Remarks on result:
other: based on log P = 5.8666 - (3036.8/T)

Reference reports vapor pressure equation log P = 5.8666 - (3036.8/T).

Conclusions:
The reported vp is 0.003 mm Hg @ 90 oC based on log P = 5.8666 - (3036.8/T) (90 oC chosen to be consistent with AkzoNobel data ranging from 90 oC - 140 oC).
Executive summary:

The reported vp is 0.003 mm Hg @ 90 oC based on log P = 5.8666 - (3036.8/T) (90 oC chosen to be consistent with AkzoNobel data ranging from 90 oC - 140 oC).
