SiGNa Chemistry: Reactions

Classic Method

Typical hydrogenation reactions result in the addition of hydrogen (H₂) to unsaturated organic compounds in the presence of a metal catalyst. These hydrogenations are limited to specific equipment and expensive precious metal catalysts or difficult reaction conditions with cheaper catalyst alternatives.

Phenanthrene Hydrogenation

Problems

Requires catalysts, either expensive precious metal or less-active catalysts
Conditions utilize long conversion times and high temperatures
Handling of flammable high-pressure hydrogen gas
Safety and economic issues due to special equipment

SiGNa's Method

The SiGNa hydrogenation method does not require expensive catalysts or high pressure hydrogen to complete the conversion due to its electron-donating mechanism. SiGNa's materials and method perform hydrogenations in a smooth solution process at room temperature and pressure utilizing simple sources of hydrogen (water, alcohol, ammonium phosphate, etc.).
