Conclusions:
The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 ''Boiling Point'' (July 1995).
The boiling point of REACTION MASS OF 2,2,6-TRIMETHYL-1-OXASPIRO[2.5]OCT-5-ENE AND 4-ISOPROPYLIDENE-1-METHYLCYCLOHEXENE was determined by Differential Scanning Calorimetry (DSC) and should be stated at (197.9 - 213.1 +/- 0.2)°C or (471.0 - 486.3 +/- 0.2)K at 1013.25 hPa.
Executive summary:

The purpose of the study was to determine the boiling point of substance REACTION MASS OF 2,2,6-TRIMETHYL-1-OXASPIRO[2.5]OCT-5-ENE AND 4-ISOPROPYLIDENE-1-METHYLCYCLOHEXENE.

The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 “Boiling Point” (July 1995).

The boiling point of REACTION MASS OF 2,2,6-TRIMETHYL-1-OXASPIRO[2.5]OCT-5-ENE AND 4-ISOPROPYLIDENE-1-METHYLCYCLOHEXENE was determined by Differential Scanning Calorimetry (DSC) and should be stated as (197.9 - 213.1 +/- 0.2)°C or (471.0 - 486.3 +/- 0.2)K at 1013.25 hPa.

 

Description of key information

The boiling point of  REACTION MASS OF 2,2,6-TRIMETHYL-1-OXASPIRO[2.5]OCT-5-ENE AND 4-ISOPROPYLIDENE-1-METHYLCYCLOHEXENE is (197.9 – 312.1 +/- 0.2)°C or (471.0 – 486.3 +/- 0.2)K at 1013.25 hPa

Key value for chemical safety assessment

Additional information

The flash point of REACTION MASS OF 2,2,6-TRIMETHYL-1-OXASPIRO[2.5]OCT-5-ENE AND 4-ISOPROPYLIDENE-1-METHYLCYCLOHEXENE

 was determined in a study performed according to the OECD 103 Guideline and the EU A.2 method. The value was considered with a reliability of 2 (reliable with restrictions) because the result is scientifically acceptable but not obtained under GLP and some details were lacking in the report.
