    摘要: Ethyl acetate is produced in good yield by reacting ethylene with acetic acid in the presence of a catalyst comprising a tungstophosphoric acid of which 10-90% of the total amount of proton is replaced with a member selected from the group consisting of (a) cesium metal cation, (b) a combination of cesium metal cation and at least one cation selected from alkali metal cations other than cesium cation, and (c) a combination of cesium metal cation and at least one cation of iron group metal cations.

    摘要: Cyclohexyl acetate is produced by reacting acetic acid with cyclohexene in the presence of a heteropolyacid mainly composed of oxides of tungsten as a catalyst. The heteropolyacid may have water of crystallization adjusted to the amount of average 3.0 molecules or less per one molecule of the heteropolyacid. Cyclohexyl acetate can be produced in high selectivity and high conversion. The catalyst is effective even at a low temperature and stable even at a high temperature.

    摘要: The invention provides a sound-reproducing apparatus and a high frequency interpolation-processing method in each of which high frequency interpolation processing having a light burden imposed thereon can be executed. Compressed audio data is decoded by a decoder (202a) and the resulting audio signal is transmitted to a harmonizer (209a). Auxiliary information such as a sampling rate and a bit rate contained in the decoded audio signal is read out by a header reader (209b) and is transmitted to a harmonizer (209a). Communication of signals from/to respective portions is made through a bus (210). The harmonizer (209a) has a preset for an interpolation band obtained in accordance with a format and a sampling frequency of the compressed audio data, and executes processing by referring to file information transmitted thereto from the header reader (209b).
