Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Materials and methods
- Principles of method if other than guideline:
- The acidic, basic, and neutral fractions of a tar obtained from a condensate of a high-Btu coal gasification pilot plant were analysed by capillary column gas chromatography and gas chromatography / mass spectroscopy. Studies were performed to characterize the interactions between basic and neutral fraction components of the tar and aqueous solutions containing Fe3+.
- GLP compliance:
- no

- Molecular formula:
- C7H9N
- IUPAC Name:
- 4-methylaniline

Constituent 1
Results and discussion
Any other information on results incl. tables
Methylaniline was transported from the organic to the aqueous solution of about 13-27% when exposed to 20 ppm Fe3+, whereas 78-84% decrease of methylaniline concentration was observed in the organic phase when exposed to 200 ppm Fe3+for 18 hours.
Methylaniline (toluidine) was identified in the basic fraction of the low-temperature reactor tar at following concentrations:
=> 14.8 mg/g at 30.0 min. retention time
=> 19.6 mg/g at 30.6 min. retention time, and
=> 46.3 mg/g at 31.2 min. retention time.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
