Inhibitor 705 is mainly used to prevent the self polymerization of unsaturated compounds such as olefins, acrylates, and methacrylates during production, storage, and transportation, and to regulate the degree of polymerization in organic synthesis reactions. Its polymerization inhibition performance is superior to traditional inhibitors such as phenols and aromatic amines. ‌
Main application areas:
Olefin monomers: Such as propylene and ethylene, are prevented from self polymerization during the polymerization process. ‌
Acrylic esters/methacrylates: such as hydroxyethyl acrylate and hydroxyethyl methacrylate, widely used in coatings, adhesives, and other fields. ‌
Organic synthesis reaction: When synthesizing pesticides and pharmaceutical intermediates, adjust the polymerization degree of reactants to improve product purity. ‌
Typical application scenarios:
Prohibitor 705 can prevent the self aggregation of unsaturated monomers caused by temperature rise during storage or transportation. ‌
In fine chemical production, Prohibitor 705 can control the rate and degree of polymerization reaction, avoiding the generation of by-products. ‌
In pesticide synthesis, Prohibitor 705 ensures uniform molecular weight distribution of active ingredients and enhances drug efficacy stability. ‌
Add suggestion:
The usual addition amount is 0.1% -0.3%, which can be adjusted according to the reaction system and monomer type.
