Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

< -20 °C
Atm. press.:
ca. 1 atm
Decomposition:
no
Sublimation:
no

The test item was still not frozen after twelve hours of storage in a freezer at - 20°C.


According to Annex VII of REACH, the study does not need to be conducted below a lower limit of - 20°C. Therefore no main study was performed and the determination was terminated.


No melting/freezing point could be detected for REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE in the experimental condition used. 


The melting/freezing point of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE should be stated < -20°C.

Conclusions:
According to guideline OECD 102 and method EU A.1, no melting point of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE was observed from - 20°C.
Executive summary:

The purpose of the study was to determine the Melting/Freezing point of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE.


The determination of the Melting/Freezing point was performed in accordance with Regulation (EC) No 440/2008, method A.1 “Melting/Freezing Temperature” (May 2008) and OECD Guideline No 102 “Melting Point/Melting Range” (July 1995).



In a preliminary study, the test item was still not frozen after twelve hours of storage in a freezer at - 20°C. According to Annex VII of REACH (Regulation (EC) No 1907/2006), the study does not need to be conducted below a lower limit of -20°C. 


Therefore the determination was terminated.


The Melting/Freezing point of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE should be stated as < - 20°C.

Description of key information

According to guideline OECD 102 and method EU A.1, no melting point of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE was observed from - 20°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C
