Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Principles of method if other than guideline:
in house method JA-701 based on pycnometer method
GLP compliance:
no
Other quality assurance:

In-house data reports density as 1.14 g/cm3 @ 10 oC, 1.123 g/cm3 @ 25 oC, 1.108 g/cm3 @ 40 oC, 1.096 g/cm3 @ 50 oC (interpolated 1.1288 g/cm3 @ 20 oC)
Executive summary:

In-house data reports density as 1.14 g/cm3 @ 10 oC, 1.123 g/cm3 @ 25 oC, 1.108 g/cm3 @ 40 oC, 1.096 g/cm3 @ 50 oC (interpolated 1.1288 g/cm3 @ 20 oC)

Endpoint:

Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The method is well described, the purity is at least 95%, no information on impurities. The purity is derived from a sharp melting point.
Qualifier:
no guideline followed
Principles of method if other than guideline:
pycnometer method used
GLP compliance:
no

Specific density is 1.1218. The reference liquid is not given.

Specific gravity usually means relative density with respect to water.

Conclusions:
The relative density of dichloroisobutylaluminium is 1.1218 at 20°C.
Executive summary:

In this old publication the purity is derived from a sharp melting point. No further analysis were done. So the purity is questionable.

No impurities were determined.

The reference liquid is not mentioned.

Specific gravity usually means relative density with respect to water.

The relative density of dichloroisobutylaluminium is 1.1218 at 20°C.

Description of key information

The relative density of dichloroisobutylaluminium is 1.125 @ 20 oC, the average of Knap (1.1218) and AkzoNobel in-house data (1.1288). Since the substance is a transported intermediate, no further testing was done.

Key value for chemical safety assessment

Relative density at 20C:
1.125

Additional information

Average is taken from two sources, Knap and AkzoNobel.

Knap:The relative density of dichloroisobutylaluminium is 1.1218 at 20 °C.

AkzoNobel:The interpolated density of dichloroisobutylaluminium is 1.1288 at 20 oC
