EC number: 272-712-1 | CAS number: 68909-77-3 The residuum from the reaction of diethylene glycol and ammonia. It consists predominantly of morpholine-based derivatives such as [(aminoethoxy)ethyl]morpholine, [(hydroxyethoxy)ethyl]morpholine, 3-morpholinone, and 4,4'-(oxydi-2,1-ethanediyl)bis[morpholine].

Description of key information
The pour point of the test substance was determined to be less than -20 ± 3°C (<253 ± 3 K), using the pour point method BS 2000: Part 15 (equivalent to ISO 3016), designed to be compatible with EC test method A.1, under GLP conditions (Butler and White, 2010).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
The pour point is determined to be below -20 °C; the bounded value of - 20 °C can be used for the CSA.
