Additional information

The vapour pressure values for streams in this category have been taken from proprietary data, study reports and certificates of analysis.

CAS# 68477-54-3: 380 Pa at 19.9°C, 7900 Pa at 34.5°C, 1230 Pa at 48.9°C (Sabic, 1989a); <2000 Pa (<0.02 Bar) at 100°C (Sabic, 2009b) ; 4100 Pa at 25°C (EMBSI, 2003a); 200 - 550 Pa at ca 20°C (RÜTGERS 2010a, 2010b, 2010c, 2010d, 2010e, 2010f, 2010g, 2010h).

CAS# 68526-56-7: 1033 Pa at 20°C (LOA Consortium, 2009).

CAS# 94733-07-0: 910 Pa at 20°C, 1119 Pa at 25°C, 2948 Pa at 50°C (BASF, 2007a).

CAS# 101316-62-5: 2758 Pa (0.4 PSI) at 20°C and 400 Pa (Rutgers 2009f/2010b).
