Preparation of Lindlar’s catalyst

Preparation of Lindlar’s catalyst

To a stirred suspension of 50 g of pure, precipitated calcium carbonate in 400 ml of distilled water are added solution of 4.2 g of anhydrous palladium chloride dissolved in 45 ml of water and 4 ml of concentrated hydrochloric acid and the stirring continued for 5 minutes at room temperature and then 10 minutes at 80° C. The hot suspension is then shaken with hydrogen until no further uptake can be observed and the impregnated calcium carbonate filtered off and well washed with distilled water. It is then suspended in 500 ml of distilled water by vigorous stirring and a solution of 5 g of lead acetate dissolved in 100 ml of distilled water are added; stirring is continued for 10 minutes at 20° C and then 40 minutes in a boiling water-bath. The catalyst is filtered off, washed well with distilled water and dried in vacuo at 40-45° C.
