Description

General description

Les solvants de qualité EMSURE conviennent à un large éventail d'applications de laboratoire classiques et sont fréquemment utilisés dans des applications de laboratoire réglementées et hautement exigeantes. Les produits EMSURE proposent les spécifications les plus complètes et les meilleures au monde. Nous déclarons notre gamme EMSURE conforme aux spécifications ACS, au chapitre "Réactifs" de la pharmacopée européenne (Réact. (Ph. Eur.) et aux normes ISO.

Application

Cyclohexane can be used as a solvent in the synthesis of:

• POSS-HCCP Freestanding Films (Polyhedral Oligomeric Silsesquioxane and Hexachlorocyclotriphosphazene) and Thin-Film Composite (TFC) membranes.
• Cyclomatrix polyphosphazene films via nonaqueous interfacial polymerization.
• Thin-film composite membranes such as MDHB-HCCP (m-dihydroxybenzene and hexachlorocyclotriphosphazene) and THB-HCCP (1,3,5-trihydroxybenzene and hexachlorocyclotriphosphazene).
