Administrative data
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Under COLUMN 2 “SPECIFIC RULES FOR ADAPTATION FROM COLUMN 1” in the REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 18 December 2006, it states the study does not need to be conducted if: "the melting point is above 300 degree C" As shown in Harlan Laboratory report Melting Temperature (D04336): Decomposition of Acid Yellow RN 2903 started at about 323 °C before melting occurred. Decomposition of Acid Yellow RN 2903 started at about 323 °C before melting occurred. The estimation of the vapor pressure of Acid Yellow RN 2903 was based on the EEC directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.4 “Vapour Pressure”, EEC Publication No. L383, December 1992 and the OECD Guideline No. 104, “Vapour Pressure”, adopted July 27, 1995. Using the boiling point and the Modified Watson Correlation, the vapour pressure of Acid Yellow RN 2903 can be estimated to be 1.16 x 10-25 Pa at 25 °C based on the free acid form of the main component.

Any other information on results incl. tables
The boiling point of Acid Yellow RN 2903 was calculated for the free acid form of the main component to be approximately 772°C.
The boiling point of the salt form is supposably above 772°C.
Using the boiling point and theModified Watson Correlation, the vapour pressure of Acid Yellow RN 2903can beestimated to be
1.16 x 10-25Pa at 25 °C
based on the free acid form of the main component.

- Conclusions:
- Using the boiling point and the Modified Watson Correlation, the vapour pressure of Acid Yellow RN 2903 can be estimated to be 1.16 x 10-25 Pa at 25 °C based on the free acid form of the main component.
- Executive summary:
Using the boiling point and the Modified Watson Correlation, the vapour pressure of Acid Yellow RN 2903 can be estimated to be
1.16 x 10-25Pa at 25 °C
