  • Publication number: 20190367647
    Abstract: The invention discloses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers containing dicyclopentadiene, a method of producing the same and use thereof. The cured products of the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention exhibit low dielectric constant, low dissipation, and high glass transition temperature. As the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention have number-average molecular weight ranging from 2500 to 6000 g/mol, the substrate made of theses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers can pass the pressure cook test. Besides, the low dissipation factor characteristic the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention can only be demonstrated at number-average molecular weight higher than 2500 g/mol.

  • Patent number: 9714202
    Abstract: A method for producing adamantane includes the steps of preparing a catalytic composition including an acidic ionic liquid and a co-catalyst and subjecting a tetrahydrodicyclopentadiene-containing component to isomerization in the presence of the catalytic composition to form adamantane. The acidic ionic liquid includes aluminum chloride and a quaternary onium compound selected from the group consisting of a quaternary ammonium halide, a quaternary phosphonium halide, and a combination thereof. The co-catalyst is an oxygen-containing reagent.

  • Patent number: 9586886
    Abstract: Fatty acids are produced through transacylation. An organic nitrogen-containing compound is reacted with alkyl sultone to generate a white solid of a zwitterionic compound. After being purified and dried, the white solid is powdered to be reacted with a Bronsted strong acid for obtaining a clear viscous water-based acidic ionic liquid (IL) as a catalyst used used to effectively process transacylation between oil and acetic acid (HOAc) for fabricating fatty acid (FFA) and glycerol triacetate (GTA). Therein, unsaturated fatty acid is simultaneously processed through addition acetoxylation to obtain stabilized acetoxy fatty acid (AFFA). After, HOAc is recycled through vacuuming. Then, the product and the IL are stratified. The product at upper layer is taken out. The IL at lower layer can be recycled for processing transacylation and addition acetoxylation repeatedly. Therein, fatty acids including the stabilized AFFA are obtained from the product after taking out GTA through vacuum distillation.
