Energies of organic compounds. Technical progress report. [Ketals, orthoesters, norbonyl ketals]

Description: Two automated reaction calorimetry systems were built and tested. The first made use of a quartz thermometer probe as the temperature measuring element. The second was constructed using a thermister which was part of a Wheatstone bridge. The off-balance voltage from the bridge was measured using the 6 1/2 digit digital voltmeter, and transferred to the microprocessor. The one disadvantage of the first system is the relatively large size of the quartz sensor. The calorimeter systems were used to… more

Solvent extraction of phenols from water

Description: Methyl isobutyl ketone (MIBK) and diisopropyl ether (DIPE) have been evaluated as solvents for extraction of phenols, at high dilution, from water. Equilibrium distribution coefficients (K/sub D/) have been measured for phenol, dihydroxybenzenes and trihydroxybenzenes in both solvents as a function of pH. Particularly for the multihydric phenols, MIBK gives substantially higher values of K/sub D/ than does DIPE. The effect of pH can be described quantitatively through a simple ionization model,… more

Exploratory research, Tasks A, B, C, and D. Final report, August 17-December 31, 1977

Description: SRI International has conducted research on the upgrading of computerized thermo-hydro code calculations and the synthesis of energetic materials. This project comprised four tasks, as follows: Task A included: (1) formulating routines for inverting the P = P(T,V) and V = V(T,P) equations of state when isotherms exhibit a van der Waals' loop; (2) incorporating these routines into the TIGER code so V and T can be used as independent variables in computing thermodynamic functions of liquids exhib… more

High octane ethers from synthesis gas-derived alcohols. Quarterly technical progress report, October--December 1992

Description: The testing of strongly acidic catalysts for the conversion of a mixture of methanol and isobutanol to ethers and hydrocarbons was continued. Under standardized test conditions the catalysts tested this quarter were: phosphotungstic acid supported on zirconia (PW{sub 12}/ZrO{sub 2}), ``niobic acid`` (Nb{sub 2}O{sub 5}xH{sub 2}0), and an iron and manganese doped sulfate-modified zirconia (Fe/Mn/ZrO{sub 2}/SO{sub 4}{sup {minus}2}). The overall activity of these catalysts followed the order of Fe/… more

Synthesis of dimethyl ether and alternative fuels in the liquid phase from coal-derived synthesis gas. Final technical report

Description: Through the mid-1980s, Air Products has brought the liquid phase approach to a number of other synthesis gas reactions where effective heat management is a key issue. In 1989, in response to DOE`s PRDA No. DE-RA22-88PC88805, Air Products proposed a research and development program entitled ``Synthesis of Dimethyl Ether and Alternative Fuels in the Liquid Phase from Coal Derived Syngas.`` The proposal aimed at extending the LPMEOH experience to convert coal-derived synthesis gas to other useful … more

Advanced membrane separation technology for biosolvents. Final CRADA report.

Description: Argonne and Vertec Biosolvents investigated the stability and perfonnance for a number of membrane systems to drive the 'direct process' for pervaporation-assisted esterification to produce lactate esters. As outlined in Figure 1, the target is to produce ammonium lactate by fennentation. After purification and concentration, ammonium lactate is reacted with ethanol to produce the ester. Esterification is a reversible reaction so to drive the reaction forward, the produced ammonia and water mus… more

A PROCESS FOR CONTROLLING INSOLUBLE URANIUM IN ORE CONCENTRATES I. LABORATORY INVESTIGATION

Description: A process has been developed for converting nitricacid-insoluble uranium in ore concentrates into soluble form. Ore concentrates are treated with a reducing agent such ss carbon monoxide or hydrogen at temperatures or 670 to 730 C. In the laboratory, retention times nsoluble uranium vary inversely with the concentration or the reducing agent. Laboratory studies leading to the development of the process are reported. (auth)

Development and evaluation of supercritical fluid chromatography/mass spectrometry for polar and high-molecular-weight coal components: Technical progress report for the period October 1, 1985 - September 30, 1986

Description: Technical progress toward the programmatic goals of developing and evaluating SFC/MS for the analysis of higher-molecular-weight compounds was made in the following areas: Studies have been conducted to characterize the requirements for and to facilitate the transfer of thermal energy to the capillary flow restrictor region. Such studies have resulted in a new interface probe design which allows better transport of higher molecular weight, less volatile compounds decreasing the mass discriminat… more

Preparation and use of Ammonium Diuranate in the Ether Extraction Process

Description: In the ether extraction process, as originally developed, purified uranium dioxide was obtained by evaporation and calcination of the uranyl nitrate solution, followed by calcination of the resultant UO{sub 3}. It was suggested that an alternate procedure might be developed, involving the precipitation of uranium from the nitrate solution as ammonium diuranate. This material could then be calcined to uranosic acid, or reduced directly to the dioxide. It had already been established that ammoniu… more

Design, synthesis, and characterization of novel fine-particle, unsupported catalysts for coal liquefaction

Description: The first task in our proposed study of catalysts for coal liquefaction was to prepare ultrafine dispersed metal sulfide particles by reactive precipitation from solutions of appropriate metal precursors. At this point, equipment to allow us to prepare these air-sensitive materials in an anaerobic environment has been acquired and assembled. Initial experiments aimed at synthesizing iron sulfide particles have been initiated. As part of the investigation of short contact time catalytic coal liq… more

Effect of high magnetic fields on orientation and properties of liquid crystalline thermosets

Description: In this report we provide the first description of the orientation of liquid crystalline thermosets (LCT`s) in field strengths of up to 18 T, as well as the first report of tensile properties for both unoriented and oriented LCT`S. The LCT we have chosen for study is the diglycidyl ether of dihydroxy-a-methylstilbene cured with the diamine, sulfanilamide. Orientation in magnetic fields leads to an increase of almost three times the modulus compared to the unoriented material. These values are m… more

The potential for alcohols and related ethers to displace conventional gasoline components

Description: The United States Department of Energy is required by law to determine the feasibility of producing sufficient replacement fuels to replace 30 percent of the projected United States consumption of motor fuels by light duty vehicles in the year 2010. A replacement fuel is a non-petroleum portion of gasoline, including alcohols, natural gas and certain other components. A linear program has been used to study refinery impacts for production of ``low petroleum`` gasolines, which contain replacemen… more

Dehydration of isobutanol to isobutene in a slurry reactor

Description: The April 1990 Alternative Fuels Proposal to the Department of Energy involved the development of new technology, based on the liquid phase process, for conversion of coal-derived synthesis gas to oxygenated hydrocarbon fuels, fuel additives, and fuel intermediates. The objective of this work was to develop a slurry reactor based process for the dehydration of isobutanol to isobutene. The isobutene can serve as a feedstock for the high octane oxygenated fuel additive methyl tertiary-butyl eithe… more
