Lot# UN3261
Decomposition:
yes
Decomp. temp.:
169 °C

The sample was placed into a melting point capillary tube and heated in the metal block in the instrument. During the course of heating, sample decomposition was observed, which was indicated by its color change from white to a brownish color. The heating parameters used were 165 - 185°C at 0.5°C/minute. The onset of a slow color change was observed at about 169°C, indicating decomposition.

Conclusions:
Melting point of 2-Hydroxyethyliminodi(acetic acid) was measured using photocel method following OECD 102 guidance requirements. It is not possible to determine melting point as substance is decomposing before reaching boiling point. Decomposition starts at approximately 169 C.
Executive summary:

Melting point of 2-Hydroxyethyliminodi(acetic acid) was measured using photocel method following OECD 102 guidance requirements. It is not possible to determine melting point as substance is decomposing before reaching boiling point. Decomposition starts at approximately 169 C.
