Thanks for your response, prof. Allen. I'll formulate an inquiry to Mohammed Farid as you suggest. You mentioned Thai railway application. I saw somewhere that German railways are using SVO in some of their shunting engines. The encouraging part of your message is you are reacting at 60C and that this is near methanol boiling point. That implies you are succeeding at atmospheric pressure. Do you use conc. sulphuric acid first stage? I agree meth recovery is so simple that using excess is not really a problem.
