The present invention relates to elastomer compositions comprising adducts between compounds of formula (I) preferably derived from natural sources such as mucic, pyromucic, glucaric, glycaric, galactaric, muconic acid and/or linear derivatives thereof containing ester or amide groups and/or cyclic derivatives thereof with heteroatoms in the ring, such as oxygen or nitrogen, and carbon allotropes in which the carbon is sphybridized, such as for example carbon nanotubes, graphene or nanographites, carbon black.

Elastomer compositions comprising an adduct between an SP2 hybridized carbon allotrope and a dicarboxylic acid derivative

The present invention relates to a vulcanizable elastomeric composition comprising a secondary accelerator that may be used in combination with sulphenamide alone, completely avoiding the use of a guanidine. Moreover, said accelerator promotes dispersion of the silica in the compound and migrates with difficulty in the elastomeric composition itself. The invention also relates to the use of a vulcanization accelerator for said elastomeric composition, to the associated vulcanization process and to a tyre comprising same.

Elastomeric composition and vulcanization accelerator used therein

The present invention relates to a process for the synthesis of molecules that have a pyrrole ring bonded to a diol. In particular, the invention relates to the synthesis of molecules that have the pyrrole ring and a diol derived from serinol by means of a process that does not demand the use of solvents or chemical catalysts. The process consists of a first reaction phase that takes place without any solvents and/or organic diluents, giving rise to an intermediate compound, and a second phase in which the intermediate compound is converted into the required compound by heating the reaction mixture to a temperature ranging from 100&#xb0; to 200&#xb0; C. for an interval in the range of 1 to 500 minutes, or by adding a carbon allotrope or its derivatives.

Process for the synthesis of 2-(2,5-dimethyl-1H-pyrrol-1-yl)-1,3-propanediol and its substituted derivatives

An adduct consists of derivatives of serinol pyrrole and of carbon allotropes in which the carbon is sphybridized, such as carbon nanotubes, graphene or nano-graphites or carbon black, in order to improve the chemical-physical properties of the allotropes increasing above all their dispersibility and stability in liquid media and in polymer matrices, and a process for preparation of the adduct.

Adducts between carbon allotropes and serinol derivatives

The present invention relates to a process for the preparation of iodinated anilines; in particular, it relates to a process including the direct iodination, with suitably activated iodine, of 3,5-disubstituted anilines to the corresponding 3,5-disubstituted-2,4,6-triiodoanilines, which are useful intermediates for the synthesis of x-ray contrast media, and to the preparation of the contrast media themselves. 

Process for the iodination of aromatic compounds

The present invention relates to a process for the preparation of iodinated phenols; in particular; it relates to a process including the direct iodination, with suitably activated iodine, of 3,5-disubstituted phenol compounds to the corresponding 3,5-disubstituted-2,4,6-triiodophenols, which are useful intermediates for the synthesis of x-ray contrast media, and to the preparation of the contrast media themselves.
