Catalytic fast pyrolysis (CFP) is an attractive approach to convert biomass to high-quality bio-oil through the deoxygenation of pyrolysis vapors in the form of H2O, CO, and CO2. However, the deoxygenation process comes at the expense of bio-oil yield. This review begins with recent progress on lignocellulosic biomass pyrolysis chemistry and techniques, and then focuses on the latest improvements to the design of advanced catalysts and novel CFP processes. It was found that basic metal oxides (e.g., MgO and CaO) are promising alternative catalysts to zeolites (such as ZSM-5) with respect to the preferred decarboxylation reaction, which merits additional investigation on their structure-function relationships in the future. Additionally, catalytic co-pyrolysis of biomass with waste plastics or waste tires over zeolites is an attractive approach from the viewpoint of preferred dehydration reactions and the high-value utilization of solid wastes. However, the physicochemical properties of the catalysts should be further adjusted. Furthermore, in spite of many interesting results reported in the literature, quantitatively analysis and uniform data presentation format is necessary for the further development of CFP techniques.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 7331-52-4. Reference of 7331-52-4

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 637-64-9, name is Tetrahydrofurfuryl Acetate, introducing its new discovery. Application In Synthesis of Tetrahydrofurfuryl Acetate

Electrochemical fluorination (ECF) of the ester derivatives of oxolane-2-yl-carboxylic acid (1), oxolane-2-yl-methanol (2) and oxane-2-yl-methanol (3) were investigated. Perfluoro(oxolane-2-yl- carbonylfluoride) (4) was obtained from derivatives of 1 and 2, and perfluoro(oxane-2-yl-carbonylfluoride) (5) was obtained from derivatives of 3 as the desired compounds, respectively. From the ECF of acetates of 2 and 3, perfluorospiroethers having a dioxolane ring were also obtained as the cyclization product in low yield together with the desired perfluoroacid fluoride (4 and 5). The structure of these perfluorospiroethers was confirmed by analyzing the chlorinated products, which were obtained by the reaction with AlCl3.

Synthetic Route of 2144-40-3, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.2144-40-3, Name is (cis-Tetrahydrofuran-2,5-diyl)dimethanol, molecular formula is C6H12O3. In a article，once mentioned of 2144-40-3

1,6-Hexanediol (1,6-HDO) was effectively prepared from 5-hydroxymethylfurfural (HMF) over double-layered catalysts of Pd/SiO2 + Ir-ReOx/SiO2 in a fixed-bed reactor. Under optimal reaction conditions (373 K, 7.0 MPa H2, in solvent mixtures of 40% water and 60% tetrahydrofuran (THF)), 57.8% yield of 1,6-HDO was obtained. The double-layered catalysts loaded in double-layered beds showed much superior performance compared to that of a single catalyst of Pd-Ir-ReOx/SiO2, even when the same amount of active components were used in the catalysts. The reaction solvent significantly affected product distributions, giving a volcano-shape plot for the 1,6-HDO yield as a function of the ratio of water to THF. Br°nsted acidic sites were generated on the catalyst in the presence of water which played determining roles in 1,6-HDO formation. A high pressure of H2 contributed to 1,6-HDO formation by depressing the over-hydrogenolysis of reaction intermediates and products to form hexane and hexanol. The reaction route was proposed for HMF conversion to 1,6-HDO on the basis of conditional experiments.

Biocatalytic hydrolysis of 2,3-disubstituted rac-cis- and rac-trans-haloalkyl epoxides 1a-8a using the epoxide hydrolase activity of whole bacterial cells furnished the corresponding vicinal diols 1b-8b as intermediates; these (spontaneously) underwent ring closure to yield cyclic products 1c-6c through an enzyme-triggered cascade reaction. In particular, cis-configured substrates (1a, 3a, 5a, 7a) were transformed in an enantioconvergent fashion, which resulted in the formation of single stereoisomeric products in 100% des and up to 92% ees from the racemates.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 57203-01-7. Synthetic Route of 57203-01-7

We have demonstrated a new application of our oxidizing reagent, a combination of NH2OH·HCl and NaIO4, in the first generalized regioselective 1,2-difunctionalization of olefins. It is a general method for the preparation of beta-iodo-beta?-hydroxy ethers, beta-iodo ethers, beta-iodohydrin, and beta-iodo acetoxy compounds using different reaction media. The reactions are highly regioselective, always affording Markovnikov’s type addition products. The methodology is also applicable for the easy access of terminal acetals. Molecular iodine-free synthesis, room temperature reaction conditions, high yields, use of less expensive reagents, mild reaction conditions, broad applicability of nucleophiles, and applicability for gram-scale synthesis are the notable advantages of this present protocol.
