Chemical Properties Of Dioctyl Maleate CAS 2915-53-9

  1. Dioctyl maleate (MF: C20H36O4, MW: 340.5) is produced by the esterification of maleic acid (cis-butenedioic acid) with octanol. It is a colourless, transparent liquid containing ester groups and carbon-carbon double bonds, exhibiting moderate reactivity and capable of participating in copolymerisation and addition reactions (e.g., copolymerisation with monomers such as vinyl chloride and styrene). .
    Dioctyl maleate (DOM) is an important ester compound. It is commonly used in plastic additives, fragrance synthesis, and other fields.

Product Application Of Dioctyl Maleate CAS 2915-53-9

  1. As an internal plasticiser, Dioctyl Maleate can be copolymerised with monomers such as vinyl chloride, vinyl acetate, styrene, and acrylic esters to produce films, pipes, sheets, and other products.
  2. As a resin modifier, it enhances the impact strength and crack resistance of certain resins (e.g., polyvinyl chloride), thereby extending the service life of products.
  3. Used in the synthesis of sodium dioktyl succinate sulfonate (rapid penetrant T), widely applied in the textile, dyeing, and leather industries.
  4. DOM can undergo polymerisation reactions on its own or copolymerise with other monomers to form high-molecular-weight polymers, which are used to prepare adhesives, coatings, etc.
  5. DOM also has certain applications in the pharmaceutical industry, serving as an intermediate in drug synthesis or an auxiliary component in drug formulations.
  6. 2-Butenedioic acid dioctyl ester participates in the synthesis of certain fragrance compounds and can be used to prepare compounds with special fragrances.
  7. Dioctyl maleate can also be used as an additive for lubricants or fuels, an elastic paper treatment agent, and a raw material for aspartic polyurethane resins.
