A method of producing crystalline cellulose from a cellulosic material includes the step of reacting the cellulosic material in an aqueous slurry comprising a transition metal catalyst and a hypohalite solution.

A cleaning concentrate dilution system includes a dual chamber system in which a plurality of concentrated formulations are provided, including a first formulation provided in a first chamber and including a hypohalite, and a second formulation provided in a second chamber and including one or more components that are sensitive to concentrated hypohalite, such as certain surfactants and certain fragrances. The system further includes a dispensing container that receives the first and second formulations as well as water to dilute the first and second formulations within the dispensing container.

The present invention relates to a method of preparing an organosulfur compound, and more particularly, to a method of preparing an organosulfur compound including a step of synthesizing an organosulfur compound by reacting specific compounds with a metal hypohalite under a ruthenium catalyst in a mixed solvent containing water and an organic solvent, wherein the metal hypohalite is introduced in a solid state and a portion thereof reacts in an undissolved state. According to the present invention, the present invention has an effect of providing an organosulfur compound preparation method capable of preparing an organosulfur compound in high yield due to excellent reaction stability, short reaction time, and reduced side reactions.

A semiconductor processing liquid comprising a carboxylic acid and a hypohalite ion, wherein the concentration of the carboxylic acid is 0.0001-1.0 mol / L, the hypohalite ion is at least one selected from the group consisting of hypochlorite and hypobromite ions, the concentration of the hypohalite ion is 0.0001-3.0 mol / L, and the pH of the semiconductor processing liquid at 25°C is 7.0-14.0.

Disclosed is an impurity removal and modification method for pyrolysis carbon black of waste tires, the method comprising: dispersing pyrolysis carbon black of waste tires in an alkali solution of potassium ferrate; adding hypohalite; leaving to stand for layering; and performing centrifugation and washing on a lower-layer slurry to obtain a stably dispersed pyrolysis carbon black / water suspension. This modification method can be operated simply and easily; and by means of the method, ash in pyrolysis carbon black of waste tires can be effectively removed, and the pyrolysis carbon black is then stably dispersed in water. In addition, the modification method is low in production cost, and is green and environmentally friendly, and a waste liquid thereof can be recycled.
