.in Wax Emulsions ϋ . S art, engineering, and witchcraft are the ingredients for good wax emulsion. When Common wealth Color and Chemical brought in some wax emulsions for tests, our spirits waned a little because as every good chemist knows, wax emulsions are fickle. However, the art was good, and our Rapisonic was soundly engi neered. The immediate test results were very gratifying. A short while later our happiness was complete when we added Common wealth Color and Chemical to our ever growing list of friends and users. The tremendous disruptive forces of cavi tation developed right inside the liquid by the Rapisonic gave them results at a speed which had to be seen to be believed. Thus another happy marriage of chem istry and engineering a n d . . . a little more grist to our mill. • in Âdlicsivcs 1 111-— 1 ultrasonics puts stickem in adhesives, too.

INDUSTRIAL A N D ENGINEERING CHEMISTRY
Our work in the promising—but relatively undeveloped —field of pyrrolidine chemistry has led to the development of an interesting series of nitrogen heterocyclics. This group of unusual, difficult-to-obtain synthetic pyrrolidine derivatives (with boiling points ranging from 80.5° C. to 201° C.) includes: N-Dimethylpyrrolidinium Chloride N-Butylene Pyrrolidine N-Methyl Pyrrolidine Pyrrolidine Carbonate N-Hydroxy Ethyl Pyrrolidine N-Hexyl Pyrrolidine A series of 3, 5 disubstituted pyridine derivatives are also available. Typical compounds in this series are: 3, 5 Dimethyl Pyridine 3, 5 Diphenyl Pyridine 3, 5 Dibutyl Pyridine. Some of these new compounds are being used in extraordinary and profitable ways. While SECURITY (ah, this atomic agel) prevents us from disclosing the exact who and how of these uses, we would like to tell you what we know about the performance characteristics of the nitrogen heterocyclics. If you have more than a casual interest in these specialized chemicals, we suggest your investigation begin by writing for our latest technical bulletins . . . and for sample quantities. If your development is somewhat further along, we're available for consultation.
