The global methanol and MTBE (methyl tertiary butyl ether) market is reviewed. The global methanol industry has historically tended toward extreme fluctuations. The present situation also appears to contain a great deal of volatility. The total methanol demand for formaldehyde production is expected to increase by about 7.2% in 1991-1995. But U.S. MTBE demand remains unknown. Demand in Europe, Far East and Asia, South America and other regions is assessed. Nevertheless, uncertainty remains.
