component of the present invention is an emulsifying agent which acts as a catalyst the emulsifying agent is present in an effective catalytic amount usually at least about 0 01 or more percent by weight of the tertiary halide of formula ii and advantageously at least about 0 1 or more percent by weight preferably the emulsifying agent is present between about 0 1 percent and 5 percent by weight of the tertiary halide and even more preferably between about 0 5 to about 2 percent by weight the term 34 effective catalytic amount 34 when used to describe the amount of emulsifier required in the present reaction refers to an amount of emulsifier which when added to the present reaction accelerates the rate of the reaction in comparison to the present reaction conducted in the absence of an emulsifier suitable emulsifying agents are those emulsifying agents or mixtures of emulsifying agents having an hlb hydrophilic lipophilic balance value of 10 or greater and includes anionic nonionic and cationic emulsifiers or surfactants suitable anionic emulsifiers include alkyl aryl sulfonates such as dodecyl benzene sulfonate and alkyl alkoxy sulfates such as lauryl alcohol sulfate suitable nonionic emulsifiers include polyoxyethylene alkyl phenols such as octylphenol ethoxylated with 9 moles of ethylene oxide which is commercially available as triton u00ae x 100 emulsifier and alcohol ethoxylates such as lauryl alcohol plus 10 moles of ethylene oxide which is commercially available under a variety of trade names such as alfonic u00ae renex u00ae 30 series standamul u00ae and siponic u00ae detergents which contain.
