Definitions
- the invention relates to diesel fuel compositions containing oxygenated compounds consisting of glycerol acetal carbonates.
- US Patent 4891049 discloses a diesel fuel comprising an additive based on alkyl carbonate.
- R 1 and R 2 are each a hydrogen atom, a methyl, ethyl or propyl radical and R 3 is a methyl or ethyl radical.
- R 1 and R 2 are each a hydrogen atom, a methyl, ethyl or propyl radical and R 3 is a methyl or ethyl radical.
- the sum of the number of carbon atoms of R1, R2 and R3 is at least 2.
- This reaction is generally carried out in a basic medium with a catalyst selected for example from hydroxides, carbonates, alkoxides and hydrides of alkali or alkaline earth metals or other metals.
- a catalyst selected for example from hydroxides, carbonates, alkoxides and hydrides of alkali or alkaline earth metals or other metals.
- This reaction can also be carried out by condensation of a urethane of general formula R 3 -CO-NH 2 on the free hydroxyl function of the glycerol acetals with release of ammonia, the urethane R 3 -CO-NH 2 which can itself be obtained easily by condensation of the alcohol R3-OH with urea.
- the glycerol acetals are themselves prepared most often by reaction, generally in an acid medium of an aldehyde or a ketone on glycerol or by transacetalization reaction. These reactions, applied to an R-OH alcohol, are represented by the diagrams below: 2 R-OH + R'CHO ⁇ (RO) 2CH-R '+ H2O (3) 2 R-OH + (R "O) 2CH-R ' ⁇ (RO) 2CH-R' + 2R" OH (4)
- the products used in the invention may consist of one or more compounds corresponding to the general formulas (1) and (2).
- the diesel fuel in question may be of petroleum origin or a mixture of alkyl esters derived from vegetable oils.
- the diesel fuel compositions of the invention may contain glycerol acetals in various proportions.
- the glycerol acetal carbonate or each of the glycerol acetal carbonates will be introduced into the diesel fuel at a concentration such that it is soluble in said diesel fuel.
- proportions of 1 to 40% by volume, usually 1 to 20% by volume, are used.
- diesel fuel compositions of the invention are generally free of Group IIA metal compounds of the Periodic Table of Elements.
- Example 1 the synthesis of glycerol acetal carbonates is described.
- Example 3 describes tests for evaluating the performance of gas oil compositions closing the glycerol acetal carbonates prepared in Examples 1 and 2.
- Example 1 is repeated replacing n-butyraldehyde with an equimolar amount of acetone.
- the product of the reaction corresponds mainly to the following formula:
- the particulate emissions measured with these fuels will be compared with those obtained with diesel alone.
- the tests were conducted on a diesel vehicle equipped with a direct injection engine.
- cycle MVEG-11s Euro 2000 The test results, expressed in gram of particles per kilometer, are presented on each phase of the cycle and on the complete cycle.
