent Claim
105 words
In a polymerization method wherein a monomer or mixture or monomers is contacted under polymerization conditions with a free radical polymerization catalyst, the improvement comprising contacting said monomer or mixture of monomers with a catalyst prepared by reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from the group consisting of aluminum halides, antimony halides and mixtures thereof and a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at a temperature and for a time sufficient for said Lewis acid to react with at least a portion of said surface hydroxyl groups.
Claim 7
Dependent Claim
19 words
The polymerization method of claim 3 wherein a mixture of styrene and methyl methacrylate is contacted with said catalyst.
