This technology describes a green and environmental-friendly oxidation process which can be used for bleaching liquids and oils by using low level of hydrogen peroxide. Conventionally, bleaching is conducted at elevated temperature with concentrated hydrogen peroxide or bleach. In this green process, the required amount of hydrogen peroxide is greatly reduced and the process can be conducted under ambient conditions. Moreover, the bleaching process is fully compatible with food and pharmaceutical products as no toxic materials are used in the process. The only end products are oxygen and water.
This technology features a solid promoter which is used to activate hydrogen peroxide to oxidize aromatic or unsaturated compounds with high efficiency and high rate of reaction. This process can be used for bleaching liquids and oils. It can also be used to bleach food and pharmaceutical products either in aqueous solution or organic solvents by using hydrogen peroxide as an oxidant. Colored liquids and oils can be bleached to colourless by using low level of hydrogen peroxide and yield only water and oxygen as final products. This technology is useful for those required to meet certain oil colour specification but wish to enhance bleaching efficiency and minimise hydrogen peroxide usage.
This technology is applicable in the following industries.
Green chemical reactions which use less chemicals and generate environmentally- friendly wastes are becoming more popular in the market, especially in the food and pharmaceutical industries.
