Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Justification for type of information:
- As the target substance is hydrolytically unstable with hydrolysis half-life less than 30 minutes at 30°C, testing is not feasible. According to hydrolysis test results, the hydrolysis products have been identified to be 2,2',2''-Nitrilotriethanol (triethanolamine) and zirconium dioxide. The physical, toxicological and ecotoxicological properties of the organic parts have been well-investigated. Read-across approach from hydrolysis products are used for assess the target substance.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Boiling pt.:
- ca. 335.4 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- The boilng point of the target substance is 335.4°C read-across from its hydrolysis product.
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Triethanolamine is the main hydrolysis prodcut of the target substance. Properties of the hydrolysis substance is used for read-across.
- Guideline:
- other: not specified.
- GLP compliance:
- not specified
- Type of method:
- other: not specified.
- Key result
- Boiling pt.:
- ca. 335.4 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- The boiling point of triethanolamine (2,2',2''-nitrilotriethanol) is 335.4°C according to literature.
- Executive summary:
Read-across data from hydrolysis product.

Description of key information
Boiling point of triethanolamine is 138.0 °C according to literature.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 335.4 °C
Additional information
According to hydrolysis test results, the hydrolysis rate was estimated to be less than 30 minutes. The hydrolysis products had been identified to be 2,2',2''-Nitrilotriethanol
(triethanolamine) and titanium dioxide. The boiling point of triethanolamine was chosen for CSA.
