  • wherein
  • 12) A method of creating a flame retarded 3D-printed object in a layer-by-layer manner, comprising consecutively solidifying thin layers of a UV light curable resin formulation with ultraviolet light, wherein the formulation comprises one or more aliphatic bromine-containing acrylates, optionally followed by post curing. (sumobrain.com)
  • 13) A method according to claim 12, wherein the formulation comprises one or more aliphatic bromine-containing acrylate which is (are) liquid (s) at room temperature. (sumobrain.com)
  • atoms
  • 17) A flame retarded 3D-printed object made of one or more cured polymers, having a structural unit of the formula: incorporated into the polymer chains, characterized in that R comprises bromine atoms that are bound to aliphatic carbons. (sumobrain.com)
  • 2019
  • This market is expected to increase from nearly 3.1 million metric tons in 2014 to 5.6 million metric tons in 2019, at a compound annual growth rate (CAGR) of 12.7% for the five-year period, 2014 to 2019. (gii.co.jp)
  • Reactions
  • In this study, species-specific and/or apparent second order rate constants and mechanisms for the reactions of bromine and chlorine have been determined for various phenolic compounds (phenol, resorcinol, catechol, hydroquinone, phloroglucinol, bisphenol A, p-hydroxybenzoic acid, gallic acid, hesperetin and tannic acid) and flavone. (edu.au)
  • With the data set from this study, the ratio between the species-specific rate constants for the reactions of chlorine versus bromine with phenolic compounds was confirmed to be about 3000.Phenolic compounds react with bromine or chlorine either by oxidation (electron transfer, ET) or electrophilic aromatic substitution (EAS) processes. (edu.au)
  • formation
  • Consistent with its Lewis acidic character, water hydrolizes Al 2 Br 6 with evolution of HBr and formation of Al-OH-Br species. (wikipedia.org)
  • While phenol, p-hydroxybenzoic acid and bisphenol A undergo EAS, hydroquinone, catechol, gallic acid and tannic acid, with hydroxyl substituents in ortho or para positions, react with bromine by ET leading to quantitative formation of the corresponding quinones. (edu.au)
  • study
  • The talk describes a number of classic and recent approaches to study the interactions of membrane-permeabilizing compounds with lipid vesicles. (umich.edu)
  • range
  • The reactivity of bromine with phenolic compounds is very high, with apparent second order rate constants at pH 7 in the range of 104 to 107 M−1 s−1. (edu.au)
  • groups
  • The reactivity of phenolic compounds is enhanced by the activating character of the phenolic substituents, e.g. further hydroxyl groups. (edu.au)
  • claim
  • 4) 3D printable resin formulation according to claim 2 or 3, which is devoid of aromatically-bound bromine acrylates. (sumobrain.com)
  • solid
  • The dimeric form of aluminium tribromide (Al 2 Br 6 ) predominates in the solid state, in solutions in noncoordinating solvents (e.g. (wikipedia.org)
  • main
  • Regarding the tendency of Al 2 Br 6 to dimerize , it is common for heavier main group halides to exist as aggregates larger than implied by their empirical formulae. (wikipedia.org)
