  • Patent number: 11845068
    Abstract: The present invention relates to the use of n-butyllithium for catalyzing the hydroboration of an imine and a borane. A catalyst, the borane and the imine are sequentially stirred and mixed uniformly, and are reacted for 1-2 h; the mixture is exposed to air to terminate the reaction; and the reaction liquid is subjected to reduced pressure to remove the solvent, so as to obtain a borate with different substituents. The n-butyllithium disclosed in the present invention can be used for catalyzing the hydroboration of the imine and the borane in high activity under room temperature conditions, the amount of the catalyst is only 4-5 mol % of the molar weight of the imine, and the yield of the reaction can reach 90% or more.

  • Patent number: 11781077
    Abstract: Described is a novel process for disaggregating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction (HAF), fermentable pyrolytic sugars and phenolics based products in a highly economical and energy efficient manner. Phase separation of the esterified pyrolysis oil after an oxidative pre-treatment and the quantitative recovery of the separate fractions is described. Phase separation uses batch as well as continuous reactor systems. The resulting HAF is an energy dense, thermally stable, water free, non-corrosive to carbon steel, and is a free flowing liquid suitable for combustion and for upgrading to transportation fuels. Pyrolytic sugars which are mainly anhydrosugars can be further converted by fermentation to ethanol or other products. Monomeric phenols are useful industrial intermediates and the organic acids in the original pyrolysis oil are mainly recovered as esters of the separation solvents.
