•ffe CD Shruaea MAGIC MATERIALS OF TOMORROW'S ALCHEMY θ There i s no known limit to t h e usefulness of "CD'* amines in the chemistry o f the future. F o r these virtually magic materials will help . . . in. uncounted ways . . . to shape the Things to Come. Only your research can bring o u t their t o t a l value to the World of Tomorrow. T h a t i s why the A r m o u r Chemical Division invites research men t o explore t h e potentialities of the " C D " amines . . . in terms of today's problems and the dreams of t h e future. Normally there are eleven different primary amines in the " C D " group . . . almost unlimited possibilities for secondary and tertiary amines, a n d quaternary ammonium compounds. Current produc tion is limited t o 5 members of each series, having alkyl chains of 16 a n d 18 carbon atoms, except i n the case o f high-ranking, priority-rated orders. Samples of those " C D " amines which interest you, together with full data on their characteristics, will be sent on request.

1 pound of Octadecyl Amine -will lift 7,000 lbs. of solids in a flotation cell. 1 pound of Octadecyl Amine Acetate will sterilize 5,000 gallons of water. 1 pound of Hexadecyl Amine Acetate will prevent algae growth in 5 t 000 gallons of water. 1 pound of Dodecyl Amine Acetate will reduce the surface tension of 500 gallons of water & 30°C. from 71 to 22 dynes per cm., or 1,200 gallons of water from 71 to 29 dynes per cm. 1 pound of Octadecyl Amine will form an adsorbed, oriented, monomolecular film on 217,600 acres of glass surface.
