Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2016-10-24 until 2017-05-03

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

comparable to guideline study

Qualifier:

equivalent or similar to guideline

Guideline:

other: internal method 2011-0343801-92D (DTA/DSC)

Version / remarks:

corresponds to OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No: 113 “Screening Test for Thermal Stability and Stability in Air ”

Principles of method if other than guideline:

Samples of the test item and of a reference material are subjected to the same controlled temperature programme. The difference in energy input necessary to maintain identical temperatures between the test item and the reference material is recorded. When the test item undergoes a phase transition, the corresponding change of enthalpy gives an endothermic (melting) or exothermic (freezing) deviation from the base line of the temperature and heat flow record.

GLP compliance:

yes

Type of method:

differential thermal analysis

Specific details on test material used for the study:

Date of receipt: 2014-01-15
Expiry date: 2017-03-07

Remarks on result:

not determinable

Remarks:

No boiling point was detectable up to decomposition of the test item.

At room temperature the substance is solid.

Several exothermic phases in different temperature ranges were observed.

A first exothermic phase was detected between approx. 85 °C and 125 °C which could indicate a chemical change and / or decomposition of the test item. Between approx. 180 °C and 270 °C and approx. 295 °C and 350 °C two further exothermic effects were observed.

After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item.

Conclusions:

No boiling point was detectable up to decomposition of the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate.

Executive summary:

Boiling point of the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate was determined via Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC). After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item. No boiling point was detectable up to decomposition of the test item.

Description of key information

No boiling point was detectable up to decomposition of the test item.

Additional information

After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item.
