Desorption of Isoprene from Synthetic Rubber Latex Effect of Pressure, Agitation, and Latex Depth

Effect of Temperature and Agitation

“…The two lines are drawn parallel, as the data points suggest, indicating that the effect of depth is the same at all driving forces. This is not in agreement with the results of the other study (1). It is felt that the data presented here are too few and not sufficiently accurate to be significant.…”

“…as were the data obtained in the other study (1). The scope of the present investigation, together with the recommended values of K', a, and ß in Equation 1, is presented in Table I.…”

“…Comparison with Other Study. It is possible to make a few comparisons of the results presented here with those presented in the preceding paper (1). These comparisons are shown graphically in Figure 9.…”

“…Isoprene content of the latex before venting begins is determined from the initial equilibrium pressure, ir*, and a plot of the equilibrium data for the system. These data are summarized in the preceding paper (1). p* + pi = ir* -p"pa = 513 -55 -2 = 456 mm.…”

“…The experimental venting apparatus is shown in Figure 1. Essentially, it consisted of two chambers: one to contain the 1 Present address, Distillation Products Division, Eastman Kodak Company, Rochester, '. Y.…”
