  • Publication number: 20100056681
    Abstract: Triglyceride PVC plasticizers can be produced by recovery of C5 to C10 aldehydes having low average levels of branching from a hydroformylation product, oxidizing the aldehydes with oxygen and/or air to form an acid, recovery of the resulting acid, and esterification with glycerol. Plasticizer compositions including such products or linear triglycerides combined with a secondary plasticizer and articles made therefrom are disclosed.

  • Publication number: 20100048778
    Abstract: C9 to C11 alkyl benzoates are used as plasticisers for polyvinyl chloride in particular in combination with plasticisers such as di-2-ethyl hexyl phthalate, diisononyl phthalate, di-2-propyl heptyl phthalate, diisodecyl phthalate or di-2-ethyl hexyl terephthalate. The use of the C9 to C11 alkyl benzoates provides low viscosity low volatility plasticisers, which are fast fusing with lower hot bench gelation temperature and which can be used to reduce the staining problems associated with use of di-2-ethyl hexyl phthalate and diisononyl phthalate. The low viscosity of the C9 to C11 alkyl benzoates allows the formulation of solvent free flexible PVC formulations meeting stringent VOC limitations.

  • Patent number: 7667080
    Abstract: Mixtures of C8-10 primary alcohols, preferably C9 alcohol rich, comprise from 15 to 70 wt. % unbranched molecules, the balance being branched molecules having an average branchiness of at most 2.00 branches per molecule, at least 80% of the ranches being methyl branches and at least 50% of the branched molecules being mono-methyl branched. Plasticiser esters and surfactant derivatives derived from these alcohol mixtures are also provided. The alcohol mixtures are preferably produced by hydroformylation of octene rich streams formed by Fischer-Tropsch synthesis.

  • Publication number: 20080275267
    Abstract: Esters produced by the catalyzed reaction of alcohols and acids or anhydrides are neutralized by treatment with an aqueous alkaline alkali metal salt solution in an amount that provides less than a stoichiometric amount of alkali metal salt in relation to the acidity of the crude ester and the amount of water present during the treatment is from 0.8 to 1.4 wt % of water based on the weight of crude ester. When using titanium as the esterification catalyst, the ester resulting from this process contains less than 0.01 ppm by weight of titanium residue, so that it is storage stable when stored in the presence of an antioxidant.
