Two organic reactions, namely the reaction of cyclopentadiene (CPD) and dimethyl acetylene dicarboxylate (DMAD) and the dimerization reaction of CPD were conducted in toluene at 298.1 K at atmospheric pressure and measured by in situ FTIR spectroscopy. Band-target entropy minimization (BTEM) analyses were employed for obtaining the pure component spectra of the solutes and their corresponding concentrations. The solute concentrations and the bulk density data were used to evaluate the partial molar volumes of the solute constituents. The partial molar volumes evaluated from this multi-component approach were in good agreement with those determined from independent binary solution measurements. The corresponding volumes of reaction for the CPD + DMAD and dimerization CPD + CPD reactions were determined to be -37 ± 3 cm 3 mol-1 and -31 ± 2 cm3 mol -1, respectively. For completeness, DFT calculations were performed and used to rationalize the vibration modes corresponding to the BTEM spectral estimates as well as to provide predictions of the molar volumes of the solutes. The present study demonstrates the usefulness of a combined spectroscopic, signal processing, bulk density measurement and DFT approach to the determination of partial molar volumes and volumes of reaction directly from the multi-component reactive systems.

Thermolysis of 4-substituted 1,3-bishomocubanones is strongly dependent on the electronic nature of the bridgehead substituent. 4-(N-benzyl)amido- substituted cage compounds 12 unexpectedly furnish bicyclic annelated cyclopentenones 13, whereas the 4-acet

Paragraph 0023; 0121-0126, (2021/07/01)
The invention relates to an application of a hierarchical pore molecular sieve in a the preparation process of cyclopentadiene and JP-10 aviation fuel. The hierarchical pore molecular sieve is one or two or more of an H-ZSM-5 molecular sieve, an H-beta molecular sieve, an H-Y molecular sieve, an H-USY molecular sieve, a La-Y molecular sieve and an H-MOR molecular sieve with a hierarchical pore structure, a sulfonated SBA-15 molecular sieve, a sulfonated MCM-41 molecular sieve, a sulfonated Ti-SBA-15 molecular sieve, a sulfonated MCM-41 molecular sieve, a sulfonated Zr-MCM-41 molecular sieve and a sulfonated Zr-SBA-15 molecular sieve; and the hierarchical pore structure comprises micropores and mesopores. The catalyst and the raw materials used in the method are cheap and easy to obtain, the preparation process is simple, and the hierarchical pore molecular sieve has high activity and selectivity for rearrangement reaction of furfuryl alcohol, hydrogenation reaction of hydroxyl cyclopentenone and dehydration reaction. The invention provides a cheap and efficient synthesis method for synthesizing the JP-10 aviation fuel from a lignocellulose-based platform compound furfuryl alcohol.

Paragraph 0129; 0130; 0132, (2018/06/16)
The invention relates to a method for preparing JP-10 aviation fuel from furfuryl alcohol. The method for preparing JP-10 aviation fuel by taking the furfuryl alcohol as a raw material is totally divided into six reactions as follows: a first reaction of carrying out a rearrangement reaction on a furfuryl alcohol solution in the presence of a base catalyst or under the condition that any catalystis not added to prepare hydroxy cyclopentenone; a second reaction of reacting the hydroxy cyclopentenone and hydrogen under catalysis of a hydrogenation catalyst so as to prepare 1,3-cyclopendiol; a third reaction of dehydrating the 1,3-cyclopendiol to prepare cyclopentadiene; a fourth reaction of carrying out a D-A reaction on the cyclopentadiene to produce dicyclopentadiene; a fifth reaction ofhydrogenating the dicyclopentadiene to produce endo-tetrahydrodicyclotadiene; and a sixth reaction of performing isomerization on the endo-tetrahydrodicyclotadiene to produce hanging type tetrahydrodicyclopentadiene, wherein the prepared hanging type tetrahydrodicyclopentadiene can directly serve as the JP-10 aviation fuel. The invention provides a cheap high-efficiency synthetic method for synthesizing the JP-10 aviation fuel from a lignocelluloses-based platform chemical compound, namely furfuryl alcohol.
