  • Method of preserving article with an oxygen absorbent composition
    Patent number: 5378428
    Abstract: A method of preserving an article which includes enclosing the article and an oxygen absorbent parcel in a container having gas-barrier properties and sealing the container. The parcel is formed by packing an oxygen absorbent composition with a gas permeable packing material, the oxygen absorbent composition containing an linear hydrocarbon polymer having one or more unsaturated groups or a mixture of the polymer with an unsaturated fatty acid compound, an oxidation promoter, a basic substance and an adsorption substance.

  • Process for the production of fine powder
    Patent number: 5250101
    Abstract: A process for the production of a fine powder suitable for use in the fields of electronic materials, catalysts, powder metallurgy, pigments and adsorbens. The powder has a primary particle diameter of not more than 0.5 .mu.m, an average secondary aggregate particle diameter of not more than 10 .mu.m and a secondary aggregate particle specific surface area of 2 to 250 m.sup.2 /g, and is produced by a process comprising heating an organic acid metal salt in the presence of palladium, which lowers the thermal decomposition temperature of the salt, at a temperature elevation rate of 0.5.degree. to 20.degree.C./minute and thermally decomposing the organic acid metal salt in the presence of the palladium in the temperature range of not higher than 400.degree.C.

  • Process for producing copper fine powder
    Patent number: 5094686
    Abstract: A process for producing a copper fine powder, which comprises thermally decomposing anhydrous copper formate in a solid phase in a non-oxidizing atmosphere at a temperature in the range of from 150.degree. to 300.degree. C., thereby yielding a copper fine powder having a primary particle diameter of from 0.2 to 1 .mu.m, a specific surface area of from 5 to 0.5 m.sup.2 /g and small agglomerating properties, said anhydrous copper formate being an anhydrous copper formate powder 90 wt % or more of which undergoes thermal decomposition within a temperature range of from 160.degree. to 200.degree. C. when the anhydrous copper formate powder is heated in a nitrogen or hydrogen gas atmosphere at a heating rate of 3.degree. C./min.
