Experimental data show that Mobil Research and Development Corp.'s new gasoline synthesis from methanol on zeolites of pore dimensions intermediate between faujasites and zeolite A (described in patent literature) gives similar product distributions from methanol, tert.-butanol and 1-heptanol. The shape-selective zeolite produces essentially no hydrocarbons above C/sub 13/, mainly isoparaffins, isoolefins, and methylsubstituted benzenes. Xylenes are produced in equilibrium amounts, but steric hindrance is evident in the trimethyl- and tetramethylbenzenes. Product distributions from reactions at various temperatures (250 to 550/sup 0/C) and feed rates (1-1080 volume methanol per volume catalyst per hour) suggested sequential conversion of methanol to dimethylether to C/sub 2/-C/sub 5/ olefins to paraffins, aromatics, and higher olefins. A methylene insertion mechanism seems most likely. The product distributions from the reactions of methanethiol, propanal, methylal, and acetone are also presented and discussed.
