Methanol. Analysis for methanol content will only be required during periods when methanol is being injected for operational reasons. Buyer will be advised when used. Methanol content will be determined using a mutually agreed procedure. .
Methanol. The gas will not contain methanol in concentration detectable by the test method, unless agreed otherwise.
Methanol. This property precludes the formation of products derived from photoinduced electron-transfer from the solvent to the electron-accepting substrate (See Chap- ter 2). The reactions were carried out at 2°C; at that temperature, during the time of irradiation, there is no significant thermolytic product formation (< 5%). The results of the photolyses are summarised in Table 1. Table 2 contains the ortho, meta, para ratios of the methoxybiphenyls. Scheme 2: Photolysis of compounds 1-7.

Methanol. Methanol is the simplest member of the group of alcohols with the molecular formula CH3OH making it rich in hydrogen with only a single carbon atom. It is a clear colourless liquid with a density of 0.79 kg/l. It is today mainly produced from fossil sources (natural gas), but can also be produced regeneratively. There are various ways to produce renewable methanol. One is to capture CO2 from geothermal power generation which is then reacted together with renewable hydrogen (produced via electrolysis) into renewable methanol. Other methods are to convert biogas from fermentation or gasification of sustain- able biomass into bio-methanol as well as producing it from solid waste feedstocks. It is also produced as a by-product of the kraft pulping process in paper production. Methanol can be used in adapted combustion engines or as a hydrogen carrier for fuel cells. Reforming at 300 °C produces H2-rich refor- mate gas. When used with a Proton Exchange Membrane Fuel Cell (PEM FC), a fine purification is necessary. Reforming reduces the overall system efficiency of a FC system. Methanol is toxic when inhaled, but when leaked into water it quickly biodegrades. Due to the liquid property of methanol (it remains liquid up to a temperature of 60 °C at ambient pressure), the advantage of methanol is that it does not require pressurised or cryogenic storage tanks. And with that it also has a relatively high energy density. Due to the corrosiveness, materials for piping and tanks need to be selected carefully and components of engines to be retrofitted have to be considered. Stainless steel or appropriate coat- ings (Zinc) are proven solutions. The release of methanol on-board requires a careful safety assessment, as it is not only toxic, but also a low flash point fuel. In addition, the oxidation of methanol can produce methanal (CH2O, also known as formaldehyde) which is not only toxic but also cancerogenic and able to denaturise proteins. This needs to be considered carefully in the control of combustion processes and potential after-treatment systems.
