Suitable control of the humidity can contribute to electric energy savings. However, the present dehumidification system has many weak points. The liquid desiccant air-conditioning system has recently gained growing interest from the stand point of reducing energy consumption during dehumidification. In order to find the appropriate ionic liquids(ILs) as a desiccant for the liquid desiccant air-conditioner system, we conducted a systematic evaluation of the humidification capability of 16 types of ILs. Among the tested ILs, tributyl(methyl)phosphonium dimethyl phosphate([P4441][DMPO_4]) exhibited the best dehumidification capacity and had a less corrosive effect on four types of metals as possible piping materials. It should be noted that this [P_(4441)][DMPO_4] has a very stable nature and produced no odor while conducting the experiment and storing for over 1 year at room temperature under ambient conditions. Furthermore, it was revealed that a 77%(w/w) aqueous solution of [P4441][DMPO_4] worked as an efficient desiccant liquid for the liquid desiccant air-conditioner system.

The cracking of polyolefins, especially polyethylene in the molten state was effectively catalyzed by the powdery spent FCC （Fluid Catalytic Cracking） catalyst which was dispersed in it. The activation energy of the catalytic cracking of polyethylene was about 74 kJ/mol. The cracked product was naphtha and middle distillate as the major product and gaseous hydrocarbon （C1-C4） as the minor product while little heavy oil was produced. The chemical compositions of the product were： aromatic hydrocarbons, isoparaffins and branched olefins, whereas that of the non-catalyzed products were： n-olefins and n-paraffins with minor amount of dienes with increasing the process time. Additionally, the product pattern shifted from naphtha rich product to kerosene and gas-oil rich product. However, any catalytic product showed low fluid point （〈 -10 ℃）, while that of the non-catalyzed product was as high as 40 ℃. Catalyst could process, more than 100 times by weight of polyethylene with fairly small amount （- 30 wt%） of coke deposition. Spent catalyst gave higher hydrocarbons while fresh catalyst gave gaseous product as the major product. Other polyolefins such as polypropylene and polystyrene were tested on same catalyst to show that their reactivity is higher than that of polyethylene and gave the aliphatic products, alkyl benzenes and C6-C9 iso-paraffins as the major product. Product pattern of the cracked product suggested that the reaction proceeded via the primary reactions making paraffins and olefins which were followed by the isomerization, secondary cracking, aromatization and hydrogen transfer which based on the carbenium ion mechanism.

Seven organophosphoric acid triesters （OPEs） and eight polycyclic aromatic hydrocarbons （PAHs） in black cicadas were measured to determine the concentration levels and to investigate how the cicadas are affected by soil contamination. Adult cicadas, nymphal exoskeletons, and soils were sampled in Higashi Osaka, Japan. Four OPEs and six PAHs were detected in the adult cicadas. The total concentrations of OPEs and PAHs ranged from 27.2 ng/g to 824 ng/g and from 4.30 ng/g to 270 ng/g, respectively. Four OPEs and five PAHs were detected in the nymphal exoskeletons. The total concentrations of OPEs and PAHs ranged from 184 ng/g to 1830 ng/g and from 40.3 ng/g to 970 ng/g, respectively. In the soils, three OPEs and six PAHs were detected at the same concentration levels as those detected in the adult cicadas. Significant correlations were observed in the micropollutant concentrations between soils and adult cicadas, and between soils and nymphal exoskeletons. This trend indicates that black cicadas accumulate OPEs and PAHs from contaminated soils.
