Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

no guideline available

Principles of method if other than guideline:

An attempt was made to determine the boiling point of the sample by the Siwoloboff method in a heated metal block using photocell detection consistent with OECD Guidelines for The Testing of Chemicals, 103, July 27 1995. However, the instrument was not suitable for analysis due to the high viscosity of the sample. As a result, a deviation from the OECD 103 guideline was necessary and the boiling point test was obtained by performing thermogravimetric analysis (TGA) on the sample.

An attempt was made to determine the boiling point of the sample by the Siwoloboff method in a heated metal block using photocell detection consistent with OECD Guidelines for The Testing of Chemicals, 103, July 27 1995. However, the instrument was not suitable for analysis due to the high viscosity of the sample. As a result, a deviation from the OECD 103 guideline was necessary and the boiling point test was obtained by performing thermogravimetric analysis (TGA) on the sample.

Using thermogravimetric analysis, the sample is placed in a DSC hermetic pan with a laser drilled pinhole in the lid. When the sample starts to boil, the vapor pressure in the pan increases causing a weight loss through the pinhole in the lid. The onset of the derivative of this weight loss is taken to be the boiling point of the sample.

The boiling point was measured using a TA Instruments 2950 TGA and hermetic pin-hole DSC pans. Approximately 4 mg samples were analyzed. The sample was too viscous to sample at room temperature, so it was heated to 80°C to remove an aliquot. TGA analysis was performed by heating the sample from room temperature to 500°C at 5°C/min. Two replicate trials were performed.

Conclusions:

Boiling point of 4,4’-Isopropylidenediphenyl, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with cyclohex-1,2-ylenediamine was determined to be 395.7 C using thermogravimetric analysis.
