    Dioctyl Phthalate


    Technical Specifications: Specifications Industrial Grade Food Grade
    General Description and applications:Phthalates are by far the most widely used plasticisers, primarily to make soft and flexible polyvinyl chloride (PVC) for the applications in the industry of automotive, building & construction material, cable, flooring, medical device and toys. Phthalates make the long polyvinyl molecules to slide against one another. Minor quantity of phthalates is used in adhesives, caulk, sealants, and paint to improve work performance. Small molecule phthalates are used as solvents in perfumes to provide longer linger longer and in nail polish to prevent chipping. They are also used as ingredients of insect repellents, as solvents in lacquer and pesticides, and as dye carrier. They are used as textile lubricating agents and as solid rocket propellents. Phthalates are produced by the reaction of phthalic anhydride with appropriate alcohols from methanol up to isodecanol (C13), either as a straight chain or with some branched in the presence of concentrated sulphuric acid as a catalyst. Excess alcohols are recovered and recycled and phthalates are purified by vacuum distillation and/or activated charcoal. A wide range of phthalates of varying chain length and structure provides each adequate properties and cost-effective for various processing and mechanical requirements. C8 - C9 phthalates, such as di-2-ethyl hexyl phthalate (DEHP or called DOP), diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP) are the most widely used general purpose phthalates. DOP is the dominant plasticizer used in PVC, providing low cost. Short chain phthalates (C3 - C7) are used when rapid setting and stain resistance is required. 2-Ethyl hexanol, produced by the dimerisation of butyraldehyde obtained from propylene, is cheaper than isononyl alcohol which are prepared by the carbonylation of an olefin. Long chain phthalates (C11 - C13) are used when high temperature stability is required. C1 and C2 phthalates are used as solvents. Special phthalates which contain aromatic ring in the side chain are used when fast-fused is required. Diallyl phthalate is used as a crosslinking agent, plasticizer or dying carrier for polyesters.

    DOP (Di-sec-Octylphthalate) is the most widely used general purpose plasticizer for the manufacture of flexible plastics (especially with PVC). It is insoluble in water and has a good stability to heat and ultraviolet light, a broad range of compatibility, and excellent resistance to hydrolysis.It is used in PVC, polyvinyl acetate, rubbers, cellulose plastics and polyurethane. End application include PVC floorings and wall coverings, expanded leather, PVC foams, films, sealing and adhesive systems based on polyurethane or polysulphide, PVAc based adhesives and paint binders€‚
