- RSME rapeseed oil methyl ester
- rapeseed oil methyl ester (RSME) is used as biodiesel. It is already possible that engines with pure biofuel are operated according to the EU directive. However, the addition of up to 2% RSME to normal diesel is likely to be required to comply with the EU directive.
- This RSME consists in the conversion of the natural triglyceride into a methyl ester or ethyl ester.
- the byproduct of this preparation route is crude glycerin.
- biodiesel as rapeseed methyl ester arise 100 kg of free glycerol.
- free glycerol With the increasing amount of biodiesel, the availability of glycerol increases. Since glycerine has a limited market size, which is already covered by previous productions, a disposal problem arises. This circumstance may limit the usual production route for biodiesel, as glycerol can no longer be counted as additional income, which will make this route economically unattractive.
- the manufacturing process should be as environmentally friendly and economical as possible.
- hydrolases especially lipases (EC 3.1.1.3) are already used in industrial processes for lipid cleavage or transesterification.
- lipases EC 3.1.1.3
- the classical chemical method of monoglyceride production proceeds via a base-catalyzed glycerolysis of triglycerides, typically giving a yield of 40-60% monoglyceride relative to the total glycerides. Further enrichment up to> 90% monoglyceride content takes place via physical separation methods such as molecular distillation or crystallization.

- JP03108489 and JP03187385 (Meito Sangyo Co. Ltd.) describe the regioselective hydrolysis of triglycerides with alkaline lipase with the addition of alkaline salts. It is a lipase that is active only under alkaline conditions.
- JP03103499 (Meito Sangyo Co. Ltd.) describes the regioselective alcoholysis of PUFA triglycerides with isobutanol in the presence of an alkaline lipase.

Due to the e-emulsifying character of the monoglycerides formed, possibly formed fatty acids, free glycerol and small amounts of water in the product are dissolved in a single phase. Traces of water are better bound and no longer disturb the combustion process.
- the educated Monoglycerides increase the lubricating properties.
- the components in the composition according to the invention can, in their mixture, cause residual glycerine to be better burned in the combustion process.
- alcohol can be completely or partially removed from the composition prepared according to the invention, for example by distillation, before admixing it with the diesel.

- Diesel fuels are obtained from gas oil by cracking or from tars recovered from the carbonization of lignite or coal. Diesel fuels are flame retardant mixtures of liquid hydrocarbons which are used as fuels for constant pressure or burner engines (diesel engines) and consist predominantly of paraffins with admixtures of olefins, naphthenes and aromatic hydrocarbons. Their composition is inconsistent and depends especially on the manufacturing method. Typical products have a density between 0.83 and 0.88 g / cm3, a boiling point between 170 and 360 ° C and flash points between 70 and 100 0 C.
- Another object of the invention is the use of the inventive composition comprising alkyl esters having an alkyl radical containing 1 to 8 carbon atoms, and partial glycerides having a glycerol content of free glycerol of not more than 2 wt .-% based on the total amount of the composition or the preferred embodiment of this composition or compositions obtainable by the processes according to the invention as biofuel.

- a biofuel is produced and made available, which includes the benefits of raw materials from renewable sources.
- Advantage of the bio-fuel according to the invention is in addition to the production by-products also the introduction of additional oxygen in the combustion path, which reduces exhaust gases.
- the additional lubricating action of the partial glycerides leads to the need for the use of lubricity improvers is unnecessary.
- the first production process saves energy because it proceeds purely enzymatically and without much purification of the final product.
- a further object of the invention is the use of the inventive composition containing alkyl esters having an alkyl radical containing 1 to 8 carbon atoms, and partial glycerides and in particular methyl and / or ethyl esters, monoglycerides and methanol and / or ethanol which has a glycerol content of at most 2% by weight based on the total amount of the composition or the preferred embodiments of this composition or compositions obtainable by the processes according to the invention as an additive in fuel compositions and preferably in amounts of from 0.5 to 10% by weight, in particular from 1 to 5% by weight.
- Particularly preferred is the use of the composition of the invention as an additive for improving the lubricity of fuel compositions.
- glyceride mixtures with a high content of monoglyceride show good lubricating properties. It has thus been possible to show that the monoglycerides prepared by the process according to the invention can also be used as fuel additives in diesel fuel and show good lubricating properties.
- the enzymatic process according to the invention makes it possible to use the regiospecific fatty acid composition of the naturally occurring oils.
- the monoglyceride fraction mainly contains the fatty acid composition found in the 2-position of the oils.
- the higher unsaturated fatty acids are preferentially bound in the 2-position. This allows e.g. starting from sunflower or thistle oil monoglycerides with a high content of linoleic acid. These monoglycerides have a lowered solidification point, which is particularly important for the use of monoglycerides as a diesel additive. Based on palm oil, e.g. to obtain a monoglyceride with a high content of oleic acid.
