Title: THE OXIDATIVE DEGRADATION OF LARGE MOLECULES

Abstract

Oxidative degradation studies were made on several polymeric materials. Polyethylene, both low and high density, shows a slower rate of reaction for the Ziegler type (high density). The rate data can be interpreted by the Elovich equation for heterogeneous reaction at a gas solid interface. In a similar manner polystyrene and deuteropolystyrenes were studied both by carbonyl development and oxygen adsorption. The results indicate a free radical mechanism via peroxide formation. Owing to the free radical nature of the process, the introduction of radicals by the irradirtion of polymers with gamma radiation from Co/sup 60/ was undertaken. (auth)

  • The research was designed to accomplish the following objectives: Determine the effects of pH, temperature, and polymer concentration on HPG solution degradation by enzyme, oxidative (ammonium persulfate), and catalyzed oxidative breakers (ammonium persulfate with triethanolamine); Identify the appropriate breaker system for HPG solutions in the temperature range of 120 deg F - 140 deg F; and Determine the temperature range for HPG solutions where chemical breakers are not necessary to degrade the fluid.
  • The Gas Research Institute has initiated an extensive hydraulic fracturing research project to improve the understanding, modeling and implementation of the hydraulic fracturing process. As the Lead Technical Contractor for the GRI Tight Gas Sands program, S. A. Holditch and Associates, Inc. has initiated research into improving the understanding of fracture fluid rheology. The purpose of the report is to summarize the research conducted by S. A. Holditch and Associates to examine the variables affecting crosslinked HPG gel degradation by enzyme oxidative, and catalyzed oxidative breakers.
  • The objective of this program was to determine the toxic fume and fire hazards of variously treated mine materials compared with virgin or untreated compositions under conditions approximating those likely to be encountered in underground mines. An apparatus was designed and constructed that was capable of simulating varying conditions of temperature, flow, atmosphere with provision for accommodating varying sample thicknesses, total and intermittent product collection, and continuous parameter monitoring. Toxic load assessments were obtained for all of the test conditions. The fire hazards presented by the conveyor belts were higher than that of the NCS-treated woods; toxic hazards were comparable.
  • This report gives results of a study of organic acid-degradation conjugated with sulfite oxidation under flue-gas desulfurization (FGD) conditions. The oxidative degradation constant, k12, is defined as the ratio of organic-acid degradation rate and sulfite oxidation-rate times the ratio of the concentrations of dissolved S(IV) and organic acid. It is not significantly affected by pH or dissolved oxygen in the absence of Mn or Fe. However, k12 is increased by certain transition metals such as Fe, Co, and Ni and is decreased by Mn and halides. Lower dissolved S(IV) magnifies these effects. A free-radical mechanism was proposed to describe themore » kinetics. Hydroxy and sulfonated carboxylic acids degrade approximately three times slower than saturated dicarboxylic acids; while maleic acid, an unsaturated dicarboxylic acid, degraded an order of magnitude faster. A wide spectrum of degradation products of adipic acid were found, including carbon dioxide (the major product), smaller dicarboxylic acids, monocarboxylic acids, other carbonyl compounds, and hydrocarbons.« less
  • The ligninolytic fungus Phanerochaete chrysosporium oxidized phenanthrene and phenanthrene-9,10-quinone (PQ) at their C-9 and C-10 positions to give a ring-fission product, 2,2'-diphenic acid (DPA), which was identified in chromatographic and isotope dilution experiments. DPA formation from phenanthrene was somewhat greater in low-nitrogen (ligninolytic) cultures than in high-nitrogen (nonligninolytic) cultures and did not occur in uninoculated cultures. The oxidation of PQ to DPA involved both fungal and abiotic mechanisms, was unaffected by the level of nitrogen added, and was significantly faster than the cleavage of phenanthrene to DPA. Phenanthrene-trans-9,10-dihydrodiol, which was previously shown to be the principal phenanthrene metabolite in nonligninolyticmore » P. chrysosporium cultures, was not formed in the ligninolytic cultures employed here. These results suggest that phenanthrene degradation by ligninolytic P. chrysosporium proceeds in order from phenanthrene -> PQ -> DPA, involves both ligninolytic and nonligninolytic enzymes, and is not initiated by a classical microsomal cytochrome P-450. The extracellular lignin peroxidases of P. chrysosporium were not able to oxidize phenanthrene in vitro and therefore are also unlikely to catalyze the first step of phenanthrene degradation in vivo. Both phenanthrene and PQ were mineralized to similar extents by the fungus, which supports the intermediacy of PQ in phenanthrene degradation, but both compounds were mineralized significantly less than the structurally related lignin peroxidase substrate pyrene was.« less
