Abstract
Abstract A process for stabilizing mixtures of gasoline and methanol containing at least 30% by volume of methanol is disclosed wherein a primary, linear or branched chain monohydroxylated aliphatic saturated alcohol containing from 8 to 15 carbon atoms or a mixture of such alcohols, is added to the gasoline/methanol mixture. The stabilized mixtures described herein are useful as a fuel for automobiles.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
A process for stabilizing mixtures of gasoline and methanol containing 30% to 60% by volume of methanol and 70% to 40% by volume of gasoline which comprises adding to these mixtures a primary, branched or linear chain, monohydroxylated aliphatic saturated alcohol containing 8 to 15 carbon atoms, or a mixture of such alcohols, the quantity of said alcohol or mixture of alcohols added to the mixture of gasoline and methanol being less than or equal to 10% by volume in relation to the volume of the gasoline/methanol mixture.
Claim 2
Dependent Claim
88 words
A process for stabilizing mixtures of gasoline and methanol containing 30% to 60% by volume of methanol and 70% to 40% by volume of gasoline which comprises adding to these mixtures a primary, branched or linear chain, monohydroxylated aliphatic saturated alcohol containing 8 to 15 carbon atoms, or a mixture of such alcohols, the quantity of said alcohol or mixture of alcohols added to the mixture of gasoline and methanol being less than or equal to 10% by volume in relation to the volume of the gasoline/methanol mixture.
Claim 3
Dependent Claim
81 words
The process according to claim 1, wherein the alcohol or mixture of alcohols added is selected from the groups consisting of 1-octanol, 1-nonanol, 2-ethyl-1-hexanol, branched-chain alcohols of the formula C 7 H 15 CH 2 OH and their mixtures, branched-chain alcohols of the formula C 8 H 17 CH 2 OH and their mixtures, mixtures of primary monohydroxylated aliphatic saturated alcohols having 9 to 11 carbon atoms, and mixtures of primary monohydroxylated aliphatic saturated alcohols having 13 to 15 carbon atoms.
Claim 4
Dependent Claim
38 words
The process according to claim 1 wherein a mixture of alcohols is added which is a mixture of primary monohydroxylated aliphatic saturated alcohols having 9 or 11 carbon atoms, in which mixture the linear chain alcohols are predominant.
Claim 5
Dependent Claim
58 words
A composition comprising 30 to 60 parts by volume of methanol, 70 to 40 parts by volume of gasoline, 0 to 0.5 part by volume of water and at most 10 parts by volume of a primary, linear or branched chain, monohydroxylated aliphatic saturated alcohol, containing from 8 to 15 carbon atoms or a mixture of such alcohols.
Claim 6
Dependent Claim
58 words
A composition comprising 30 to 60 parts by volume of methanol, 70 to 40 parts by volume of gasoline, 0 to 0.5 part by volume of water and at most 10 parts by volume of a primary, linear or branched chain, monohydroxylated aliphatic saturated alcohol, containing from 8 to 15 carbon atoms or a mixture of such alcohols.
Claim 7
Dependent Claim
36 words
The composition according to claim 4, in which the mixture of alcohols is a mixture of primary monohydroxylated aliphatic saturated alcohols containing 9 or 11 carbon atoms, in which mixture the linear chain alcohols are predominant.
