Lindlar catalyst ~ Pd 5% or Pd 10%
CAS number: 53092-86-7
Form: powder
Solubility: not soluble in most organic solvents
Lindlar catalyst is a heterogeneous catalyst consisting of palladium deposited on calcium carbonate and treated with various forms of lead. A heterogeneous catalyst is a catalyst that is always in a different phase or state (solid, liquid or gaseous solution) than the reactants.
Application of Lindlar catalyst
Lindlar catalyst is a heterogeneous catalyst that is mainly used for the selective hydrogenation of alkynes to alkenes.
It can also effectively catalyze:
• Selective hydrogenation of triple bonds to cis double bonds
• Monohydrogenation of polyolefins
• Hydrogenation of azides to amines
