EXAMPLES; I) Preparation of MTBE (process steps a), b) and c)); The procedure of US 6,657,090 B2 was followed, starting from feedstocks according to tables 1 to 3 of that patent. The yield of MTBE given is calculated based on the amount of MTBE in the product stream, before any purification step or steps. The purity of the MTBE is approximately 84% due to azeotrope formation with 14.5% methanol.; II) Separation of Methanol fro, MTBE-phase (process step d)); The azeotrope was separated into methanol and MTBE by processes known to the skilled person from J.G. Stichlmair, J.R. Fair, "Distillation: Principles and Practice", Wiley-VCH, 2001, p. 238.
