Recherche de nouveaux solvants éco-compatibles de substitution dans le cadre de REACH

Abstract : Our study is focused on the search of new solvents eco-compatible alternative development in the framework of the European directive REACH. More particularly, the aim of the project is to substitute the toxic solvents such as N-methyl pyrrolidone (NMP), the cresol and phenol used in the industry of the varnishes of enamelling by solvents of lesser toxicity which enable you to synthesize these varnishes in these solvents while maintaining the same properties. For the synthesis of their varnish of enameling which for example is used for the coating of the copper wires, company IVA uses in great quantity NMP (CMR-1B), phenol and cresol (toxic, irritant, corrossive….). During the process of coating, the solvents contained in varnish are flaring. To substitute these solvents, we will in a first time, study the mechanism of polymerization and thus understand the role of solvents involved. Then, we will proceed to the characterization of the polymer constituents the varnish (the poly (esterimide) s and the polyamide-imides) by synthesizing "authentic" which were characterized ideally by infrared analysis. Finally, we will conduct a screening of different solvents "less toxic" in order to achieve the synthesis of polymers in this/these new solvent(s). The solvents used will be either commercial, or synthesized from biomass. When the varnish of enameling non toxic will be obtained in one or several new solvents of lesser toxicity, we will assess their application properties
