Application

                         Pulp and Paper Industry                                                             Textile Industry

                                            Food Industry                                                                      Water Treatment

Reducing Agent: It is widely used as a reducing agent in chemical reactions. For example, in the textile industry, it is used to reduce dyes, helping to improve the dyeing effect and color fastness. In the paper-making industry, it can reduce the lignin in wood pulp, which is beneficial for the bleaching process and improving the quality of paper.

Antioxidant: It can prevent the oxidation of substances. In the food industry, it is used as an antioxidant to prevent the oxidation of food ingredients, thus extending the shelf life of food. For example, it is added to some dried fruits and vegetables to prevent them from turning brown due to oxidation. In the pharmaceutical industry, it is also used to protect some drugs from oxidation and maintain their stability and efficacy.

Bleaching Assistant: In the textile and paper-making industries, it is often used as a bleaching assistant. It can enhance the bleaching effect of hydrogen peroxid e and other bleaching agents, reduce the amount of bleaching agents used, and at the same time, protect the fiber from being damaged by excessive bleaching.

Water Treatment Agent: In water treatment, it can be used to remove dissolved oxygen in water. By reacting with oxygen, it can prevent the corrosion of water-containing equipment and pipelines caused by oxygen, playing a role in protecting the water supply system. It can also be used to treat some industrial wastewater containing heavy metal ions. By reducing the valence of metal ions, the solubility of metal ions is changed, which is conducive to the precipitation and removal of heavy metals.

Chemical Synthesis Intermediate: It is an important intermediate in the synthesis of many organic and inorganic compounds. For example, it is used in the synthesis of sulfonamides, dyes, and other chemicals. It can provide sulfonic acid groups or participate in other chemical reactions to construct the molecular structure of the target product.
