Introduction

 

Five assays were performed during the test. For the boiling point, two assays complied with the accuracy criterion. Only these assays are presented below.

 

Assay No. 3

 

Gas used         Nitrogen

Ventilation        Yes

Atmospheric pressure   97.8 kPa

Crucible used   Aluminium, 120 µL, with pierced lid

Mass of test item         8.30 mg

Program                      Phase 1: Isotherm at about 25 °C for 5 min

                                   Heating phase from 25 °C to 600 °C at 10 °C/min

 

The observed boiling point of this assay was 63.2 °C. The boiling point corrected to the atmospheric pressure was 64.2 °C.

Exothermic peaks were observed from about 150 °C to 200 °C and from about 220 °C to 275 °C.

 

Assay No. 5

 

Gas used         Nitrogen

Ventilation        Yes

Atmospheric pressure   98.6 kPa

Crucible used   Aluminium, 120 µL, with pierced lid

Mass of test item         8.71 mg

Program                      Phase 1: Isotherm at about 25 °C for 5 min

                                   Heating phase from 25 °C to 300 °C at 10 °C/min

 

 

The observed boiling point of this assay was 63.0 °C. The boiling point corrected to the atmospheric pressure was 63.7 °C.

Exothermic peaks were observed from about 160 °C to 200 °C and from about 220 °C to 275 °C.

Conclusions:
The mean corrected boiling point of the test item was 64.0 °C ± 0.5 °C.
Executive summary:

The boiling point of Phosphonium, tetrakis(hydroxymethyl) -, sulphate (2:1), reaction products with 1-tetradecanamine and urea has been determined according to EC A.2 method and OECD test guideline 103 in compliance with GLP.

A differential scanning calorimetry method (DSC) was used for the determination of the boiling point. The boiling point was 64.0 °C ± 0.5°C at 13013 hPa.

Description of key information

The boiling point was determined to be 64.0 °C ± 0.5°C at 1013.25 hPa

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
64 °C

Additional information

An experimental study scored as Klimisch 1, was selected as a key study. It was performed in compliance with GLP according to EC A.2. test method and OECD 103 test guideline.
