Results

Effusion method – Knudsen Cell
Vapour pressure was measured in the temperature range of 30 to 110 °C. Measurements up to 55 °C are not shown because no evaluable vapour pressure could be detected up to that temperature.

Table 2 – Effusion method data

No.	Temperature [°C]	Vapour pressure [Pa]
2	25	2.61 x10-3
3	30	3.84 x10-3
4	35	5.52 x10-3
5	41	7.69 x10-3
6	46	1.20 x10 -2
7	51	1.76 x10 -2

 

The constants A and B of the Antoine equation (Equation 2) can be derived by regression of the measured vapour pressure data points to:

A = 7.9355

B = - 3143.01

C = 273.15

Vapour pressure were calculated by interpolation and extrapolation of the measured vapour pressures for the temperatures 20, 25 and 50 °C.

Conclusions:

The vapour pressure of Reaction product of 2-Propenoic acid and Oxirane, mono[(C12-16-alkyloxy)methyl] derivs was evaluated in accordance to OECD 104. The vapour pressure was calculated by interpolation and extrapolation of the measured vapour pressures for the temperatures 20, 25 and 50 °C. The vapour pressure was concluded to be 1.6E-5 Pa.

Executive summary:

The vapour pressure of Reaction product of 2-Propenoic acid and Oxirane, mono[(C12-16-alkyloxy)methyl] derivs was evaluated in accordance to OECD 104. The vapour pressure was calculated by interpolation and extrapolation of the measured vapour pressures for the temperatures 20, 25 and 50 °C. The vapour pressure was concluded to be 1.6E-5 Pa.
