Method of fabricating diol containing bis-cycloaliphate

A method is provided for fabricating a diol containing a bis-cycloaliphate. The diol is hydrogenated with hydrogen and a catalyst. Therein, the diol has a bis-aromatic. The catalyst comprises an active metal and a catalyst carrier. The active metal is a VIII-B-group transition element. The catalyst carrier is an oxide of IV-B-group element. Thus, the diol containing the bis-cycloaliphate is generated.

Trans-Selective and Switchable Arene Hydrogenation of Phenol Derivatives

A trans-selective arene hydrogenation of abundant phenol derivatives catalyzed by a commercially available heterogeneous palladium catalyst is reported. The described method tolerates a variety of functional groups and provides access to a broad scope of trans-configurated cyclohexanols as potential building blocks for life sciences and beyond in a one-step procedure. The transformation is strategically important because arene hydrogenation preferentially delivers the opposite cis-isomers. The diastereoselectivity of the phenol hydrogenation can be switched to the cis-isomers by employing rhodium-based catalysts. Moreover, a protocol for the chemoselective hydrogenation of phenols to cyclohexanones was developed.

Synthesis of jet fuel range high-density polycycloalkanes with polycarbonate waste

Jet fuel range high-density polycycloalkanes were first synthesized with polycarbonate waste by a two-step method which was conducted under mild conditions. In the first step, polycarbonate waste was converted to bisphenol by methanolysis. Subsequently, bisphenol was further converted to polycycloalkanes by hydrodeoxygenation.

Preparation method for hydrogenated bisphenol A and catalyst for hydrogenation of bisphenol A

The invention provides a preparation method for hydrogenated bisphenol A and a catalyst for hydrogenation of bisphenol A. The preparation method comprises hydrogenating bisphenol A at a temperature of 50-100 DEG C, under a hydrogen pressure of 5-10 MPa and at presence of a solvent isopropanol and a ruthenium catalyst, so as to generate hydrogenated bisphenol A, wherein the ruthenium catalyst is a Ru-Zn-Ni/TiO2-CdO catalyst, that is, the ruthenium catalyst takes zinc and nickel as auxiliary active compositions and takes titanium dioxide and cadmium oxide as a composite carrier. The conversion rate of bisphenol A can reach 100%, meanwhile the selectivity of hydrogenated bisphenol A is larger than 97%, and the purity of hydrogenated bisphenol A is 99.5% or more.

METHOD OF CONVEYING LIQUIDS

The present invention relates to a method of continuously conveying a liquid which is used as starting material in a chemical reaction by means of a displacement pump having physically separate forward-transport valves and a liquid-filled bidirectional flow line between displacement pump and forward-transport valves, wherein an auxiliary liquid which is a product or a starting material of the chemical reaction and has a melting point which is below the melting point or below the saturation temperature of the liquid to be conveyed is present in the bidirectional flow line. The present invention additionally provides for the use of a product formed by hydrogenation of an aromatic compound as auxiliary liquid for conveying an aromatic compound and also the use of an alcohol or an ester derived from alcohol and carboxylic acid as auxiliary liquid for conveying carboxylic acids or carboxylic acid derivatives.

Hydrogenation of bisphenol A - Using a mesoporous silica based nano ruthenium catalyst Ru/MCM-41 and water as the solvent

A green approach to the hydrogenation of bisphenol A (BPA) including the selection of catalysts and solvents was demonstrated in this report. The catalyst preparation was also using a simple and green method for synthesizing a silica-supported ruthenium catalyst (Ru/MCM-41) in supercritical carbon dioxide. The characterizations of the Ru/MCM-41 nanocomposites were preformed by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). The nanoparticles have an average size of 3.4 nm which is smaller than the pore size of MCM-41. The hydrogenation of BPA was carried out in a hydrogen pressure of 50 bars and a temperature range from 75 to 85 °C with different catalysts and solvents combinations. It was found that using the synthesized catalyst Ru/MCM-41 in water medium could achieve the highest efficiency and durability for the hydrogenation of BPA.

Efficient and Practical Arene Hydrogenation by Heterogeneous Catalysts under Mild Conditions

An efficient and practical arene hydrogenation procedure based on the use of heterogeneous platinum group catalysts has been developed. Rh/C is the most effective catalyst for the hydrogenation of the aromatic ring, which can be conducted in iPrOH under neutral conditions and at ordinary to medium H 2 pressures (10 atm). A variety of arenes such as alkylbenzenes, benzoic acids, pyridines, furans, are hydrogenated to the corresponding cyclohexyl and heterocyclic compounds in good to excellet yields. The use of Ru/C, less expensive than Rh/C, affords an effective and practical method for the hydrogenation of arenes including phenols. Both catalysts can be reused several times after simple filtration without any significant loss of catalytic activity.
