The objective is to formulate a process for obtaining high yields of ether products while minimizing the polymerization and carbon alkylation side reactions. 2-methyl-2-butene was chosen as the alkylating agent, and p-cresol is the first model compound. The effect of temperature on the products from 4 h reactions in 40% sulfuric acid was measured. The values reported are those of equilibrium since ether formation is a reversible process. Results indicate that equilibrium in the forward direction is favored at lower temperatures. Reduced temperatures also decrease the amount of ring alkylation. The use of 10% sulfuric acid also reduced ring alkylation, but the rate of ether formation is reduced. Thus, increasing the olefin/phenol ratio can be expected to increase ether formation. 12 figures, 9 tables.
