Justification for type of information:

As the substance is thermal not stable the vapour pressure must be conducted at temperatures from 55 to 60 °C.
During this measurement it is expected that first water and phosphoric acid as the smallest molecules will evaporate. Their molecular mass than will be used for the calculation of the vapour pressure. The expected value of this calculation will be very close to the vapour pressure of water and phosphoric acid.
In addition, the substance contains more than 50 % inorganic substances with a melting point greater than 300 °C, where the measurement of the vapour pressure for the single substances was waived. The both organic components have melting points between 200 °C and 300 °C, where vapour pressure measurement also could be waived. Calculation for Amylopectin s not possible because as a polymer it is outside the applicability range of the calculation method. The calculated value for D-Glucose, 4-O-.beta.-D-galactopyranosyl-, monohydrate, using the Modified Grain Method (EPI Suite v4.11) is 1.1*10-13 Pa at 25 °C.
Considering all this, determining the vapor pressure of this substance is not technically feasible and scientifically not justified.
