REACH – Hawks and Pre-registration.
You will be aware of REACH and its implications for EU chemical manufacturers and importers who will be required to commence pre-registration of products seeking compliance from the summer of this year. You will find a link here to ReFac, the REACH facilitation company set up by a large group of UK small to medium sized chemical companies to help resident EU companies gain compliance for their products and to assist non EU manufacturers in acting as a sole representative for REACH.
We will be contacting our suppliers on the subject of appointing a sole EU representative shortly and keeping our customers informed on Hawks REACH progress.
If you require assistance with future REACH compliance or just have a question then visit www.refac.eu or go to the link on the links page of this site.

Staff Opportunity at Hawks
We are looking to employ a Sales Manager based in Manchester to manage and develop sales initially of Hawks Chemicals product range of halogenated intermediates and bromine compounds but also to increasingly engage in the activities of Hawks Scientific, a new sister company, a web based laboratory chemical supplier.
We are planning to split the activities of the two companies in time but presently are running both in tandem. As a major percentage of our sales are continental a second language, French or German would be an advantage and you would be joining a very capable team. We are looking for some chemical sales experience and the preferred age range would around 30 years.
If you feel that this challenge might interest you then please write to the Managing Director Dan Kaye with your CV or telephone him for more details.

Hawks Chemicals are pleased to announce an extension to their range of phase transfer catalysts:- the Glymes.
Chemistry:
Glymes belong to the most powerful solvents available today. They have high thermal and chemical stability in a broad pH range and, thus, are used in many high temperature reactions. With their all-ether structure they are very similar to crown ethers and are used in many phase transfer catalyzed (PTC) reactions and several extractions as cost effective replacement for crown-ethers. Please download our PTC- brochure which contains many examples for polyglymes as phasetransfer catalysts.
Unlike other organic solvents, polyglycol dimethyl ethers dissolve many inorganic salts. This is due to the fact that the glyme forms a complex with the cation. Glymes are "LINEAR CROWN ETHERS"
Hence, reactions involving salts can be enhanced in glymes solvents because anions are more reactive (less solvated). Typical examples are sodium borohydride (NaBH4) reductions, anionic polymerizations, nucleophilic substitutions, alkylations and deprotonations involving strong bases and many more. Sodium fluoride (NaF) in glymes solvents is used as fluorine source for the production of fluoro polymers like polytetrafluoro ethylene (Teflon).
The complexing ability of Polyglycol DME types is used in many industrial applications like electroplating and electrodeposition of copper (Cu), chromium (Cr), nickel (Ni). Butyl glymes have high solvency for gold salts (AuCl3).
The high thermal stability of glymes makes them useful additives of solder pastes and soldering fluxes or for high temperature depolymerisation reactions.
Glymes mix with water and with hydrocarbons, alcohols, aromatics etc. in any ratio, i.e. basically with all organic solvents.
Butyl Glymes do not mix with water but mix with most organic solvents. This makes them excellent and safe replacements for solvents like THF, diethyl ether, dibutyl ether and dioxane in Grignard reactions and organo metallic reactions in general. See section about butyl diglyme for more informations.
Glycol dimethyl ethers are very stong solvents. They even can dissolve or swell several types of plastics and polymers and they can be used as plasticisers. This is used to modify for example the properties of fibre glass and plastic fibres.
These outstanding solvent properties combined with an excellent toxicological profile make Dipropylene glycol dimethyl ether an alternative to many standard solvents especially in the field of coatings and paints applications. For example, Dipropylene glycol dimethyl ether is used as replacement for NMP (N-methyl pyrrolidone) in many applications. The chemical and physiacl properties of NMP and Dipropylene glycol dimethyl ether are very similar.
There is a common prejudice that glymes can hardly be removed from reaction mixtures. Glymes are as easy to remove as other solvents. Glymes with low molecular weights (Monoglyme, Diglyme, Triglyme and Tetraglyme) can be removed by a simple distillation. In fact, due to the high stability of glymes, the recovery rates are much higher than for other organic solvents. Polyglymes which can not be distilled can be removed by standard separation processes like washing with water, salting out, solvent extraction and many more.

Hawks EMI5 in Powder Coatings
Hawks EMI5 is a new catalyst available for use in hybrid powder coating resins for low temperature applications on sensitive substrates. It can also be used in thermosetting epoxy polyester powder adhesives curing either thermally or by infrared in 160 - 170 seconds offering considerable cost savings over competitive systems. Please ask us for more information or samples.

Hawks Chemical at Chemspec Dusseldorf 22-23rd June 2005
A note for your diary, we are at Chemspec again and will be exhibiting our range of halogenated specialities. Come and see us at our stand E26, Dan Kaye, Reg Warren and Dr Peter Robinson will be waiting for your enquiries. Have a good exhibition and looking forward to seeing you!
Hawks Scientific Going Forward
Our laboratory at Huddersfield where we control, decant and manufacture a small range of labchem specialities is now running. The Hawks Scientific website has been remodelled and the searchable links to our full labchem range are even easier. We are particularly interested in hard to find organic specialities so if its not on our list send us your enquiry via the E-mail link on our home page and we will get back to you, promise. Remember too that if your requirement for labchem quantities was to go to pilot plant levels or more then the worldwide contractors with whom Hawks Chemical have a close relationship will be able take synthesis to commercial lots without delay.

Hawks Chemicals
are pleased to announce that their new facility for contract
manufacture is now operational. Unusual features are an acid-wash fume
cupboard designed for the synthesis of acid chlorides, large scale (up to
20L) glass-ware and G.C. analysis. Please contact us if you are interested
in using these facilities.
August 2002 - Did You See Hawks in Speciality Chemicals?
If you are outside the EU you may not have seen the article by Dr Peter Robinson, Business Development Manager, recently published in Speciality Chemicals magazine.

November 99 - Hawks Noxious Chemical Bottling Facility
Hawks are pleased to announce that their new bottling plant is now operational. It is specifically designed to handle and contain noxious and corrosive chemicals and vapours and will be primarily bottling bromine in the package detailed below. The facility can also handle and decant other noxious chemicals for example, fuming nitric acid.
Hawks are interested in expanding this business and welcome enquiries from either companies interested in outsourcing their decanting business, or companies where development products require specialist bottling. The bottling plant represents an ideal opportunity for companies to off-load their difficult and dangerous bottling requirements.
Please email us with your enquiry
