Centec’s core business is the processing of multi-tonne batches of products, mainly liquids, frequently involving distillation. You can find more about this business in the “Recycling and Recovery” and “Toll Manufacture” sections.

However, Centec also operates a successful Fine Chemical division, producing a range of value added products in batches of 1 – 999 Kg. These include a number of powder products.

We have created a small catalogue of products that exemplify our experience. This document can be downloaded on the About Us page. The products can be found in databases such as ChemACX, DWCP, ChemSpider and ChemExper.

Below we illustrate some of the main product classes that Centec produce –

Liquid Crystal monomers

We manufacture a range of building blocks for Liquid Crystals. A brochure giving further detail can downloaded on the About Us page. Illustrative classes include –

  • Alkoxy substituted benzoic acids (with possible further ring halogenation)
  • Alkoxy substituted phenols (with possible further ring halogenation)
  • Alkoxy substituted anilines (with possible further ring halogenation)
  • Substituted diaryl esters
Metal 2-ethylhexanoates (octoates)
  • Major products are Iron 2-ethylhexanoate (100’s tonnes p.a.), solutions of Sodium 2-ethylhexanoate (10’s tonnes p.a.), and Chromium 2-ethylhexanoate (100’s Kg p.a.)
  • We expect to shortly commercialise Zinc and Bismuth Octoate products. We have in the past produced on various scales Potassium 2-ethylhexanoate, Cobalt 2-ethylhexanoate, Tin 2-ethylhexanoate
  • We would welcome your interest in these products. We would also welcome enquiries around any similar metal 2-EHA salts, such as Calcium, Cerium, Barium, Zirconium or Manganese
  • Such products can be supplied in a variety of solvents at the user’s choice. For example, we have supplied Iron EHA as a 50% solution in white (mineral) spirit, gas oil, or toluene
  • We have manufactured a range of Coumarins, some up to 100 Kg scale
  • Leading examples are the laser dye Coumarin 152 (7-Dimethylamino-4-trifluoromethylcoumarin) and Coumarin 311 (7-Dimethylamino-4-methylcoumarin)
1,3,5-Triaryl Benzenes
  • We currently produce the parent 1,3,5-Triphenylbenzene (high purity)
  • We are seeking to market a series of functionalised analogues
  • Examples are 1,3,5 Tri-(4-bromophenyl)benzene and 1,3,5 Tri-(4-methoxyphenyl)benzene
Squaraine Dyes
  • We recently began manufacture of a Dihydroperimidine squaraine dye
  • Additionally we have a development project targeting the parent Squaric acid
  • We would welcome a discussion around related structures
  • A dye representative of our current project would be CAS 190544-02-6 or CAS 211991-63-8
  • Legacy terms for this product are WDR3 and PSA1345
Speciality Benzophenones
  • We have experience in producing a range of benzophenones, and are most interested in value added or rare structures
Some Specifically Highlighted Products –
  • Ether ditosylates, such as Ethylene glycol ditosylate, Diethylene glycol ditosylate
  • 1,3 Diones such as Benzoyl acetone, 1,3-Di(4-methoxyphenyl)propan-1,3-dione
  • 4-OH TEMPO (high purity) and derivatives such as 4-Benzyloxy TEMPO
