Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

Administrative data

Endpoint:
flash point of flammable liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Chemical Name Hexadecyl dihydrogen phosphate
Other Name 1-Hexadecanol, 1-(dihydrogen phosphate)
Commercial Name Cola Fax CPE
Physical State Solid
CAS # 3539-43-3
EC # 222-581-1
Manufacturer Colonial Chemical, Inc.
Batch #/Lot # 57826G17
Received on January 2, 2018
Tested on February 5, 2018 and February 6, 2018
Key result
Melting / freezing pt.:
>= 55 - <= 77.6 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
no
Sublimation:
no
Remarks on result:
other: A wide temperature range was noted on melting. This will be due to the fact that this substance is a multiconstituent substance with a number of components

Summary of DSC Melting Point Results for Hexadecyl Hydrogen Phosphate

Replicate #              Onset of Melt,°K              End of Melt, °K

1                                329.5 (56.4°C)              351.7 (78.5°C)

2                                326.6 (53.5°C)              349.8 (76.6°C)

Average                     328.1 (55.0°C)              350.7 (77.6°C)

Conclusions:
The sample does not display a freezing point on cooling. It does exhibit a melt with an average onset of 55.0°C and a completion of 77.6°C.
DSC traces show one diffuse and one sharp peak over this temperature range, which is consistent for a multiconstituent substance.
