Ammonium persulfateis an inorganic compound widely useammonium persulfate-2d in chemical experiments and ind

ustry. Its mole=cular formula is (NH4) 2S2O8, which is a white crystalline solid with strong oxidation properties. This compound is mainly prepared by reacting sodium persulfate with ammonia, and the reaction products are crystallized or purified under low temperature conditions.


1. Polymerization reaction

Ammonium persulfate is often used as an initiator in polymerization reactions, promoting monomer polymerization and forming high molecular weight polymers. The triggering effect of ammonium persulfate is mainly achieved through its strong oxidizing properties. The following is a general mechanism of ammonium persulfate in polymerization reactions:

Selection of initiator: The selection of ammonium persulfate as the initiator is usually based on its high oxidation ability. It can release reactive oxygen species and participate in the initiation and expansion process of polymer chains.

Initiation process: Polymerization reactions typically include the initiation stage, expansion stage, and termination stage. In the initial stage, ammonium persulfate decomposes to produce active free radicals, which react with monomer molecules to form primary free radicals.

Polymerization process: Primary free radicals react with other monomer molecules to form longer polymer chains. This process continues during the expansion phase of the aggregation chain, resulting in the formation of larger aggregates.

Termination stage: The polymerization reaction will terminate at a certain moment, which can be achieved through different methods, such as the combination of two free radicals, depletion of reactants, etc. Termination of the reaction leads to the cessation of growth of the polymer chain.

Influencing factors: The efficiency of polymerization reactions and the properties of products are influenced by various factors, including the concentration of ammonium persulfate, reaction temperature, reaction time, and other conditions of the reaction system. The regulation of these factors can control the rate of polymerization reaction and the characteristics of the products.

2. Textile industry

Ammonium persulfate has important applications in the textile industry, mainly reflected in bleaching and printing and dyeing processes. The following are some applications of ammonium peammonium persulfate-4rsulfate in the textile industry:

Bleach: Ammonium persulfate is often used as an oxidant for textile bleaching. In textile production, common raw materials such as cotton, linen, wool, etc. may contain impurities, pigments, or other unclean substances during growth or processing. The oxidizing properties of ammonium persulfate enable it to effectively oxidize and remove these impurities, thereby improving the cleanliness and whiteness of textiles.

Printing and dyeing process: Ammonium persulfate is also widely used in the printing and dyeing process of textiles. In dyeing and printing, ammonium persulfate acts as an oxidant to participate in the reaction, helping the dye bind to the fibers, ensuring uniform and long-lasting color. Its properties as an oxidant make it an effective auxiliary in the field of printing and dyeing.

Reaction condition control: When using ammonium persulfate in the textile industry, it is necessary to carefully control the reaction conditions, including temperature, pH value, etc. This helps to ensure the effectiveness of oxidation reactions and the quality of textiles. At the same time, the amount of ammonium persulfate used should also be reasonably controlled to avoid possible side reactions and excessive oxidation.
