摘要:
STANNOUS CHLORIDE IS PREPARED IN THE FORM OF THE DIHYDRATED BY REACTING TIN METAL, STANNIC CHLORIDE AND AN AMOUNT OF WATER SUFFFICIENT TO FORM THE DIHYDRATE. THE REACTION IS CONDUCTED AT AN ELEVATED TEMPERATURE, E.G., AT THE BOILING TEMPERATURE OF THE REACTION MIXTURE. ANHYDROUS STANNOUS CHLORIDE MAY BE OBTAINED BY DEHYDRATION OF THE DIHYDRATE, AS BY DRYING IT UNDER REDUCED PRESSURE.
