A new and convenient method has been developed for the large scale preparation of (2-hydroxyethyl)trimethylammonium theophyllinate. 1 The synthesis of several (2-hydroxyalkyl)trimethylammonium theophyllinates was accomplished by the addition of trimethylamine to various epoxyalkanes and then reacting the resulting intermediate with theophylline or 8-substituted theophylline derivatives. Various properties of these compounds are described.

A modified photomicrography procedure has been developed to speed the size-frequency method of analyzing emulsions. This method employs a film strip and rule simultaneously projected. Classification of 1,000 oil globules into the proper size intervals can be done in about one-half of the time formerly required. The Minisonic homogenizer was investigated for ( a ) the effect of long insonation periods on emulsions and ( b ) various methods of manufacturing the emulsion. No coagulation of emulsions occurred when exposed to ultrasonic waves for thirty minutes.
