    Notes: The reaction of maleic anhydride (MAH) with molten copolymers of ethylene with methyl acrylate and vinyl acetate in the presence of a peroxide catalyst yields soluble, maleated copolymers containing appended units of MAH, accompanied by insoluble, crosslinked copolymers. The amount of crosslinking that occurs in the presence of the peroxide alone is increased in the presence of MAH-peroxide. The crosslinking is suppressed in the presence of stearamide and caprolactam.

    Notes: The reaction of EPR with dicumyl peroxide at 180°C or t-butyl perbenzoate at 140°C resulted in the formation of a fraction insoluble in cyclohexane at 22°C. The presence of maleic anhydride (MAH) in the EPR-peroxide reaction mixture increased the amount of insoluble polymer, whose concentration decreased as the peroxide concentration increased. The [η] of the cyclohexane-soluble polymer decreased and the MAH content increased as the peroxide concentration increased at constant MAH concentration. The [η] and the MAH content of the soluble polymer increased as the MAH concentration increased at constant peroxide concentration. The EPR-peroxide and EPR-MAH-peroxide reaction products were soluble in refluxing xylene and could be fractionated by precipitation with acetone. The presence of stearamide in the EPR-MAH-peroxide reaction mixture decreased the amount of cyclohexane-insoluble polymer, indicative of decreased cross-linking, but the [η] of the soluble EPR-g-MAH increased, indicative of decreased degradation, analogous to the effect of stearamide in the MAH-peroxide reactions with LDPE and PP, respectively.

    Fine sediment erodibility in Lake Okeechobee, Florida (2021)

    Description: The critical need to predict the turbidity in water due to fine-grained sediment suspensionunder wave action over mud deposits for sedimentation and erosion studies, as well assorbed contaminant transport, is well known. Since fall velocities of fine sediment particlesare very small, they can be easily transported by hydrodynamic flows such as waves andcurrents. The presence of these particles in the water column affects accoustic transmission,heat absorption and depth of the eutrophic zone (Luettich et al., 1989). Because these sedimentsalso have a strong affinity for sorbing nutrients and toxic chemicals, sediments whichhave been deposited on the bottom may function as a source of contaminants to the watercolumn if they are disturbed by eroding forces resulting, for instance, from wave action. Anoutstanding example of a water body for these problems is Lake Okeechobee, the largestshallow lake in Florida. This lake shows typical signs of artificial eutrophication mainly dueto increased phosphorus loading associated with the surrounding region. Resuspension of sediment at the bottom of Lake Okeechobee composed of fine-grainedmaterial has been examined. A sediment transport model was used to simulate likelytrends in the evolution of the vertical suspended sediment concentration profile resultingfrom wave action, and the corresponding eroded bed depth was calculated through massbalance. Requisite information on characteristic parameters and relationships related tofine sediment erodibility were derived from field sampling of bottom sediment in the lake,and through laboratory experiments using this sediment and lake water.

    Notes: The first phase equilibrium data are presented for Structure H hydrates. The data represent the initial formation of these hydrates from methane, with adamantane -  a previously determined Structure H former. Temperature and pressure conditions are consistent with hydrocarbon production/transportation/processing facilities. Structure H hydrates are shown to contain molecules indigenous to petroleum. which may not be present in natural gas.

    A thermodynamic model for structure-H hydrates (1994)

    Notes: A statistical thermodynamics model based on the original work of van der Waals and Platteeuw is presented for structure-H hydrates. The model is an extension of the hydrate prediction method generalized by Parrish and Prausnitz for structure-I and-II hydrates. Four structure-H-forming systems, methane+ adamantane, methane+ neohexane, methane+isopentane, and methane+methylcyclohexane, were considered. Optimized Kihara core parameters are presented for each of the large hydrocarbon guest molecules. The optimized reference chemical potential difference and reference enthalpy difference for structure-H hydrates are also presented. The results show good agreement with the experimentally determined phase-equilibria conditions. A sensitivity analysis is presented for the parameters in the model, and their relative order of influence on the accurate evaluation of the quilibrium pressure is determined.

    Four environment model of mixing and chemical reaction. Part I. Model development (1983)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A new mathematical model (the four environment model) to describe turbulent flow chemical reactors with complex reactions and separate reactant feed streams is developed. The feed stream residence time distributions, the batch chemical kinetics, and a single turbulent micromixing parameter, which may be estimated from direct turbulence theory, are required as input information to the model. The model is computationally efficient as it involves only ordinary differential equations.

    Four environment model of mixing and chemical reaction. Part II. Comparison with experiments (1983)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The four environment model, which was developed in Part I, has been compared with three extensive sets of experimental data from plug-flow and stirred-tank reactors with unmixed feedstreams and a single chemical reaction. The data sets have been accurately reproduced with a single value of the micromixing parameter (RS), and the “best fit” value of RS for each data set was close to the value estimated from the Corrsin-Rosensweig turbulent mixing theory. This lends support to the turbulence analogy suggested in Part I. Simulations of competing reactions of the parallel-consecutive type are used to discriminate between the four and three environment models with the four environment model providing much more realistic predictions.
