-
Paragraph 0094-0097; 0100-0104, (2021/05/29)
The invention belongs to the technical field of medicines, and discloses an aromatic compound hydrogenation and hydrodeoxygenation method under mild conditions and application of the method in hydrogenation and hydrodeoxygenation reactions of the aromatic compounds and related mixtures. Specifically, the method comprises the following steps: contacting the aromatic compound or a mixture containing the aromatic compound with a catalyst and hydrogen with proper pressure in a solvent under a proper temperature condition, and reacting the hydrogen, the solvent and the aromatic compound under the action of the catalyst to obtain a corresponding hydrogenation product or/and a hydrodeoxygenation product without an oxygen-containing substituent group. The invention also discloses specific implementation conditions of the method and an aromatic compound structure type applicable to the method. The hydrogenation and hydrodeoxygenation reaction method used in the invention has the advantages of mild reaction conditions, high hydrodeoxygenation efficiency, wide substrate applicability, convenient post-treatment, and good laboratory and industrial application prospects.

Paragraph 0041-0051, (2018/03/24)
The invention discloses a production method of a tertiary butyl cylcohexyl ethyl carbonate synthetic perfume and relates to the technical field of fine chemical production. The production method provided by the invention comprises the following steps of by taking phenol and tert-butyl alcohol as starting materials to perform alkylation reaction, then performing hydrogenation on a reactant, and performing acetylation reaction on the reactant and diethyl carbonate to produce tertiary butyl cylcohexyl ethyl carbonate, wherein the raw materials are available, the yield is high, the proportion of o-tert butylphenol produced by reaction of the phenol and the tert-butyl alcohol and p-tert-butylphenol reaches 7 to 3, an iris ester product can be obtained after performing hydrogenation and esterification on the p-tert-butylphenol as a by-product and is put to use. The production method is strong in controllability of technological parameters, good in repeatability and simplified in operation; and a product is high in purity, pure and gentle in fragrance and accords with the flavor blending requirements for an essence perfume.

Fast pyrolysis of biomass for bio-oil production is a direct route to renewable liquid fuels, but raw bio-oil must be upgraded in order to remove easily polymerized compounds (such as phenols and furfurals). Herein, a synthesis strategy for graphene encapsulated Ru nanoparticles (NPs) on carbon sheets (denoted as Ru@G-CS) and their excellent performance for the upgrading of raw bio-oil were reported. Ru@G-CS composites were prepared via the direct pyrolysis of mixed glucose, melamine and RuCl3 at varied temperatures (500-800 °C). Characterization indicated that very fine Ru NPs (2.5 ± 1.0 nm) that were encapsulated within 1-2 layered N-doped graphene were fabricated on N-doped carbon sheets (CS) in Ru@G-CS-700 (pyrolysis at 700 °C). And the Ru@G-CS-700 composite was highly active and stable for hydrogenation of unstable components in bio-oil (31 samples including phenols, furfurals and aromatics) even in aqueous media under mild conditions. This work provides a new protocol to the utilization of biomass, especially for the upgrading of bio-oil.
