Dr Noam Greenspoon, Chemada's Deputy General Manager for R&D, gave a dissertation on "Ionic Liquids: Design, Preparation and Application to Green Chemistry" (large file)at the 70th meeting of the Israel Chemical Society, which was held in Tel Aviv in February 2005.

Chemada has recently received accreditation to the Israeli equivalent of OSHAS 18001. This is in continuation of Chemada's Quality and Environmental Policy and our commitment to environmental conservation and health and safety of our employees and the surrounding communities.

Chemada has joined the Responsible Care (R) Program in Israel. This is a continuation of Chemada's Environmental and Safety policy, Community awareness and a fore runner to the SI/OHSAS 18001 (Occupational Health and Safety) accreditation.

A general presentation on Ionic Liquids and Chemada's capabilities in the field of Ionic Liquids are shown in this Powerpoint© show (1.2 MB. For more information please contact Dr. Noam Greenspoon.

A novel class of ionic liquids have been developed by Chemada in collaboration with the Ben-Gurion University in Beer Sheva. Details on these new benzylimidazolium salts have been presented during the conference on Green Solvents for Catalysis organized by DECHEMA in October 2002, at Bruchsal Germany. The work was awarded first prize by the organizing committee. More information on these materials may be received from Dr. Noam Greenspoon.

Traditionally, chemistry and especially organic chemistry is studied in molecular solvents (e.g. water, alcohols, toluene, dichloromethane etc.). Ionic liquids are salts that are molten at room temperatures and are attracting a lot of interest recently as a “green” substitute for molecular solvents. They are very good solvents for many materials, organic and inorganic, have no detectable vapor pressure, are thermally stable and are liquids over broad range of temperatures.

Numerous applications have been demonstrated in the last 5 years for ionic liquids including uses as a medium for electrochemistry, for organic reactions and catalysis, for extractions and separations.

Chemada, in collaboration with the group of Prof. Geresh at Ben Gurion University in Beer Sheva has initiated a research program aiming at developing processes for the production of known ionic liquid on a large scale. In addition several novel ionic liquids with improved properties are under development.

Research scale quantities of the following ionic liquids are available upon request.

1-Butyl-3-methyl imidazolium hexafluorophosphate.
1-Butyl-3-methyl imidazolium tetrafluoroborate.
