| titleOfInvention | METHOD OF OBTAINING PETROL ETHERS |
| abstract | A subject of the invention is a method for preparing mixed esters of the general formula I, wherein Ar is an alicyclic, aromatic or one or more heteroatoms heterocyclic group which may be substituted by one or more Salkoxy, methylenedioxy, C 1-6 alkyl group, halogen, Haloalkyl or nitro group and / or condensed with a benzene ring, R and R are independently of each other hydrogen, C1-6alkyl, Haloalkyl, C1-6alkenyl, phenyl, substituted phenyl, Cycloalkyl, R2 represents a C1-6alkyl group, which could substituted with one or more C1-6alkyl, C1-6alkenyl, C1-6alkynyl, Haloalkyl or halogen atom; or a C1-6 alkyloxy-C1-6 alkyloxy group, characterized in that the reaction is carried out between compounds of the general formula II, where X is a hydroxyl, halogen or sulfoester leaving group, and 1-3 molar equivalents of an alcohol of the general formula III, where the substituent has the meanings indicated above, in the presence of an acid, Lewis acid, metal oxide or metal carbonate; the resulting ester of general formula I is isolated, if necessary, stabilized by the addition of a base and / or antioxidant and, if necessary, an excess of alcohol is regenerated. |
