Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
84 words
A process for manufacturing a catalyst, wherein an aluminum compound of the formula AlX y R.sub.(3-y) where X is halogen, R is a hydrocarbon radical and y is 1, 3/2, or 2, is reacted with a carrier consisting essentially of a mixture of aluminum oxide and boron oxide in proportions by weight of 1: 0.01 to 1: 1, respectively, and wherein the compound of formula AlX y R.sub.(3-y) is used in a sufficient amount to introduce 0.5-20% by weight of halogen into the catalyst.
Claim 2
Dependent Claim
84 words
A process for manufacturing a catalyst, wherein an aluminum compound of the formula AlX y R.sub.(3-y) where X is halogen, R is a hydrocarbon radical and y is 1, 3/2, or 2, is reacted with a carrier consisting essentially of a mixture of aluminum oxide and boron oxide in proportions by weight of 1: 0.01 to 1: 1, respectively, and wherein the compound of formula AlX y R.sub.(3-y) is used in a sufficient amount to introduce 0.5-20% by weight of halogen into the catalyst.
Claim 3
Dependent Claim
15 words
