A simple, rapid and efficient procedure for the preparation of di-alkyl, simple phenyl-alkyl and hindered phenyl-alkyl ethers has been developed.Based on the principle of micellar catalysis the method involves alkylation of the alkoxide or the phenoxide ion with an alkyl chloride at 80 deg C in the presence of cationic micelles.For the preparation of phenyl-alkyl ethers normal micelles were used, while for the di-alkyl ethers reverse micelles were more effective.By increasing the ionic strength of the solution the rate of formation of phenyl-alkyl ethers could be increased.

The authors studied the reactions of C//1-C//5 alcohols of normal structure with isobutene, carrying but meticulous analysis of the reaction mixture. Experimental data show that if the rate constants of consumption of pure C//5H//1//1 OH and of its mixture with CH//3OH are compared they are found to be equal within the limits of experimental error. At the same time, the rate constant of TBME Tert-Butyl Methyl Ether accumulation is higher by a factor of 5. 8 in the mixture of alcohols than in pure methanol. These data suggest that this unsual behaviour of TBME and ATBE Alkyl-Tert-Butyl Ethers during their simultaneous formation is due to formation of TBA and 1-pentene.
