General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

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).
