dioxide, sodium hypochlorite, hydrogen peroxide, and oxygen. Between bleaching treatments, a strong alkali (usually sodium hydroxide) is used to extract the dissolved lignin from the surface of the fibers. The bleaching agents and the sequence in which they are used depend on a number of factors, such as the

The most famous procedure, known as the Kraft process, involves cooking wood chips in an alkaline solution of sodium sulfide and sodium hydroxide: the nucleophilic ...
Caustic soda, also known as sodium hydroxide (NaOH), is a versatile chemical compound that is widely used in various industries, including papermaking. It is a highly corrosive and reactive substance that can cause severe burns and other health hazards if not handled properly.
Caustic Soda in the Kraft process or Sodium Hydroxide in soda pulping are used to break the lignin bonds of wood being processed into pulp for papermaking. Using recycled chemicals as makeup from other sources (spent caustics) aids in the reduction of the environmental impact of chemical pulping.
In the paper recycling process, sodium hydroxide is used to separate the ink from the paper fibers allowing the paper fibers to be reused again. Sodium hydroxide is also used to refine raw materials for wood products such as cabinets and furniture and in wood bleaching and cleaning.
Sodium Hydroxide, a strong alkali is used to extract the dissolved lignin from fibers surface. The bleaching agents and the sequence in which they are used depend on a number of factors, such as the relative cost of the bleaching chemicals, type and condition of the pulp.
