Provide a reaction mechanism of polyurethane foam using castor oil, glycerol, silicon oil and trimethylamine and water
In our class demo on polyurethane, I combined toluene diisocyanate and glycerol (see structures below), which undergo an addition polymerization reaction (the two monomers simply combine without the loss of any atoms). In this reaction, the isocyanate group of the toluene diisocyanate combines with an alcohol of the glycerol to form an ester-like bond. он a. Draw the product of this reaction. I was disappointed in class by the lack of a "wow-factor" in this demo so I added water....
Please provide a clear solution for the above example. The correct answer is provided. Castor Oil in a Steel Pipe What nominal size of steel pipe should be used to carry 0.2 ft3 s-1 of castor oil at 90°F (μ-0.085 lb s ft-2) along a horizontal distance of 0.5 miles with an allowable pressure drop of 10 psi? Assume S 0.85. Be certain to verify any assumptions made regarding the flow regime. Answer(s): 12.7 inches select next nominal as 14...
