VIII shows the effect of ionic strength on the interaction between ionics and POE nonionics. In the catlonlc-nonlonic

VIII shows the influence of base octane on the relative fractional ZSM-5 replacement rate required to achieve a 1 RON boost. Model estimates show that half as much ZSM-5 is required to achieve a 1 RON 0.4 MON boost at a base octane of 88 as compared to an application with a base octane of 92.

VIII shows the method used to calculate the diaromatics factor. The data for these calculations are derived from Table II, which shows that the diaromatic fractions from the three slurry oils have an aromaticity of approximately 0.8. The calculation shows that approximately 50.2 of the diaromatic molecules remain in the slurry oil. Similar calculations with a number of reduced crudes and slurry oils derived from those reduced crudes has indicated that approximately 51.5 of the diaromatic molecules remain in the slurry oil.

VIII shows the phosphorus balance of zinc-fed and non-zinc-fed rats supplemented with 0.8 calcium and or phosphorus. A dietary level of 0.75 zinc was associated with decreases in the apparent retention of phosphorus, and these data support the findings of Sadasivan . Calcium supplements were associated with slight increases in the retention of phosphorus, while phos-

VIII shows the residues of DDT at harvest on Rome Beauty and Winesap apples in the Mississippi Valley. The plot treatments are the same as for Jonathan and Starking Delicious apples except that a seven-spray schedule was used. The residues at harvest shown in Table VIII are greater than those in Table VII. A comparison shows that when six cover sprays of DDT are applied without adhesives the harvest residues are approximately 7 p.p.m. or slightly more. If, however, seven cover sprays are applied, the residues may exceed 9 p.p.m. of DDT, unless the concentration is reduced to less than 1 pound of DDT in 100 gallons.

VIII shows the results of a CH3—CH CD2 isomerization run. Product analysis was carried out by IR and mass spectrographic analysis.

VIII shows the spectral expectations for according to a Dsa symmetry. As has already been stated, only four n.v. are infrared-active, while seven n.v. should be found in the Raman spectrum.

VIII shows the structure of the substrates that have been used in comparative studies by the New Hampshire group. Some of these substrates are quite hindered, but, with the NMDPP, CAMPHOS, DIOP, and ACMP catalysts, quantitative yields are usually obtained under the extended reaction conditions described above.10 The MDPP catalyst does not give a good yield in most instances even under extended conditions.

VIII shows the total storm rainfall and radionuclide depositions measured at each collection site. The storm description given earlier noted the diminishing rainfall as the frontal system moved down the coast. The total collected rainfall decreased from 86 mm. at Crescent City almost smoothly to the low of only 3 mm. at Piedras Blancas. The deposition of the three radionuclides follow a similar pattern the con-

VIII shows the yield and approximate elemental composition of the composite liquid product from these processes. The SCT-SRC and SRC-I residual products were assumed to be liquids for this comparison. SCT-SRC plus upgrading gives a liquid yield almost equivalent to the SRC-I process, but the liquid is of significantly higher quality

VIII summarises data to allow an approximate budget of water humus in the ocean. It is assumed that the annual decrease as a result of oxidation, aggregation and adsorption on the surface of particles with their subsequent sedimentation, equals its input.

VIII summarizes aldicart fate and transport results for the 5-year leaching assessments, including the percent of applied aldicart predicted to leach below 2 meters and soluble concentrations at 2 meters. These soluble concentrations are described as plume11 and average . The plume concentration has been arbitrarily defined as an average of a continuous six-month period of high aldicarb concentration at the 2-meter depth, which occurs before the next application of aldicarb. This recognizes that aldicarb does, in fact, move with a plume and the plume will pass the 2-meter mark for approximately a 6 month period. For a May application, the plume usually reached the 2-meter mark by June.

VIII summarizes major legislation which impacts the chemical industry with society s expectations for safe materials and a clean environment. The chemical engineer has a vital role to play in assuring that products meet these requirements.

VIII summarizes some of the results obtained with isotopic carbon compounds in the synthesis of long-chain fatty acids. Several examples are given below to indicate the role of 2-carbon fragments in the formation of the fatty acids.

VIII summarizes the cumulative uptake rates for mercury in fish from Cranberry Lake and Stillwater Reservoir. Uptake rates were derived by dividing the mercury concentration by the age of the fish, resulting in mg kg body weight-year. Whereas this method of calculating uptake rates is useful in determining trends of mercury accumulation in fish for a number of successive year classes, it does not reflect true instantaneous accumulation rates from year to year due to the nature of the calculation. It is apparent that average uptake rates for fish in both lakes increases as one proceeds fron lower to higher trophic levels. A lack of fish from a diverse number of age groups preeludes the use of uptake rates in defining year class composition for most fish speoies analyzed.

VIII summarizes the cycloaddition reactions of azomethine ylides with maleimides and maleic anhydrides. The upper part of the table involves endo-selective cycloadditions and the lower part nonselective reactions. Endo selectivity is closely related to the substitution pattern of the azomethine ylides used. The azomethine ylides that show high endo selectivity to these cyclic olefins bear an ylide-stabilizing substituent of the carbonyl or cyano type on the ylide nitrogen is equally important.

VIII summarizes the effect of polymerization temperature, initiator type, and activation with ultraviolet radiation on the conversion of VCM. Since this is based on research dealing with determining the degree of syndio-tacticity produced on polymerization, these data only serve to indicate that the rate of PVC formation, in bulk, is usually substantially greater than indicated in the copolymerization experiment described above. In the

VIII summarizes the idealized electron accounting associated with electrochemical reduction of the divalent metal ion complexes of TAAB . In methanol solution, these multiple one-electron processes are followed by a very complex poly-electron wave

VIII summarizes the investment and operating requirements for the H-Oil unit and its attendant facilities, and Table IX compares investment and operating costs for the naphtha and crude oil based facilities. Data on the ethylene plant investment and operating costs were taken from the paper by Freiling, Huson, and Tucker . Offsite investments have been taken at 30 of process investment for the naphtha case, as well as for the ethylene plant portion of the crude oil case. For the H-Oil unit and its associated units offsites have been estimated at one-half of this rate—15 . This lower value has been used since the H-Oil system will add little to the storage requirements, and all utilities have been priced to cover the capital requirements for their production.

VIII summarizes the physical processes that affect the evolution of aerosol in a unit volxame of atmosphere. To develop the general dynamic.equation governing aerosol behavior let us assxime that the aerosol is composed of liquid droplets of M chemical species. We let c denote the concentration of species i in a droplet, i 1,2,..., M, and Dp denote the diameter of the particle. We then define n as the size-composition distribution function, such that n dDp dc. .. dcj is the n umber of particles per unit vol ume of atmosphere at location r at time t of diameter Dp to Dp dDp and of composition c to spegies
