Naphthalenesulfonic acids, branched and linear Bu derivs., sodium salts

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

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

Cross-reference 1

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

Study period:

2013

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:

yes

Type of method:

differential scanning calorimetry

Melting / freezing pt.:

490 K

Remarks on result:

other: in air and nitrogen atmospheric

Sample	Analysis	Starting Temperature	Final Temperature	Temperature programme	Atmosphere	Weight (kg)	Melting point
Test substance	A	273 K	490K	0.167 k/min	Air	2.58 *10-6	> 490
	B					2.36 *10-6	> 490
	C				Nitrogen	2.39 *10-6	> 490
	D					2.75 *10-6	> 490

Conclusions:

The melting point resulted in all tests higher than 490K.

Executive summary:

The melting point of the substance was determined in means of DSC according to the OECD Guideline 102.

The melting point resulted in all tests higher than 490K (216.85 °C).
