ABSTRACT:
A vapor of diethylzinc or dimethylzinc is reacted with water vapor to form very small particles of depleted zinc oxide which are entrained in the gas flow. In accordance with one version of the method, a spray nozzle is used to mix liquid diethylzinc with dry nitrogen to prevent combustion. The nozzle sprays the diluted diethylzinc into a chamber heated up to its boiling point of 118.degree. C. to completely vaporize the diethylzinc. The diluted diethylzinc gas is then reacted with water vapor to form a fume of very small zinc oxide particles entrained in ethane gas without combustion. A similar process can be used to convert dimethylzinc into depleted zinc oxide powder. In accordance with another version of the process, an inert gas stream is saturated with diethylzinc or dimethylzinc vapor by passing a dry inert gas through a vessel containing liquid diethylzinc or dimethylzinc. A second inert gas stream is saturated with water vapor in a similar manner. These two gas streams will chemically react to form a fume of very small zinc oxide particles.
