The reasoning is simple. Superior Performance Emerox® Azelaic Acid equals or outperforms sebacic acid in virtually all derivative forms. E m e r y ' s azelaic a c i d is a 9-carbon, straight chain, satu rated, dibasic acid. Sebacic acid has 10 carbon atoms. The net result is you're paying approximately ]§f^ more per pound for that extra atom you don't even need. A n d , on a 40,000-pound carload, that's a 14

premium of ^12,0gg. Equivalent in nylon One example of azelaic acid performance is the use of 6/9 nylons (based on Emerox 1144) for applications formerly re quiring 6/10 nylons. The 6/9 nylons are equivalent to 6/10 in these areas: flexibility and toughness; tensile strength; elongation and flexural modu lus properties; and, resistance to hydrolysis and moisture pickup. Moreover, 6/9 nylons exhibit superior low-tempera ture properties and color. Equivalent in polyester adhesives Polyester adhesives prepared
from azelaic acid are equiva lent to sebacic acid derived adhesives in both heat and hydrolytic stability. A n d , by finishing the azelate polyester at a slightly higher tempera ture the same degree of crystallinity can be achieved. Better in plasticizers The same cost/performance relationship applies to other derivatives of Emerox Azelaic Acid and sebacic acid. For ex ample, di-2-ethylhexyl azelate (DOZ) and di-octyl sebacate (DOS) are both excellent lowtemperature plasticizers and give equivalent overall per-
sebacic acid in everything but price. formance. The difference is the azelate is priced DO 301 less per pound. 25-35$ Improves food films Comparing food film plasticizers is another case in point. Di-n-hexyl azelate ( D N H Z ) and di-butyl sebacate (DBS) perform well in this applica tion—although D N H Z gives better overall performance. Again, the azelate costs 00 00^ less per pound. 25-35* Quality/Economy When you consider the quality and performance similarities between azelaic and sebacic
