November 3, 2020 - Draw vapor-liquid equilibrium (VLE) phase diagrams for single compounds or binary systems; residue curves for ternaries. Ethyl alcohol may be converted directly to 1-butanol at 325 °C and 13 MPa (128 atm) over magnesium oxide / copper oxide. A mixture of butanol, hexyl and octyl alcohols, acetaldehyde, butyraldehyde, and crontonaldehyde is obtained when ethanol and hydrogen are passed over magnesium oxide at 200 °C and 10 MPa (99 atm).

Properties of Pure Substances Use the values determined in Part C to construct a phase diagram for t-butanol. Label the x - and y -axes; identify the solid, liquid, and gaseous regions; and label the triple- point and the boiling and freezing points at laboratory pressure. Ternary phase diagrams are used to represent all possible mixtures of three solvents [1]; they are described in Chapter 3.Here, we shall indicate how they should be used to minimize the solvent consumption. Figure 2.1 (top) shows the methanol-chloroform-water ternary phase diagram with the tie-lines in the biphasic domain. Five particular compositions are shown in the diagram: Table 2.1 ... However, most phase diagrams investigated in the lab are simple eutectic ones, despite the fact that complex binary solid-liquid phase diagrams are more common. In this article, the cooling curves of phenol-t-butanol mixtures are measured and the phase diagram of this system is found to give three eutectic points and two congruent melting points. In addition, for a user-specified value of the temperature, the compositions of the 1-butanol-rich phase and the 1-butanol-lean phase are displayed. Our results are validated by benchmarking them with their counterparts obtained from the Aspen-HYSYS process simulator [3] and shown in the diagram by the black triangles.

It was found that t-butanol was the best solvent for TPP of cell lysate to obtain the maximum protein concentration. In the presence of t-butanol, 55 % w/w of protein concentration was obtained in the middle phase. Solvents act in TPP by increasing the buoyancy of the precipitated protein by binding to it, resulting in a middle phase that ...

The first was a rapid phase, which probably represented the distribution of (14)C-t-butyl alcohol from the blood to other body tissues. The second represented a first-order elimination of radioactivity from the blood with a half-life of approximately 8 hr, indicating that (14)C-t-butyl alcohol was being eliminated primarily as metabolic product(s).
