Abstract
Abstract Normal paraffin alkylation with an alkylating agent, i.e. olefin, alkylhalide or alcohol, is effected in the presence of a catalyst of graphite having intercalated in the lattice thereof between about 5 and about 75 weight percent of a Lewis acid. The catalyst utilized in alkylation has additionally intercalated therein between about 0.1 and about 20 weight percent of a Group VIII metal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A process for effecting alkylation of a normal paraffin which comprises contacting said normal paraffin under alkylation conditions with an alkylating agent selected from the group consisting of olefin, alkylhalide and alcohol with a catalyst consisting essentially of graphite having intercalated in the lattice thereof between about 5 and about 75 weight percent of a Lewis acid consisting essentially of a halide of an element of Group IIA, IIIA, IVB, V or VIB and between about 0.1 and about 20 weight percent of a Group VIII metal.
Claim 2
Dependent Claim
87 words
A process for effecting alkylation of a normal paraffin which comprises contacting said normal paraffin under alkylation conditions with an alkylating agent selected from the group consisting of olefin, alkylhalide and alcohol with a catalyst consisting essentially of graphite having intercalated in the lattice thereof between about 5 and about 75 weight percent of a Lewis acid consisting essentially of a halide of an element of Group IIA, IIIA, IVB, V or VIB and between about 0.1 and about 20 weight percent of a Group VIII metal.
Claim 3
Dependent Claim
45 words
The process of claim 1 wherein said alkylation conditions include a temperature between about 0°C and about 150°C, a pressure between about atmospheric and about 500 psig and a mole ratio of said normal paraffin to said alkylating agent between about 1:1 and about 10:1.
Claim 4
Dependent Claim
12 words
The process of claim 1 wherein said Lewis acid is antimony pentafluoride.
Claim 5
Dependent Claim
12 words
The process of claim 1 wherein said Lewis acid is aluminum chloride.
Claim 6
Dependent Claim
12 words
The process of claim 1 wherein said Group VIII metal is platinum.
Claim 7
Dependent Claim
16 words
The process of claim 1 wherein said alkylation is carried out in the presence of hydrogen.
