Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
October 1992 - January 1993
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
Principles of method if other than guideline:
The boiling point determination was attempted by a capillary tube method using a Buchi 530 melting/boiling point apparatus to provide heating.
GLP compliance:
yes
Type of method:
other: capillary tube method
Boiling pt.:
> 280 °C
Atm. press.:
101.3 kPa

The boiling point was not determinable, since it exceeded the maximum temperature (280 °C) of the apparatus.

Conclusions:
The boiling point of 1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined at >280 °C by 1013 hPa.
Executive summary:

The boiling point of 1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined according at OECD guideline 103 " Boiling point / Boiling range" and EU method A.2 "Boiling temperature". The capillary tube method using a Buchi 530 melting/boiling point apparatus showed an value of >280 °C by 1013 hPa.

Description of key information
