THE INVENTION
The invention is drawn to a method for making an emulsion
by contacting a solid which contains at least one of
tetraethyl lead or bromoethane with a solution having an
appropriate hydrophilic lipophilic balance or HLB value, the
solution being present at a sufficient concentration to
emulsify tetraethyl lead and bromoethane. Thereafter the
emulsion is separated from the solid, and recovered.
THE CLAIM
Claim 1 is illustrative of appellants’ invention and is
reproduced below.
1. A method for making an emulsion comprising:
(a) preparing an aqueous surfactant solution,
(b) contacting a solid, which contains at least one of a
tetraalkyllead and a bromoethane with an amount of the
solution that has a hydrophile lipophile balance value and
concentration sufficient to form an emulsion comprising at
least one of a tetraalkyllead and a bromoethane,
