    Abstract 13C separation at a laboratory scaled-up level by the13C-selective InfraRed MultiPhoton Dissociation (IRMPD) of CHClF2 in the presence of Br2 has been investigated in a flow reactor. With a complete scaled-up system including a flow reactor, an industrially reliable TEA CO2 laser with longer pulse duration and a product-separation set-up for13C separation, it has been attempted to optimize the parameters suitable for large-scale production of the carbon isotope. The optimization of13C separation parameters, such as laser fluence, laser frequency and the partial pressure of CHClF2 and Br2 was tested under static conditions. By irradiation with longer pulses, a lower optimum pressure for a high13C-production rate was determined. Furthermore, the separation process was scaled in the flow system to examine the13C-production rates,13C atomic fractions in the CBr2F2 products and13C depletions in the CHClF2 reactants at different flow rates and laser repetition frequencies. The data obtained from the flow tests demonstrated a 40 mg/h production rate for CBr2F2 at 65%13C by using a 40 W (4 J, 10 Hz) laser beam focused with a lens of 120 cm focal length. If the reliable TEA CO2 laser is operated with 100 W (10 J, 10 Hz) output, the production rate of CBr2F2 for13C at 60% of 200 mg/h can be attained. The measurements of the spatial profile of the focused laser beam imply a 2 g/h production rate for the 60%13C product for an incident power of 200 W (20 J, 10 Hz).

    Abstract The antimicrobial ceramics (AC) based on hydroxyapatite (HA) were made in a wet chemical process with additions of AgNO3, Cu(NO3)2 · 3H2O and Zn(NO3)2 · 6H2O. The ACs were composed of metal-ion substituted hydroxyapatite and nitrate–apatite, which was identified by X-ray diffraction. The viable count and turbidity measurement was adopted to observe the antimicrobial effects of the various ACs. The aerobic Escherichia coli was used in the study. An obvious antimicrobial effect against E. coli was observed in Ag+ AC. In contrast to Ag+ AC, it was difficult to ascertain any bactericidal effect in the case of Cu2+ and Zn2+ AC. The bactericidal effect of Ag+ was observed using a dialysis tube experiment. This suggests that Ag+ dissolved out and reacted with E. coli, thus inhibiting its growth. © 1998 Chapman & Hall

    Summary We are investigating wood decay biocides that are both effective in protecting wood from decay and more environmentally compatible than other biocides. A series of halophenyl sulfonamides were synthesized and characterized by infrared and neuclear magnetic resonance spectroscopy. Wood impregnated with these compounds was tested for resistance to decay as well as water leaching. Wood impregnated with para-iodophenyl or para-fluorophenyl para-tolyl sulfonamides resisted decay by brown- and white-rot fungi. For wood impregnated with para-iodophenyl para-tolyl sulfonamide, threshold retention with the brown-rot fungus Gloeophyllum trabeum was 9.1 mmol/ 100 g solution for unleached blocks. For leached blocks, weight loss was very high (24.6%), which indicated that threshold retention will be substantially higher than 9.1 mmol/100 g solution. With the white-rot fungus Coriolus versicolor, threshold retentions were 2.9 and 5.6 mmol/100 g solution, respectively, for unleached and leached blocks. Leaching of the blocks treated with the iodo compound slightly decreased resistance to decay by C. versicolor. For wood impregnated with parafluorophenyl para-tolyl sulfonamide, threshold retentions with both G. trabeum and C. versicolor were very close to 9.0 and 9.2 mmol/100 g solution, respectively, for leached and unleached blocks. Leaching had a little effect on resistance to decay by both fungi. Wood impregnated with parachlorophenyl or bromophenyl para-tolyl sulfonamide was ineffective in resisting decay by both fungi.

    Notes:
    Summary Properties of wood can be improved by reacting chemicals with hydroxyl groups of wood cell wall polymers. To achieve this improvement in wood properties, bioactive compounds containing hydroxyl groups, such as pentachlorophenol, 3,5-dimethyl phenol, and 2-naphthol, can be reacted with epichlorohydrin to give corresponding glycidyl ethers. The new epoxide formed during this reaction can be used to bond bioactive compounds to wood. This bonding may result in improved wood properties. The objective of this study was to develop a simple procedure for synthesizing glycidyl ethers. The alcohol was reacted with epichlorohydrin and a catalyst and monitored by thin-layer chromatography. Shortwave ultraviolet light was used to detect spots. Resulting products were analyzed for carbon, hydrogen, and in one case, chlorine. Reaction of pentachlorophenol with epichlorohydrin formed only one enantiomeric glycidyl ether, whereas reaction of 3,5-dimethyl phenol with epichlorohydrin led to two enantiomeric glycidyl ethers in a 1 to 3 ratio. Reaction of 2-naphthol with epichlorohydrin also led to two enantoimeric glycidyl ethers in equal amounts. In future research, these glycidyl ethers will be reacted with wood, and their toxicity to wood-destroying fungi in bonded form will be determined.
