Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
64 words
A process of preparation of ethersand/or alcohol from olefins or of conversion of ethers and/or alcohols to olefins, the olefins having a double bond attached to a tertiary carbon atom, in the presence of a sulphonated strong acid ion exchange resin catalyst, characterized in that the cation exchange resin catalyst has a pore volume in the range from 0.45 to 0.70 cm 3 /g.
Claim 2
Dependent Claim
64 words
A process of preparation of ethersand/or alcohol from olefins or of conversion of ethers and/or alcohols to olefins, the olefins having a double bond attached to a tertiary carbon atom, in the presence of a sulphonated strong acid ion exchange resin catalyst, characterized in that the cation exchange resin catalyst has a pore volume in the range from 0.45 to 0.70 cm 3 /g.
Claim 3
Dependent Claim
21 words
A process according to claim 1, wherein the catalyst has a pore volume in the range from 0.50 to 0.70 cm3/g.
Claim 4
Dependent Claim
19 words
A process according to claim 1 or 2, wherein the catalyst comprises a matrix of polystyrene cross-linked with divinylbenzene.
Claim 5
Dependent Claim
37 words
A process according to any of claims 1 to 3 , wherein a reaction mixture comprising one or more of such olefins is reacted under such conditions that the product contains one or more ethers and/or alcohols.
Claim 6
Dependent Claim
24 words
A process according to any preceding claim wherein a reaction mixture comprising isobutylene is etherified by reaction with methanol to form methyl tert-butyl ether.
Claim 7
Dependent Claim
24 words
A process according to any of claims 1 to 4, wherein a reaction mixture comprising isobutylene is reacted with water to form tert-butyl alcohol.
Claim 8
Dependent Claim
34 words
A process according to any of claims 1 to 3, wherein a reaction mixture comprising one or more ethers or alcohols is reacted under such conditions that the product contains one or more olefins.
Claim 9
Dependent Claim
56 words
A sulphonated strong acid cation exchange resin for use as a catalyst in the etherification and alcoholification of olefins having a double bond on a tertiary carbon atom or in the reverse reaction involving the formation of such an olefin, characterized by having a pore volume in the range from 0.45 to 0.70 cm J /g.
Claim 10
Dependent Claim
56 words
A sulphonated strong acid cation exchange resin for use as a catalyst in the etherification and alcoholification of olefins having a double bond on a tertiary carbon atom or in the reverse reaction involving the formation of such an olefin, characterized by having a pore volume in the range from 0.45 to 0.70 cm J /g.
Claim 11
Dependent Claim
17 words
A cation exchange resin according to claim 8, which comprises a matrix of polystyrene cross-linked with divinylbenzene.
