Abstract

Liquid-phase oxidation of chloro- and nitrotoluenes with dilute nitric acid at 180-250/sup 0/C under pressure allows the corresponding benzoic acids to be obtained with high yield. The processes that occur at various points in a plug-flow reactor can be brought into a certain correspondence with the processes occurring through time in a batch reactor, if the temperatures, initial reactant ratios, and character of heat and mass exchange between adjacent microvolumes are equal. Valuable information for evaluating the distribution characteristics of gas formation can be gained from an analysis of the kinetics of oxidation and the rate of pressure buildup when the reaction is conducted in a small closed thermostatted volume with known initial ratio of the liquid and gas phases. The model object selected for study was p-nitrotoluene. The oxidation of p-nitrotoluene with dilute nitric acid was carried out in titanium cells with volumes of 40 and 80 mL.

Miscellaneous Roman, F

A method was developed for determination of aluminum in biological samples by anion exchange chromatography and neutron activation analysis (NAA). The samples were digested with nitric acid at 65{degree}C, converting the aluminum to Al{sup +3}. The remaining solids were dissolved with dilute tiron solution, and the pH adjusted to six with ammonium hydroxide. The tiron forms a negative complex with aluminum, which is retained on the anion exchange resin. To remove the interfering ions ({sup 31}P, {sup 24}Na, {sup 37}Cl) present in biological material, ammonium citrate was eluted through the resin. The aluminum was stripped from the resin with nitricmore »« less
Nitric-phosphoric acid oxidation of solid and liquid organic materials

Conference Pierce, R; Smith, J; Poprik, D

Nitric-phosphoric acid oxidation has been developed specifically to address issues that face the Savannah River Site, other defense-related facilities, private industry, and small-volume generators such as university and medical laboratories. Initially tested to destroy and decontaminate SRS solid, Pu-contaminated job-control waste, the technology has also exhibited potential for remediating hazardous and mixed-hazardous waste forms. The process is unique to Savannah River and offers a valuable alternative to other oxidation processes that require extreme temperatures and/or elevated pressures. To address the broad categories of waste, many different organic compounds which represent a cross-section of the waste that must be treated havemore »« less

Mechanistic studies of nitrations and oxidations in solutions of dinitrogen pentaoxide in nitric acid

Miscellaneous Willmer, R

Mechanisms of nitrations in solutions of dinitrogen pentaoxide in nitric acid of 1,2,4-trichloro-5-nitrobenzene and 1,2-dichloro-4-nitrobenzene have been proposed. The kinetics and products of the nitration, in the title medium, of substantially deactivated benzoic acids and benzaldehydes have been investigated. Kinetics of nitration of some substituted benzoic acids in nitric acid solutions containing dinitrogen pentaoxide or nitronium trifluoro-methanesulphonate (nitronium triflate) have been compared. Rate coefficients for reactions in dinitrogen pentaoxide solutions were generally similar to those from nitronium triflate solutions of the same estimated nitronium ion concentration. Yields of aromatic products of nitration of some benzoic acid derivatives in the nitricmore »« less

The pot overflowed and aluminum nitrate and aluminum oxide filled about half the volume of the Hg trap. The thermocouple for liquid level control didn't sense the high level soon enough. The feed valve for the gravity feed line did not open enough, therefore the pot operated at a low level for the greater part of the filling period. It took 9 hrs of filling tomore »« less
Oxidation of Glycolate in the Defense Waste Processing Facility (DWPF) Recycle Collection Tank - 20305

Conference Siegfried, M.; Lambert, D.; Ramsey, W.; ...

The Savannah River Site's Defense Waste Processing Facility (DWPF) operations are being upgraded with the introduction of the Nitric-Glycolic Flowsheet. Glycolic acid has been shown superior to formic acid as the reducing acid used during chemical processing. The new flowsheet improves or maintains necessary parameters such as 1) reduction of mercury, 2) adjustment of feed rheology and 3) adjustment of melter oxidation/reduction potential. Further, the potential for catalytic hydrogen generation in DWPF processing is virtually eliminated. DWPF process condensates are collected and returned to the SRS Concentration, Storage and Transfer Facilities (CSTF). The Recycle Collection Tank (RCT) collects off-gas condensatemore »« less
