Pour Point of CAS Number 101316-62-5 was <-30°C.

Conclusions:
The pour point of CAS Number 101316-62-5 was < -30°C.
Executive summary:

Information was provided by individual companies in the form of a letter stating the relevant information. The letter was submitted in company’s headed paper and signed by the individual responsible for the area of work. Given that the companies have practical expertise in handling the substance/stream this was deemed to be acceptable information. The pour point of CAS Number 101316-62-5 was < -30°C.

Description of key information

The melting point data for four streams were available. The melting point range was < -30 to 45°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
4.8 °C

Additional information

Melting point values for the streams in this category have been take from proprietary data, certificates of analysis and study reports and are considered reliable and suitable for use for this endpoint. CAS# 94733-07-0: 4°C (BASF, 2007); CAS# 68477-54-3: < -30°C (RÜTGERS 2010a, 2010b, 2010c, 2010d, 2010e, 2010f, 2010g, 2010h); CAS# 101316-62-5: < -30°C (RÜTGERS, 2010b); CAS# 68526-56-7: 35°C – 45°C (Dow Benelux 2010b).

 

The data will be read across to all category members.

 

The mean of the melting point values for the category is 4.8°C and this value has been used to complete the 'key value for chemical safety assessment'.
