Abstract: This invention describes the preparation of fatty acid esters of glycerol formal either by a triglyceride transesterification process or, alternatively, by an esterification process of fatty acids previously obtained from the hydrolysis of triglycerides (fat splitting), with glycerol formal in the presence of an acid or basic catalyst. Also the invention describes the use of these fatty acid esters of glycerol formal prepared by said process as biofuel. In an embodiment, such biofuel is used in the preparation of other biofuels by its mixture with a product selected from a group formed by: glycerol formal, biodiesel, petrol-derived diesel, and mixtures thereof. The biofuels thus obtained are characterized to allow the complete incorporation of the glycerol obtained in the current biodiesel production process in a biodiesel fuel.

Abstract: The invention relates to degreasing compositions comprising at least one dialkyl amide of formula (I), R1CO—NR2R3, in which R1CO represents a linear or branched, saturated or unsaturated, aliphatic or aromatic, optionally hydroxysubstituted acyl group having 2 to 56 carbon atoms, and R2 and R3 independently represent alkyl groups having 1 to 6 carbon atoms. The compositions are useful for degreasing hard surfaces, particularly metal surfaces.

Abstract: A preparation process of aromatic ketones by a Friedel-Crafts acylation reaction in an ionic liquid of formula (I), in the absence of any other catalyst and/or solvent. In formula (I), [Q]+ is selected from substituted-imidazolium cations, substituted-pyridinium cations, ammonium cations, and phosponium cations. It allows to carry out Friedel-Crafts acylations with good yields and high selectivity in para position of the Friedel-Crafts aromatic substrate without using chlorine-containing solvents and conventional Friedel-Crafts catalysts. It is industrially useful because provides a “Green Chemistry” technology for carrying out Friedel-Crafts acylations of general aplicability.
