Thephase diagram of tolueneis shown below the table. Chemical, physical and thermal properties of toluene : Values are given for liquid at 25oC /77oF / 298 K and 1 bara, if not other phase, temperature or pressure given. For full table with Imperial Units -rotate the screen!
Vapor pressures, and molar volumes, of the pure liquids needed for computations are presented in Table I for various temperature. Experimental and calcu- lated vapor pressures for the aMS-TOL-PaMS mixtures are listed, as function of x~, in Table II at four temperatures from 298 to 313 K. ...

Biodegradation data in water were not available(SRC, 2012).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,3-diaminotoluene, which has a vapor pressure of 5.53X10-4 mm Hg at 25 °C(2), will exist in both the...
particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-methyl-1,4-benzenediamine, which has an estimated vapor pressure of 3.4X10-3 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient ...

It can be seen from the data in Table 1 that for the three prepolymers of different molecular weight, nitrogen was effective at lowering the residual TDI level to about 0.1 wt % compared to Runs 1, 3 and 6 in which no nitrogen was used. Run 3 also shows that increasing the pressure ...

It is to be seen from the previous Table that the catalyst produces a much higher conversion than the thermal process at a given temperature. It is also to be noted that considerably more of the C3product is acrylonitrile rather than propionitrile. This, too, is in contrast to the thermal ...
(A), corresponding to the recorded lines, were determined. In Table I, the relative intensities are given in terms of the symbols VS=very strong, M=medium, W=weak, etc. It should be understood that this X-ray diffraction pattern is characteristic of all the species of ZSM-22. Ion ...
