The rate of leaching of a new plasticizer, Hatcol 200 (a l,3-dihydro-l,3-dioxo-5-isobenzofuran carboxylic acid branched oxo ale. ester) [75882-00-73 from PVC by serum was IX that of I. Normal serum incubated for 3 wk with PVC strips plasticized with I produced significant growth inhibition of human diploid fibroblasts whereas Hatcol 200 stored for A wk showed no effect. Thus, Hatcol 200 is an ideal replacement for I, based on PVC tensile properties and in vitro data.

No toxic effect of any samples was obsd. for polyethylene (Granoten), whereas all samples of routinely sterilized rubbers had an immediate toxic effect on stabilised lines of cells and caused contact tissue necrosis in the subcutis of the exptl. animals. Routinely sterilized polyamide and PVC did not cause direct-contact changes in the stabilized lines of cells or any contact necrosis in the s.c. tissue, but their exts. had toxic effects on HeLa cells and on rat spermatozoa. dm - 9002-86-2; 9002-88-4 6 SI CC AU AD TI SO PT CY LA CA/096/148725T CA/161002 Boettner EA ; Ball GL ; Hollingsworth Z ; Aquino R Dep.

A mixt. of CO and Ar, N2, H20, NH3, CF4 was used for glow discharge. The resulting I had a double-layered surface composed of densely crosslinked outer layer and slightly crosslinked inner layer. The total thickness of the crosslinked layers was 2000.apprx.3000 .ANG.. The crosslinking took place by the recombination of radicals formed by the cleavage of C-Cl bond and/or by binding of the radicals and plasma-dissocd. species. The wettability of the surfaces which were exposed to the plasma of various gases, except for CF4 or fluorohexyl acrylate, was increased. In addn., the adhesiveness to silicone was increased. The platelets strongly adhered to the discharge-treated surfaces.

The recently received draft designs for a cyclo after-burner (plus assocd. scrubbers and filters* etc.) offer an attractive method for dispensing of the volatile products of pyrolysis. The off-gases arising from the pyrolysis of empty polypropylene pots and of a pot of waste simulant were analysed by gas chromatog. Quant, compn. data were obtained to account for .apprx.70/ of the gas vol.* and hypotheses as to the nature of the remainder were formulated. In the run with simulated waste* the NaOH scrubber provided effective removal of acid gases. A cyclonic afterburner design was proposed to handle off-gases from a 20 kg/h pyrolyzer which would be used to dispose of shredded/packaged Pu-contaminated materials. A hazard assessment was undertaken.

Development of the feasibility study was based on known characteristics of LWR waste and on operating data compiled for the Mound Cyclone Incinerator since 1975. Feed spiked with several isotopes found in LWR waste was burned in the la.b.-scale cyclone incinerator, and samples were collected and analysed. From these data, the applicability of cyclone incineration was demonstrated, and an efficient scrub liquor compn. was chosen for the offgas treatment system.

The exposures included the primary testing of 12 liners in contact with 6 wastes for 3 yr, immersion tests of 12 polymeric membranes in 9 wastes for .ltoreq.2.25 yr, and roof exposure of polymeric membranes and wastes. Most of these results hav'e been reported at previous research symposia and in interim reports. The effect of minor amts, of org. constituents in a waste can have significant effects on liner materials on prolonged exposure. Swelling of a membrane results in the loss of phys. properties such as tensile strength, elongation at break, and tear strength. Major factors in the swelling of a membrane in a given waste are its soly. parameter with respect to that of the waste, its degree of crosslinking and crystallinity, and the presence of water sol. constituents in the membrane compd. No single liner material in the test program appears to satisfy all of the requirements for all wastes. The complexity of the various waste streams requires that compatibility tests must be run to demonstrate the durability of the lining material under consideration with the waste which is to be impounded. Liners based on polymers with crystallinity appear to be more resistant to water and chem. than the other polymeric materials.

