    Notes: Supercritical water oxidation of isopropyl alcohol was investigated in a pilot-scale reactor. A computational fluid-dynamics model developed reveals the detailed flow field, chemical-component distribution, temperature distribution, and salt-particle trajectories in the reactor flow domain. The near-wall fluid temperature from the numerical analysis was compared with experimental temperature data. The temperature comparison was within a 3% error band. The effect of the chemical kinetic rate was investigated for four different rates. Turbulent salt-particle trajectories were also calculated to investigate the effect of particle sizes on salt deposit on the wall. Also, a method of calculating the adiabatic reaction temperature was developed to estimate reaction temperatures prior to a full numerical simulation.

    Synthesis and antimalarial activities of structurally simplified 1,2,4-trioxanes related to artemisininDedicated to Prof. Shigeru Oae on the occasion of his seventy-fifth birthday. (1995)

    Notes: Eleven derivatives of the clinically useful, antimalarial, 1,2,4-trioxane artemisinin have been synthesized in only several steps from commercial cyclohexanones. Of these simple, tricyclic 1,2,4-trioxanes, 10 showed considerable in vitro antimalarial activity, with one being as potent as artemisinin. Some structure-activity relationship generalizations are made from this series of artemisinin analogs. Triethylsilyl hydrotrioxide (Et3SiOOOH), prepared in situ from ozone and triethylsilane, is shown to be a mild, fastacting, and effective dioxetane-forming reagent with vinyl ethers and with a vinyl thioether on relatively small (50-100 mg) scale.
