esters of Emery acids make excellent JET
engine lubricants
Compounders of jet engine lubricants are increasingly employing EMOLEIN® Lubricant Esters as the base fluids of their lubricants. Di-iso-octyl azelate and dioctyl azelate are two of the best base fluids yet discovered. They possess superior resistance to oxidation and corrosion at 350-400°F. Their volatility is low, their flash point high, and their lubricity excellent. A.S.T.M. slopes are low; their fluidity at low temperatures is the best available. Pelargonic esters are also excellent lubricants. Blended with azelates, they provide high level performance at lower cost. Currently under test is EMERY 3383-D High Tem-

A new improved grade of azelaic acid (n-nonanedioic acid) is now available specifically for the production of polymers in the medium molecular weight class. It's called EMEROX® 1133 Azelaic Acid. Residual monobasic acids have been removed to make EMEROX 1133 especially suited for polymerization reactions where the unusual properties

perature Lubricant Ester. It is a base stock for compounding lubricants to meet requirements above the "Type I" fluids now in use. EMOLEIN Lubricant Esters are also used as base fluids in specialty greases requiring long-time performance or high performance at very low temperatures. If you are compounding lubricants to meet either military or commercial requirements, or if you have a specialty lubricant application, it will pay you to look at the EMOLEIN Lubricant Esters. We'll be happy to send you technical bulletins describing the products available, and to provide samples for your evaluation.

R l \ l I S H E S for substantial saving
If you use tung oil, you are well aware of its current high price. EMPOL® Dimer Acids have the ability to beef up less expensive drying acids and oils to do a satisfactory job in many varnishes at a much lower cost. Kettle times are nearly always shortened, which means more dollars saved. As one example, a 10-gallon varnish containing 15% EMPOL 1022 Dimer Acid and 85% soya oil (plus 12 lbs. glycerine per

100 lbs. dimer acid) is equivalent to one containing 20% tung oil and 80% soya oil. Virtually indistinguishable, in fact.
New low temperature flexibility is now available for food wraps and coatings with new PLASTOLEIN® 9051 DNHZ low temperature plasticizer. Recently issued Section 121.2528 of the FDA covers the use of di-n-hexyl azelate as a plasticizer for resins that contact food. Thus, the advantages of the azelate plasticizers—outstanding low temperature flexibility, excellent film properties and good all-around performance—can now be obtained for PVC and other resins used in food packaging film and coatings.
You can save by substituting dimer acid for high price tung oil. If you'll tell us the varnish you are making and the oils you're using, we'll send a sample of the proper grade of dimer acid for you to evaluate, as well as a copy of our technical bulletin on dimer acid.
PLASTOLEIN 9051 DNHZ (formerly Emery 869-D) may be used in compliance with this regulation. It is especially effective because of the high clarity of its films, its prevention of brittleness at freezer temperatures and its great compatibility and efficiency. Use of PLASTOLEIN 9051 DNHZ offers significant cost reduction over other tow temperature plasticizers currently used. Although PLASTOLEIN 9051 DNHZ was developed primarily for use in polyvinyl chloride and vinyl chloride copolymers, the unique 9-carbon structure of azelaic acid on which it is based also makes it advantageous for polyolefins and other resins and coatings.
twitchell® oil helps control
POWDER DUST
H provided by this C 9 dibasic acid are sought. Such properties include increased flexibility, better low temperature performance, and lower melting points. Write for a sample and a copy of Technical Bulletin No. 426. Emery is continuing research efforts to develop new grades of azelaic with higher degrees of purity designed for high molecular weight polymers.
TWITCHELL 7420 Oil is an effective dust inhibitor with powdered dyestuffs. It may be that 7420 (or another of our surface-active chemicals) will solve similar dusting problems of other powders. If you have such a problem, you might give it a try. We'll be glad to send you a sample of TWITCHELL 7420, if you'll mail in the coupon.
Send for evaluation samples and technical literature.

Partial amide-esters of various aliphatic dicarboxylic acids are being used as adhesives on certain non-tacky tapes for pipe insulation. The non-tacky characteristics of the tape enable it to be wound on a roll without difficulty. As it is unwound prior to use, heating activates the thermoplastic adhesive, enabling it to be stuck into position. As it cools, it sets firmly into place. Azelaic acid has the faculty for keeping the tapes tacky over a longer period of time, providing more time to apply the tape after it is heated. This particular application is the subject of several patents—see, for example, U.S. 2,708,650—but it does show a facet of azelaic's utility in adhesives. If you'd like to try a sample of EMEROX® 1110 Azelaic Acid in your own adhesive, check off the coupon and send it in.
