This page provides further information on the applications for authorisation or review reports, which have undergone public consultation. The applications for authorisation are in the opinion development phase until the final opinions of the Committees for Risk Assessment and Socio-economic Analysis have been adopted and sent to the European Commission. The European Commission's decision-making process can be followed through the comitology register, where further information is published about the REACH Committee's past and upcoming meetings.

Use name
Use as an extraction solvent in caprolactam production
Broad information on use applied for (conditions of use and function)
Trichloroethylene (TCE) is used as an extraction solvent in the industrial manufacture of caprolactam from cyclohexanone (i.e. via Beckmann rearrangement). Caprolactam is used as a precursor in the manufacture of polymers.

Conditions of use: TCE is used in a continuous, closed-loop, solvent extraction process to recover caprolactam from a two-phase aqueous system comprised of caprolactam in water (containing 70-72% caprolactam, termed ?raw lactam?) and ammonium sulphate (containing 0.8% caprolactam). Caprolactam is subsequently back-extracted into demineralised water and the TCE is recycled and partially regenerated by distillation. Ammonium sulphate is a by-product of the process. Approximately 100 tonnes per year of TCE are used to replace solvent loss from the system and consumption is gradually declining. The closed loop system contains a total of 250 tonnes of TCE.

Technical function: Key functional requirements for the solvent used for caprolactam extraction are identified as follows:
  • Extraction efficiency in the range of 90 – 95%
  • Loading capacity for caprolactam in the range of 19 – 20% at 20 °C
  • Viscosity lower than or equal to 0.55 mPa.s at 30 °C
  • Density higher than 1.24 kg/l and different to that caprolactam by at least 0.2 kg/l
  • Water solubility lower or equal to 1.1 g/l at 20 °C
  • Boiling point in the range of 50 – 100 °C to ensure the ready recyclability of the solvent
  • Absence of flammability classification
  • Compatibility with existing feedstock (cyclohexanone oxime in oleum)
  • Compatibility with the continued generation of ammonium sulphate by-product

Annual tonnage used: 100 tonnes
Review period requested: 12 years
