Abstract
The process of the invention provides a method for the selective ortho-alkylation of a phenolic compound with a lower alkane in the presence of a supported nickel oxide catalyst.
Claims9
A process for the selective ortho-alkylation of a phenolic compound of the formula:
- ##STR2## wherein R is a monovalent substituent selected from the group consisting of hydrogen, alkyl, phenyl and alkyl substituted phenyl, said process comprising contacting said phenolic compound with a lower alkane in the vapor phase in the presence of a supported nickel oxide catalyst.
A process for the selective ortho-alkylation of a phenolic compound of the formula:
- ##STR3## wherein R is a monovalent substituent selected from the group consisting of hydrogen, alkyl, phenyl and alkyl substituted phenyl;
- said process comprising contacting said phenolic compound with methane in the vapor phase in the presence of a catalyst which consists essentially of nickel oxide supported on magnesium oxide said process being carried out at a temperature of 200.degree.-500.degree. C. and at atmospheric pressure.
