04 · Handling and storage

Storing and handling Tin tetrachloride

Storage conditions

Store in a cool, dry, well-ventilated location. Outside or detached storage is preferred.

Source: Hazardous Substances Data Bank (HSDB)

Incompatible materials

STANNIC CHLORIDE REACTS WITH TURPENTINE, PRODUCING HEAT AND SOMETIMES FLAME.

Source: Hazardous Substances Data Bank (HSDB)

Reactivity

STANNIC CHLORIDE readily hydrolyzes to form hydrochloric acid in aqueous solution or moist air. Combination of stannic chloride with turpentine is strongly exothermic, and may lead to ignition [Mellor, 1941, Vol. 7, 446].
