In the complex world of chemical synthesis and polymer production, controlling reactive intermediates is key to ensuring safety, efficiency, and product quality. Among the most critical challenges is preventing the premature polymerization of monomers, the basic units that form long polymer chains. Inhibitor 701, scientifically identified as 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy (CAS 2226-96-2), has emerged as a highly effective solution for this purpose. As a leading manufacturer and supplier of specialty chemicals in China, we provide deep insights into this vital compound.

Understanding Inhibitor 701 (4-Hydroxy-TEMPO):

Inhibitor 701 belongs to the class of stable nitroxide free radicals. Its molecular structure, C9H18NO2, contributes to its remarkable ability to scavenge free radicals, which are the primary initiators of polymerization. Unlike many conventional inhibitors, Inhibitor 701 exhibits excellent performance even under oxygen-deficient conditions, making it a versatile choice for a wide range of industrial applications. Its effectiveness is notably superior to older inhibitors such as phenols, aromatic amines, and quinones.

Key Chemical Properties and Advantages:

  • High Purity: We supply Inhibitor 701 with a minimum purity of 99%, ensuring optimal performance and consistency in your processes.
  • Excellent Solubility: It is soluble in common organic solvents like ethanol and benzene, as well as in water. This dual solubility profile offers significant advantages in formulating and applying the inhibitor across different systems.
  • Stability: While stable under recommended storage conditions (cool and dry), it is incompatible with strong oxidizing agents, a common consideration for all chemical handling.
  • Broad Applicability: Inhibitor 701 effectively prevents the self-polymerization of monomers such as acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, and butadiene.

Applications in Monomer Handling:

The primary application of Inhibitor 701 is in stabilizing monomers during critical stages:

  • Production & Purification: Prevents unwanted polymer formation during synthesis and separation processes.
  • Storage & Transportation: Ensures monomers remain stable and safe for extended periods, mitigating risks of thermal runaway and product degradation.
  • Organic Synthesis: Assists in controlling the degree of polymerization for olefins and their derivatives.
