Introduction & Uses

Adipic Acid Specification Sheet

ADIPIC ACID (hexanedioic acid; 1,4-butanedicarboxylic acid) is ranked 46th highest volume chemical in World use; and has a a wide range of commercial applications.

The biggest use of Adipic Acid (over 80% of production) is in the manufacture of Nylon and similar man made fibres / filaments.

Other Major Volume uses include:

• Manufacture of Polyurethane foams and elastomers – usually tailor-made for specific industry applications, for example:

1. automotive industry applications – car interior components such as dashboards, steering wheels, door handles and upholstery – exterior components such as bumpers, wheel arches etc.;
2. furniture industry – foam seating / cushions / pads, upholstery etc.;
3. textile industry – fabric coatings, foam quiltings etc.;
4. footwear industry – outer and inner soles, leather look fabrics etc.; and
5. building industry – insulation products etc.

• Preparation of Esters for use as plasticisers and lubricants – identified by names ending in “adipate” ( = a salt of adipic acid ) and used as chemical intermediates across a very wide range of industries. for example :

1. most common : di-octyl adipate (DOA), di- methyl adipate ( DMA ) – used in processing other polymers, solvents, special lubricants, aircraft lubricants, cosmetics, rubber industry etc.
2. others : di-(n-octyl-n-decyl) adipate (DNODA) – low temperature plasticiser, di-isodecyl adipate ( DIDA ) etc,

• Manufacture of water treatment products – eg: flocculants, chlorine purification, domestic cleansers

• Other uses : Adhesives, Food and Pharmaceutical additive ( acidulant ) Baking powders.

“SEV-DON”

The plant at SEVERODONETSK ( “Sev-Don”*) is the largest chemical enterprise in the Ukraine and consists of 4 production groups:

1. ammonia liquid, methanol,formalin and urothropin, argon;mineral fertilizers(urea, ammonium nitrate, ammonium carbonate salts), nitric acid, potassium and sodium nitrate,
2. catalysts for production of ammonia, methanol, acetic acid, adipic acid;
3. organic synthesis salts (cyclohexane, cyclohexanone, adipic acid, nylon 6,6 salts);
4. acetylene, VAM, polyvinyl alcohol, polyvinil acetate dispersion, formalin-carbamid, resin, acetic acid, butyl acetate.

*(“Sev-Don” is a trade mark of Valetime Group )

ADIPIC ACID

Facilities for Adipic Acid use production methods,technology and key equipment from the German company BASF.

Production at “Sev-Don” is based upon contract processing operations with the major supplier of raw material (Benzene) being a Valetime associate.

“Sev-Don” is now the largest independent producer – given that Adipic Acid is principally produced and used by the major international filament (nylon) manufacturers.

Exports to Europe were developed from early in 1997 to meet shortages at the major Western European producers of Adipic Acid. Since that date quality has been enhanced and packaging improved and an international  market is now serviced.

Against this background it should be noted that currently Sev-Don is still supplying Adipic Acid to major Western Producers. Such supplies are not merely for “internal use” to release own production. In some cases the final branded packaging is undertaken at Sev-Don.

The Ukraine has a large and well established chemical industry and production of Adipic Acid is undertaken at 2 locations – ROVNO and SEVERODONETSK.  The Adipic Acid available through Valetime is only from SEVERODONETSK.

Other Valetime products available from “Sev-Don”:

• Acetic Acid
• Adipic Acid
• A G S Acids ( Low DiCarbon Acids )
• Cyclohexanone

Specification

Adipic Acid Specification Sheet

Traditionally Ukrainian production of Adipic Acid has been to Russian (GOST) standard No. 10558-80. This sets out the minimum standard for production.

However, it is recognised that for many end users the colour and related characteristics (chromacitry, iron content etc.) are of vital importance. In fact data taken from recent production at Sev-Don shows in actual results that the product is typically better than the Russian specification assigned to it. Accordingly product sold by Valetime is to an “improved” specification.

Adipic Acid from Valetime is available not from store but directly from production at Sev-Don.

Quality

Quality control of the product utilises Rhodia systems and each batch is subject to testing and certification of analysis ( C of A.) To confirm their confidence in these arrangements Sev-Don will agree to any further independent tests or controls required and provided by end-users.

Furthermore Valetime’s Kiev office has direct contacts at the producer and has sight of every C of A before loading is authorised. Accordingly if required the “purchasing specification” of customers can be used to check each batch. Customers can also be sent a copy of the C of A at this stage – that is some time before actual delivery of their order.
