Abstract

A metal such as tin which it is difficult to prepare from its salt by- reduction in a liquid crystal system may more rea'dily be obtained if the reduction is carried out in the presence of a compound of a second metal, such as copper, where the compound of the second metal is more readily reduced by the reducing agent such as sodium hypophosphite than is the salt of the first-mentioned metal.
