The present invention lies in the field of nitrocellulose nail varnishes and its subject is the use of an arylsulphonylurethane as film forming resin in these varnishes, which makes it possible in particular to avoid the release of formaldehyde, a carcinogenic compound which is formed when an arylsulphonamide-formaldehyde resin is employed. Another subject of the invention is new poly(arylsulphonylurethanes) containing from 2 to 5 arylsulphonylurethane groups and possessing a molecular mass of between 450 and 1500.

Use of an arylsulphonylurethane as film forming resin in nitrocellulose

The present invention relates to a process for the preparation of a glyceryl mononitrate or of a mixture of glyceryl mononitrates, characterized in that it comprises a bioconversion step of nitroglycerine to glyceryl mononitrate(s) by a microorganism chosen from the group consisting of the yeasts, the fungi and protozoa, preferably a bioconversion step by fungi.

Process for the synthesis of glyceryl monomitrates by bioconversion of

The invention relates to a process of selective bioconversion of DINIS into MONIS-5, wherein the DINIS is added to a medium containing at least one microorganism possessing a glutathion transferase or an acellular extract of such a microorganism.

Process of selective bioconversion of isosorbitol dinitrate

The invention relates to the synthesis of isosorbide mononitrates. The process according to the invention consists in reacting a hydrazine derivative with isosorbide dinitrate, in a polar solvent medium. The reaction is preferably carried out at the reflux temperature of the solvent medium, with an excess of the hydrazine derivative. A preferred solvent medium is a mixture of tetrahydrofuran and methanol. The process leads to the preferential formation of isosorbitol-2-mononitrate, which is a coronary vasodilator.
