Vacuum sublimation of a Zn(III) complex solution produced a pink-colored solid, which was Zn(III) perfhiorotetraphenylporphyrin. NMR analysis of this product showed the absence of pyrrole hydrogen atoms, which is the evidence for complete replacement. Then bivalent iron chloride (FeCl2) was prepared according to the common technique [17]. This compound was then used for Zn(III) ion replacement in a porphyrin ring. For this purpose, the Zn(III) complex was dissolved in dimethylformamide (DMF) and then, with the addition of an FeCl2 solution, also in DMF. The reaction mixture was heated in a steam bath at water boiling point for 5 h. Finally, a dark-brown sediment was deposited, and the solution was colored blue, which is typical of iron(III) perfhiorotetraphenylporphyrin (perFTPhPFe(III)) dissolved in DMF. In this case, the active weight of the catalyst iron(III) perfhiorotetraphenylporphyrin equaled 47.05 mg.

Water (boiling point [bp], 100°C critical temperature [Tc], 374°C critical pressure [Pc], 218 atm) is the most widely examined reaction medinm for solvothermal reactions. Geochemists first applied this techniqne to explore the formation mechanism of minerals and thus quite long reaction periods were applied to... 

The process of extraction of oil with hot water was originally designed by K. A. Clarke and called the hot-water washing process for exploitation of Arthabasca bituminous tar sand [1, 2, 3 ]. The term hot water is used instead of steam or water vapor , because tbe operating temperature (around 90 °C) was maintained near tha water boiling point without ever reaching it [ 4 ].

The molal boiling point elevation constant, fCt, is the difference in boiling points between aim nonvolatile, nonelectrolyte solution and a pure solvent. Boiling point elevation is expressed in units of °C/m and varies for different solvents. Values of for several common solvents are found in Table 14.5. Note that waters value is 0.512°C/m. This means that aim aqueous solution containing a nonvolatile, nonelectrolyte solute boils at 100.512°C—a temperature just 0.512°C higher than pure waters boiling point of 100.0°C.

The temperature used for the gel time test should always be adjusted to the temperature of application of the resin. If the maximum temperature in a glue line during pressing is not higher than 70°C, then the gel test should be performed at such a temperature and not at water boiling point. This is recommended in order to better interpret the behavior of the resin or the resin glue mix under its conditions of industrial application. 

Azeotrope with water boiling point, 760 mm diacetone... 

The problem at hand is how to remove water. Because ethanol and water form an azeotrope, it is possible to remove water from a reaction in this manner, but there are problems. Ethanol and water are miscible (mutually soluble in one another), so the water and ethanol do not separate (form layers) once the mixtrue has been distilled. If a solvent other than ethanol is used to form an azeotrope water and water is insoluble in that solvent, water would separate after the mixture had been distilled. One such solvent is benzene, which forms a binary (two-component) azeotrope with water (boiling point of benzene is 80.1°C) that boils at 69.4°C and is composed of a 91.1 8.9 benzenerwater mixture. Caution benzene is toxic and a suspected carcinogen see Chapter 21.) Refluxing the aldehyde or ketone with at least two equivalents of ethanol in benzene wiU drive the reaction toward the acetal (46) and the benzene-water azeotrope can be distilled off...
