World production of methanol is growing rapidly and its uses are expanding as a result of environmental legislation requiring the use of cleaner fuels. A new equation of state has been developed which represents the available reliable data to within their experimental accuracy. In particular the equation is able to represent the rapid increase in the heat capacity of the gas near to saturation which results from the association of the molecules due to hydrogen bonding. This book contains the tables of the equilibrium properties for both the liquid and the gas, complemented by a critical assessment of all the data and comparisons with the equation of state
