Abstract
Acid activated clay catalysts (bentonite or montmorillonite) used in the alkylation of phenols with olefinic hydrocarbons are reactivated by separating the catalyst and treating with a compound which may be an olefinic hydrocarbon of 3-18 carbon atoms, an alkyl alcohol of 1-6 carbon atoms, ketones of 3-11 carbon atoms, ethers of 6-10 carbon atoms, esters of alkyl alcohols of 1-6 carbon atoms with saturated and unsaturated organic mono-carboxylic acids of 2-17 carbon atoms, or organic acids of 2-3 carbon atoms at a temperature ranging from ambient to 200 DEG C. Alternatively the catalyst may be regenerated in situ by adding one of the above compounds near the completion of the alkylation process and further treating at 70-150 DEG C. for 10-20 minutes.ALSO:In the alkylation of phenolic compounds with olefinic hydrocarbons using acid activated clay catalysts (bentonite or montmorillonite) the activity of the catalyst is maintained by separating the catalyst and treating with a compound which may be an olefinic hydrocarbon of 3-18 carbon atoms, an alkyl alcohol of 1-6 carbon atoms, ketones of 3-11 carbon atoms, ethers of 6-10 carbon atoms, esters of alkyl alcohols of 1-6 carbon atoms with saturated and unsaturated organic mono-carboxylic acids of 2-17 carbon atoms, or organic acids of 2-3 carbon atoms at a temperature ranging from ambient to 200 DEG C. A modification of the process comprises the addition of one of the above compounds to the reaction vessel near the completion of the reaction followed by heating at 70-150 DEG C. for 10-20 minutes.ALSO:Acid activated clay catalysts (bentonite or montmorillonite) used in the alkylation of phenols with olefinic hydrocarbons are reactivated by separating the catalyst and treating with a compound which may be an olefinic hydrocrabon of 3-18 carbon atoms, an alkyl alcohol of 1-6 carbon atoms, ketones of 3-11 carbon atoms, ethers of 6-10 carbon atoms, esters of alkyl alcohols of 1-6 carbon atoms with saturated and unsaturated organic monocarboxylic acids of 2-17 carbon atoms, or organic acids of 2-3 carbon atoms at a temperature ranging from ambient to 200 DEG C.
