Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2005

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP not known information from published handbook data limitations in design and/or reporting but otherwse adequate for assessment

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The NIOSH Pocket Guide to Chemical Hazards is intended as a source of general industrial hygiene information for workers, employers, and occupational health professionals. The Pocket Guide presents key information and data from the US Department of Health and Human Services and as such is a reliable governmental source of information

Description of key information

The boiling point of high purity DCPD is 172.2°C. The boiling point of commercial DCPD (>80%) is 80-190°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

172.2 °C

Additional information

The Pocket Guide presents key information and data from the US Department of Health and Human Services and as such is a reliable governmental source of information and is considered a suitable key study source for this endpoint (NIOSH 2005). This is supported by a boiling point of between 170°C and 172°C from the WHO ICSC (2005). The test substance decomposes at this temperature range. No information on the primary source of the data or the methods used is available. However, this information is taken from a reliable peer reviewed database and so can be considered reliable and suitable for use for this endpoint.

The boiling point of commercial DCPD was taken from proprietary data (DOW 2016). There is no information on the GLP status of the study or the methods used but the results are taken from company specific datasheets and are considered to be suitable for use for this endpoint.
