General description

Lanthanum(III)chloride heptahydrate is a mild, inexpensive, and moisture-stable heterogeneouscatalyst widely used in several organic transformations.

Application

Lanthanum(III) chloride heptahydrate can be used as an efficient catalyst for :
  • Solvent-free preparation of substituted alkenes via Knoevenagel condensation.
  • One-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones.
It can be used as a precursor to synthesize La/V co-doped TiO2 nanoparticles through the sol-gel method. La co-doped TiO2 nanopowder show enhanced photocatalytic activity.

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
