These are less common than ethanol-gasoline blends but do find application in countries including China where the composition range available is M15 to M80 (15%…

In the tables of properties of methanol and ethanol the vapour pressure at 38°C has been given as this is the temperature at which RVP…

As methanol is a pure chemical compound its physical properties are precise. For example, there is no need to talk of the Reid Vapour Pressure…

The two alcohols of most importance in fuel technology are the two most structurally simple: methanol and ethanol. Both are good fuels for spark ignition…

When it was first proposed to construct ‘dust-free roads’ by using tar instead of the inorganic materials used previously there was concern that the vapour…

Clearly solid and liquid will often be in co-existence and the viscosity is a factor in any application. This can be determined from the classical…

The processing of tars remains an important industry in countries including the US and Japan. Tar distillate is considerably less of a ‘rag bag’ of…

The term tar generally means the liquid decomposition product of any organic substance, for example wood or peat. It is with coal tars specifically that…

When a coal decomposes (‘carbonises’) there are three classes of product: solid, liquid and gaseous. The solid we refer to as coke or as char.…

Constituents of petroleum jelly are C25+. Being not a single organic compound but containing many such compounds, petroleum jelly does not have a melting point…
