Abstract:
The adsorbent for treating hazardous, gaseous halogen compounds is prepared by (1) impregnating porous active carbon made from coconut shell with a solution containing copper, chromic acid (or 3.5-7.5 wt.% boric acid), silver, ammonium and carbon dioxide, and (2) filtering and drying the impregnated active carbon, successively. Especially as an active component, 1 wt.% pyridine is added to the above solution.
Abstract:
PURPOSE: Provided is a process for producing aromatic carboxylic acid by a liquid phase oxidation of an alkyl aromatic compound, which can maximize yield and prevent explosion. CONSTITUTION: The aromatic carboxylic acid is produced by oxidizing the alkyl aromatic compound and a partially oxidized intermediate thereof by oxygen contained gas in the presence of a cobalt/manganese/bromine catalyst and an acetic acid solvent, wherein metal nickel and carbon dioxide are added to the reaction. The weight ratio of nickel/manganese is 0.01-1 and the oxygen concentration is 2-75%(v/v) based on the total gas and the carbon dioxide concentration is 1-90%(v/v) based on the total gas.

Abstract:
The present invention relates to a method for preparing aromatic carboxylic acid from alkylaromatics by liquid-phase oxidation. More particularly, the present invention relates to a method for preparing aromatic carboxylic acid from alkylaromatics by oxidation in acetic acid as solvent with oxygen-containing gas in the presence of cobalt/manganese/bromine complex catalyst, wherein nickel and carbon dioxide in an appropriate amount are added to increase an activity of cobalt/manganese/bromine complex catalyst. Especially nickel has a synergistic effect with carbon dioxide and maximize the to formation of the desired product having the corresponding carboxylic groups to the number of alkyl groups in a reactant.
Abstract:
PURPOSE: A method for preventing plant disease using Bacillus velezensis G341 strain is provided to ensure strong antagonistic function. CONSTITUTION: A Bacillus velezensis G341 strain(KCTC 11497BP) has antagonistic function. A microorganism formulation for preventing plant diseases contains Bacillus velezensis G341 strain, spore, culture medium of the strain, or extract of the culture medium as an active ingredient. The plant diseases are sheath blight, pyricularia grisea, tomato gray mold, tomato late blight, tomato bacterial wilt, or tomato Fusarium wilt. The culture medium or extract thereof contains Bacillomycin L. fengycin A or subtilisin active substance.
