摘要： PROBLEM TO BE SOLVED: To provide a preservative period-extending agent for food having extremely excellent durability of antibacterial effect, having reduced irritating smell, capable of constantly exhibiting stable volatility regardless dry or wet condition and excellent in workability of automatic packaging when it is used in a divided package. SOLUTION: This preservative period-extending agent for food is prepared by supporting allyl isothiocyanate B on active carbon A. The amount of allyl isothiocyanate B supported on 100 pts.wt. of active carbon A is preferably 5-40 pts.wt., more preferably 10-35 pts.wt. It is suitable to use a product of active carbon A, for example, having particle diameters of 0.17-1.7 mm and a specific surface area of 800-1600 m /g as the active carbon A. This preservative period-extending agent for food may be used in a shape of a small bag having air permeability in which the agent is filled.

摘要： PURPOSE:To heighten catalyst activity at low temperature by supporting catalytic components comprised of oxides of iron group metals, rare earth elements and platinum group metals on a support comprised of SiO2 and alkaline earth metal oxides. CONSTITUTION:An aqueous sodium silicate solution is added to an aqueous solution containing an alkaline earth metal nitrate or lanthanum nitrate while stirred, a precipitate deposited after the solution is left still for a set period is washed with water, dried, and fired in air to give a catalyst carrier. Then, after the pores of the carrier are filled with an aqueous solution containing a chloride of platinum-group metal, the carrier is dried, fired, and reduced in hydrogen atmosphere to support platinum group metal on the carrier. Then, the resultant carrier is immersed in a mixed solution of an aqueous iron group metal nitrate solution and an aqueous rare earth element nitrate solution, dried, heated, and reduced to support an oxide of the iron group metal and rare earth element on the carrier.

摘要： PURPOSE:To efficiently manufacture a high-calorie gas which does not contain CO, by passing a raw material gas consisting of a non-combustible component and a combustible component through an adsorption tower packed with specified adsorbents. CONSTITUTION:A packed tower 2 is packed with a dehumidifying adsorbent X (e.g., zeolite) in the upper layer, an adsorbent Y comprising a porous carrier (e.g., silica) carrying 0.5-10mmol/g of a copper compound [e.g., copper (I) chloride], for selective separation of CO, in the middle layer, and a clinoptilolite adsorbent Z in the lower layer so that the volume ratios of X to Y to Z is 0.5:9.5-3:7 and the volume ratio of Y to Z is 1:1-9. A raw material gas (a) consisting of a no-combustible component comprising, e.g., CO2, N2, and H2O and a combustible component comprising, e.g., CO, H2, and a hydrocarbon, and a product gas (b) and/or a discharged gas (c) are brought into a pressure-raising step 1, in which the pressure is raised to 1-50kg/cm G. Then this gas mixture is introduced into an adsorption tower 2 heated to a temperature of 50-200 deg.C, where the non-combustible component and CO are removed, and the product gas (b) is thus obtained. The non-combustible component and CO are then introduced into a step 3, in which the pressure is reduced to atmospheric pressure, and the discharged gas (c) is obtained.

摘要： PURPOSE:To efficiently recover a group VIII noble metallic complex by bringing an adsorbent adsorbing the group VIII noble metallic complex into contact with desorption liquid consisting of a polar soln., organic base and organic phosphorus compd. CONSTITUTION:A group VIII noble metallic complex is adsorbed to an adsorbent by bringing organic liquid incorporating the group VIII noble metallic complex which has a ligand especially the ligand consisting of organic phosphorus compd. into contact with the adsorbent. After adsorption, the organic liquid stuck to the adsorbent is removed with a solvent. Then desorption liquid is flowed on the adsorbent and thereby the complex adsorbed thereto is desorbed. As the desorption liquid, a liquid having the composition consisting of a polar solvent, organic base and organic phosphorus compd. is used. Thereby the complex adsorbed to the adsorbent is efficiently eluted in the desorption liquid.

摘要： PURPOSE:To measure COD in a waste water in a short time by an elution analysis of a sample with an eluent liquid comprising water containing sodium acetate, methanol and acetic acid in the development employing a water gel permeation type column of a fast liquid chromatograph after the removal of suspended matter. CONSTITUTION:An eluent liquid tank 1 is filled with an eluent liquid containing less than 0.5mol/l of sodium acetate, 5-10% cap. of methanol and 5% cap. of acetic acid. The eluent liquid is transferred with an eluent liquid transferring pump 2 and mixed with a small amount (5mul-1ml) of a waste water sample fed from a sample injection inlet 3 after suspended matter is filtered with a microfilter with a bore size of 0.2-0.4mum. After the removal of impurities with a precolumn 4, various oxygen consuming components are separated with a water gel permeation type separation column and then, detected, recorded and analyzed with an ultraviolet detector 6, a recorder 7, a molecular weight calculator 8 and the like. This operation can complete a measurement for only one hour with a simple operation.
