then ETHYLENE CARBONATE PROPYLENE CARBONATE Both of these carbonates are outstanding in their solvent properties for many classes of organic compounds which are difficult to dissolve. They are also miscible with many common solvents, including water. These properties suggest applications in selective or extraction solvents. Carbamates are formed easily with ammonia and aliphatic amines, leading to many applications in resins, agricultural chemicals, plasticizers and other products. When the use of ethylene oxide or propylene oxide is inconvenient, alkoxylations can be effected with the corresponding carbonates. Propylene carbonate has a ΙΟΛ# viscosity at low temperatures and a high boiling point (242°C. ), suggesting applications in hydraulic fluids and similar functional liquids. Jefferson ethylene carbonate and propylene carbonate are available commercially in drum quantities, and samples will be sent on request. Write for the Jefferson technical bulletins on these carbonates to Jefferson Chemical Company, Inc., 1121 Walker Avenue, Houston 2, Texas.
