An apparatus for vaporizing volatile liquids comprises a packed column, a gas inlet port (for introducing a hot entrainer gas), a feed tube (for introducing a volatile liquid), a feed distributor comprising a base plate equipped with orifices (through which the liquid flows downward into the packed column) and risers (through which the formed gaseous mixture of entrainer gas and vaporized liquid flows upward), and a gas outlet port. This apparatus can be used to vaporize volatile liquids, preferably volatile tin compounds, optionally in admixture with volatile silicon compounds, wherein steam is used as the entrainer gas.
