Key value for chemical safety assessment

Boiling point at 101 325 Pa:
503 K

Additional information

Temperature dependent vapor pressures for dipropylene glycol n-butyl ether were measured from 10 to 500 mmHg using the dynamic twin ebulliometer technique using diphenyl oxide as the reference substance. The experimental data were correlated with the Antoine equation. The normal boiling point of dipropylene glycol n-butyl ether is determined to be 230 °C at 760 mmHg.
