The addition of a phase transfer catalyst can increase the reaction rate and efficiency. This is converted from a benzyl halide to a benzyl fluoride or a carboxylic acid halide to a carboxylic acid fluoride. 
	Naf (sodium fluoride) is less efficient and the solubility of commonly used solvents is poor. If the disadvantages listed previously are not important, then Naf (sodium fluoride) is less hygroscopic and less expensive. In general, laboratory synthesis uses kf, and when enlarged into a plant program, Naf (sodium fluoride) will be replaced if possible.
