  • Patent number: 9573874
    Abstract: Technical grade acrylic acid derived from renewable resources utilizing a base catalyst system by a process including reacting lactide (or lactic acid oligomers) with methyl acetate to form methyl 2-acetoxypropionate in the presence of a base catalyst such as sodium methoxide, pyrolyzing the methyl 2-acetoxypropionate, with or without a catalyst, to methyl acrylate and acetic acid, transesterifying the mixture to acrylic acid and methyl acetate, separating and purifying the acrylic acid by distillation late in the presence of polymerization inhibitor(s). The disclosed process will produce a “green” (i.e. renewable resources derived) acrylic acid and/or methyl acrylate ester.

  • Patent number: 9493391
    Abstract: The present application provides a method for producing an beta-lactone product. The method includes the steps of: reacting an epoxide, a solvent with a carbonylation catalyst and carbon monoxide to produce a reaction stream comprising a beta-lactone then separating a portion of the beta-lactone in the reaction stream from the solvent and carbonylation catalyst to produce: i) a beta-lactone stream with the beta-lactone, and ii) a catalyst recycling stream including the carbonylation catalyst and the high boiling solvent; and adding the catalyst recycling stream to the feed stream.

  • Publication number: 20160102068
    Abstract: Continuous flow systems and methods produce succinic anhydride by a double carbonylation of ethylene oxide with carbon monoxide and at least one catalyst. In some embodiments, the double carbonylation occurs using a single catalyst. In other embodiments, a first catalyst is used to promote the first carbonylation, and a second catalyst different from the first catalyst is used to promote the second carbonylation. The succinic anhydride is isolated from the product stream by crystallization and the catalyst is recycled to the reaction stream.

  • Patent number: 7906679
    Abstract: Materials for making apparatus and a method of inhibiting polymerization during manufacture, purification, handling and storage of subject ethylenically unsaturated monomers are disclosed. In particular, copper or metals containing copper, in the presence of oxygen, have inhibit undesired polymerization resulting in polymer fouling in apparatus used during the manufacture, purification, handling and storage of the monomers, such as acrylic acid, methacrylic acid, acrylic acid esters and methacrylic acid esters. The copper or copper alloys as described herein, in the presence of an oxygen-containing gas, exhibit self-inhibiting surface characteristics when used to make at least a portion of the apparatus to inhibit polymerization of the monomers in contact with the portion of the apparatus including such copper-containing metal.

  • Patent number: 6897255
    Abstract: Novel latex or emulsion compositions containing internally plasticizing and crosslinkable long-chain alkenol ester monomers are disclosed and claimed. Preferred embodiments include latex formed from acrylate or methacrylate esters of long-chain alkenols. A process for the synthesis of the latex composition is also disclosed, which involves (a) esterification of a long-chain alkenol with an ethylenically unsaturated carboxylic acid; (b) polymerization of the ethylenically unsaturated ester in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from ?5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions.
