Durable Water Repellents from Fatty Amides " A r m i d " is t h e Armour t r a d e - n a m e given to the general class of long chain fatty amides derived from fatty acids. These high molecular weight amides are highmelting, wax-like materials. T h e com-» mercially pure amides are water-insoluble a n d neutral. One a m i d e in this series. Armid H T . has superior properties for water repellency applications when compared with paraffin a n d natural waxes. T h e excellent water repellent properties of Armid H T derivatives are due primarily to the combination of the amide grouping with a long, saturated straight chain. Durability of the water repellent effect results from the relative insolubility of thé derivatives under dry-cleaning operating conditions, and from their high-melting points and poor emulsification characteristics with the soaps and d e t e r g e n t s used in laundering. Armid H T is composed of 2 5 ' , hexadeeane amide, 70' , octadecane amide a n d f>', octadecene amide, is off-white in color and has a melting point of a p p r o x i m a t e l y 98° C. In contrast with t h e chemical inertness of the hydrocarbons, Armid H T is reactive chemically. A d v a n t a g e has been t a k e n of its reactivity with formaldehyde in particular to prepare thermally unstable q u a t e r n a r y ammonium salts. T h e s e are applied to fabrics from aqueous solution and decomposed under heat to leave an insoluble, durable water repellent

Lard Oil Lubricants Lard oil possesses the p r o p e r t y of "oiliness" so essential in the lubrication field. In addition, lard oils are readily saponified when t r e a t e d with alkalies a n d possess non-drying qualities. W h e r e a high grade lubricant is required as in d r a w i n g copper and brass tubing, Extra W i n t e r Strained Lard Oil is recom mended. I t s low free fatty acid c o n t e n t makes it ideally suited as a base for such products. E x t r a Winter Strained Lard Oil is only one in a complete range of lard oils offered to the lubrication held by the A r m o u r Chemical Division.

Reactivity with formaldehyde also permits compounding of stearamide or its derivatives w i t h thermosetting resins to produce durable water repellent effects. Many of these thermally unstable compounds, however, are covered b y p a t e n t s and those patents should be consulted. Armid H T is packaged in flake form in 100 lb. multi-wall paper b a g s .

Low-Temperature Solvent Crystallized Oleic Acid Another new product has been added to A r m o u r ' s line of fatty acids. Already the m a n u f a c t u r e r of the most complete line of high-purity distilled fatty acids t h a t can be found anywhere, t h e Armour Chemical Division now offers low-temp e r a t u r e solvent crystallized oleic acid. This exclusive process offers users of oleic acid a product t h a t has a d v a n t a g e s not found in ordinary distilled or pressed p r o d u c t s . T h e extremely low temperat u r e s employed g u a r a n t e e a substantially lower s a t u r a t e d acid content t h a n conventional types of oleic acid. In addition, solvent crystallized oleic acids are esterfree materials since the solvent used is not reactive with fatty acids. This new product is characterized by bland odor a n d has excellent h e a t stability. Armour's low-titer White Oleic Acid m e e t s U. S. P h a r m a c o p e i a specifications a n d is recommended for those uses t h a t require a light color a s well as a low titer. For applications t h a t require a low titer b u t not a very light color, low-titer Distilled Red Oil is recommended.

To help research chemists, t h e A r m o u r Chemical Division continually prepares in formative l i t e r a t u r e on chemicals derived from fats. T h e two technical bulletins de scribed below a r e available free of charge. For research chemists interested in fatty a m i n e s (organic bases or alkalies made from fatty acids), A r m o u r has pre pared a detailed 24-page bulletin entitled, " T h e C h e m i s t r y of F a t t y A m i n e s . " " T h e C h e m i s t r y of F a t t y Acids" is t h e title of a n o t h e r technical bulletin offered by t h e A r m o u r Chemical Division.
