Abstract
A novel process is disclosed for preparing hydrocarbon mixtures from methanol or trimethyl phosphate. The process comprises heating the methanol or trimethyl phosphate with phosphorus pentoxide, polyphosphoric acid or a species of polyphosphoric acid intermediate between the two reagents at a temperature of circa. 185.degree. C. to 300.degree. C. The hydrocarbon mixtures obtained are useful fuel and lubricant compositions.

A process for preparing a mixture of hydrocarbons, which comprises;
- heating a mixture comprising in a molar ratio of from about 1:1 to 1:2.2, phosphorus pentoxide and trimethyl phosphate to a temperature within the range of from about 185.degree. C. to about 300.degree. C.
A process for preparing a mixture of hydrocarbons, which comprises;
- heating a mixture comprising in a molar ratio of from about 1:1 to 1:2.2, phosphorus pentoxide and a compound selected from the group consisting of methanol, trimethyl phosphate and mixtures thereof, to a temperature within the range of from about 190.degree. C. to 220.degree. C.
A process for preparing a mixture of hydrocarbons, which comprises;
