Specific details on test material used for the study:

Sponsor batch: E01133-065
Purity: 100 %
Arrival date: 6 March 2017
Re-test date: 31 July 2019
Storage conditions: Refrigerated (2 to 8°C) under nitrogen. The test substance was supplied in a translucent HDPE container and has been stored in this container. The test substance was stored in a fridge, in the dark when not in use.

Key result

Boiling pt.:

ca. 288 °C

Decomposition:

yes

Decomp. temp.:

> 288 °C

Remarks on result:

other: Various endothermic and exothermic artefacts observed from 124°C (test 1) and a major endothermic effect, characteristic of boiling, observed with peak temp 288°C (mean of 288.8 and 287.5°C), followed by signs of decomposition.

Various endothermic and exothermic artefacts were observed from 124°C (test 1) and a major endothermic effect, characteristic of boiling, was observed with a peak temperature of 288°C (mean of 288.8 and 287.5°C), followed by signs of decomposition. The thermograms for tests 1 and 2 are shown in the illustrated Figure 23 and Figure 24 respectively.

A red-brown liquid, similar in colour to the original material remained in the crucible after testing.

Conclusions:

Boiling at peak 288°C followed by decomposition

Executive summary:

In a study, according to OECD 103, the boiling point of neodecanoic acid, iron salt has been characterised. Various endothermic and exothermic artefacts were observed from 124°C (test 1) and a major endothermic effect, characteristic of boiling, was observed with a peak temperature of 288°C (mean of 288.8 and 287.5°C), followed by signs of decomposition.

Conclusions:

The boiling range for neodecanoic acid has been determined to be between 243 and 253°C at 1013 hPa.

Executive summary:

In a study, according to ASTM D1078, the boiling point of neodecanoic acid has been characterised. The boiling range for neodecanoic acid has been determined to be between 243 and 253°C at 1013 hPa.

This information is used in a read-across approach in the assessment of the target substance. For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.

Description of key information

In a study, according to OECD 103, the boiling point of neodecanoic acid, iron salt has been characterised. Various endothermic and exothermic artefacts were observed from 124°C (test 1) and a major endothermic effect, characteristic of boiling, was observed with a peak temperature of 288°C (mean of 288.8 and 287.5°C), followed by signs of decomposition. A red-brown liquid, similar in colour to the original material remained in the crucible after testing.

As a supporting approach, read-across has been made to neodecanoic acid (EC No. 248 -093 -9; CAS No. 26896 -20 -8). Since the determined range between 243°C and 253°C is in the same range as that of neodecanoic acid, iron salt, the read-across approach to the structural analogue can be considered as justified.

Key value for chemical safety assessment