This approach is backed by the math, model of the measurement process. It describes the influence of interaction of obsd. radiation with the waste materials and takes into account the geometry of measured waste items. Waste items of a certain shape and vol. loaded with contaminated materials are transformed by the theor. model into spheres of certain radius of ref. materials (1-dimensional model) of which the effective radiation escape probabilities are detd. exptl. The models are further adjusted by measurements with synthetic wastes and by periodic comparison with destructive analyses of selected items from the monitored waste streams. This procedure provides for improvement of error anal, with the no. of waste items monitored, hence reducing systematic errors and improving inventory in waste store. The methodol. and results are presented from verification measurements using passive n techniques on 3 different types of Pu-bearing materials.

For vol. redn. and recovery of Pu from the ash, a pyrohydrolysis process was developed which is the reaction of the waste with steam at 800.degree.. In the constructed line, the combustible waste is shredded, homogenised and tangentially fed into a ring slab reactor made from metal such as Inconel-600. (12606-02-9 Inconel-600) The ring slab space is formed by 2 cylinders, a fixed outside cylinder and a rotating inside cylinder. The reactor is criticality-safe. The material is converted to ash and combustible offgas (H2, CO, hydrocarbons ). Ash falls down through a grate to the bottom gate. The offgas is fed into a burner chamber and oxidised to C02 and H20. then, the Venturi scrubber HCl-gas is absorbed in the H20 at a pH 5, the steam condenses in a heat exchanger, and the offgas (only C02) passes through a fine filter to the stack. This process is also used for waste redn. of spent solvent. At 500.degree., the TBP completely decomps, in the presence of CaO, forming Ca3(P04)2 and butene and butenol. Using a fluidised-bed system, a mixt. of TBP/dodecane and CaO is fed into a sand bed. The offgas is fed to an after-burner or condensed for recovery. 12606-02-95 126-73-8; 630-08-0; 1305-78-8; 1333-74-0', 7440-07-5; 7758-87-4; 9002-86-2J 25167-67-3; 57323-59-8 8108 # 97 SI - CA/095/012219C AU - Wiecsorek H ; Kemmler 6 ; Krause H ; Lahr H AD - Inst.

The main objectives are the redn. of the waste vol., the recovery of the Pu and the transformation of the process residues into a product suitable for final disposal. For this purpose, an inactive demonstration plant with a throughput of 1.5 kg/h was constructed. In the 1st version, the reactor of this plant was a tray reactor of the HEDL type. During test operations, the sedimentation of a residue was obsd. on the tray. The d. of this residue was higher than that of the residue suspended in the reaction acid. Expts. using Ta oxide (d = 8.4 RNW 1734 00010066 PVC PAGE 44 g/cm3) to simulate the Pu oxide (d = 11.5 g/cm3) verified this observation. This means that in active operation a sedimentation of Pu oxide on the tray is to be expected. With respect to these results* a new reactor was developed where the settling of the residue is avoided by appropriate design and high circulation velocity of the reaction acid. The reactor consists of a tube 50-80 mm in diam., which is curved to form a closed loop with an arm length of about I .times. 1 m. Its behavior is very stable. The velocity of the reaction acid in the heater is 0.5-1 m/s. A settling of residues or Ta oxide was not obsd. The throughput attained is comparable to that of the tray reactor* but the space requirement is a factor of 3 smaller, and the vol. of the reaction acid a factor of 4 smaller.

CHEM ABS A convective diffusion model for solute transport in an absorbing tube was applied to the sorption of vitamin A to plastic and glass tubing under clin. perfusion conditions. (68-26-8 Vitamin A) Tritium labeled retinol was used for the study. The tubing had a high capacity for absorption of vitamin A, but the equilibration of concn. (diffusion) within the tubing wall appeared to be relatively slow. Using an effective or apparent wall permeability for vitamin A, the transport model accounted well for the flow rate and tubing length dependence of the sorption phenomena of vitamin A. The amt. of vitamin A lost to the tubing wall from the total parenteral nutrition with multivitamin soln. was less than that from total parenteral soln. alone, presumably due to the presence of surfactants in the multivitamin prepn.
