How does aniline react with water?
1. Aniline, a weak base, reacts with water according to the reaction represented above. (a) Write the equilibrium expression, Kb, for the reaction represented above. Kb= [C6H5NH3 +][OH–] [C6H5NH2] 1 point for correct expression (b) A sample of aniline is dissolved in water to produce 25.0 mL of a 0.10 Msolution. The pH of the solution is 8.82.
What happens to the viscosity of anhydrous ethyleneamine After cooling?
The reaction of water with the Ethyleneamine is exothermic, which will initially reduce the mixture viscosity; however, after cooling, the mixture thickens beyond the viscosity of the anhydrous Ethyleneamine.
Are ethyleneamines soluble in water?
Ethyleneamines are soluble in water. However, in the range of 20 to 80 weight-percent water, the added water will result in increased heat of solution, which can be significant depending on the Ethyleneamine. Some Ethyleneamines will also form hydrates, which can cause plugging issues in various processes.
What happens when Ethyleneamines are exposed to air?
Note: When Ethyleneamines are exposed to air, especially in warm weather or in a heated tank, they tend to oxidize and discolor. Note: A minimum tank level must be established before operating a jet mixer. This minimum level is defined as part of the tank / mixer design.
