What Is Lindlar's Catalyst. Web a lindlar catalyst is referred to as a heterogeneous catalyst that comprises palladium deposited on calcium carbonate or barium sulphate which is after that. Web lindlar catalyst, which is a mixture of pd, caco 3, and lead salts, is the catalyst of choice in catalytic hydrogenation of alkynes to give alkenes.
