Description of key information

An experimental boiling point of 324 deg C has been determined for the chemical subject to REACH registration.   Boiling point data are also available for three read-across chemicals. These chemicals are included in the Glycol Esters Category submitted by the American Chemistry Council for the U.S. Environmental Protection Agency as a contribution to the U.S. EPA High Production Volume Chemical Program. All members of this category have similar molecular structure and functional groups. The functional groups in common are aliphatic ester groups and glycol ether groups. The glycol ether groups, joined together in one to four units, are end-capped with aliphatic acids via ester groups. Three of the category members exhibit boiling points =>300⁰C, and the fourth decomposes at ca 250⁰C without boiling. Therefore the boiling points of the three read-across chemicals and the chemical subject to this registration are consistent in having high boiling/decomposition points. The individual values for the read-across category members, as well as the chemical subject to this registration are given in the individual melting point study records in this file.

The MPBPWIN module (v1.43) of the U.S. EPA EpiSuite program (Copyright 2000 -2012) was used to calculate a boiling point for the subject chemical. The value obtained bu this method was 324 ⁰C and is consistent with the values for other similar read-across chemicals.
