Applications

Zinc perchlorate hexahydrate, efficiently catalyses the esterification between nearly equimolar amounts of carboxylic acids and alcoholsZinc perchlorate hexahydrate [Zn (ClO4) 2· 6H2O] was found to be a highly efficient catalyst for acylation of electron deficient phenols, sterically hindered alcohols and electron deficient and sterically hindered amines. Zinc (II) perchlorate hexahydrate has been found to be a new and efficient catalyst for conjugate addition of thiols to α, β-unsaturated ketones under solvent-free conditions at room temperature.

Notes

Hygroscopic. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong reducing agents, flammable substances, organic materials, metal powders. Desiccate at room temperature. Keep away from combustible material.
