New chemicals and applications from Armour
N e w Armour dimethyl alky! tertiary amines now available in purities of 9 2 % ! T h e new Armour series of dimethyl alkyl tertiary amines, in the highest purity ever produced commercially, are now available in truck or car load lots. Here are new tools that should be of interest as starting materials for new products. T h e unusually high purity, versatility and unique properties of these new chemicals should make them extremely useful in a wide variety of applications. We recommend you test them in your operations. Armour dimethyl tertiary amines bear the Armeen® trade-mark. T h e y have the following configuration. CH3
R-N ^=^Z^ZZ ^ CH3 Where R represents either stearyl (Armeen D M 1 8 ) ; cetyl (Armeen D M 1 6 ) ; soya (Armeen D M S ) ; coco (Armeen D M C ) ; or hydrogenated tallow (Armeen D M H T ) . These contain a minimum of 80% tertiary amine. These materials are also available in distilled grades as Armeens D M 1 8 D , D M 1 6 D , D M S D and D M C D . T h e distilled grades contain a minimum of 92% tertiary amine and are lighter in color. T y p i c a l a n a l y s i s : Armour tertiary amines are made to narrow, exact specifications t o insure uniformity in process ing. The following is a typical analysis:
Ethyl Ether, Mineral Oil, VM&P Naphtha, Ethyl Acetate. Armour tertiary amines have a higher degree of solubility in petroleum products t h a n corresponding primary amines. K n o w n A p p l i c a t i o n s : Armour tertiary amines are find ing profitable use in the following applications: Lubricating oil a d d i t i v e s Activators o f t h i a z o l e a n d t h i u r a m in r u b b e r p r o d u c t i o n Catalysts i n i s o c y a n a t e f o a m s I n t e r m e d i a t e s in q u a t e r n a r y c o m p o u n d s f o r : Algaecides

I n a typical reaction t o form quaternary compounds, benzyl chloride is reacted on a mole-for-mole basis with an Armour tertiary amine in a steam bath for six hoars. Yields are above 90% of theoretical for each of the tertiaxy amines. Armour based quaternaries show outstanding ger micidal properties. The following is the reaction with allcyl and aromatic halides to form quaternary a m m o n i u m salts: -CH3 - f R'CL
