There are no values given for pressure but assumed to be measured at normal pressure (1013 hPa). No information is given on decomposition/sublimation temperature.
Preliminary Testing
The thermal stability measured with DSC in the closed aluminium crucible showed an endothermic effect (boiling) in the temperature range 280 – 330 °C at 10 °C/min. No exothermal decomposition showed in the measurement range.

The boiling point was not corrected to P = 101.3 kPa because the calculation of Hvof reaction mix can introduce not acceptable errors.
Description of key information
268 °C at ca. 1013 hPa
Key value for chemical safety assessment
Additional information
The boiling point of the substance "Reaction mixture of glycerol-1,3-di(acetate), glycerol acetate and triacetin"
(EC 905-964-4) was determined according to OECD Guideline 103. The other determination of the boiling point (266.5 °C) with ASTM E 537-07 according to EPA OPPTS 830.7220 (1995), OECD-Guideline No. 103 (1995) and Method A.2 (EC 440/2008) was supporting.
