The invention relates to enzymatic methods for epoxidation of a non-cyclic aliphatic alken, or a terpen.

A method of producing an epoxy compound, which comprises reacting hydrogen peroxide with a compound having a carbon-carbon double bond, in the presence of at least one of a tungsten compound and a molybdenum compound; and an onium salt comprising 20 or more carbon atoms and one or more of substituents convertible to a functional group containing an active hydrogen or a salt thereof.

There are provided methods and systems for an electrochemical cell including an anode and a cathode where the anode is contacted with a metal ion that converts the metal ion from a lower oxidation state to a higher oxidation state. The metal ion in the higher oxidation state is reacted with hydrogen gas, an unsaturated hydrocarbon, and/or a saturated hydrocarbon to form products.

Epoxidation methods and catalyst are described herein. The epoxidation catalysts generally include a metal component including silver and a support material including kaolinite, wherein the epoxidation catalyst includes less than 55 wt. % metal component.

A method for the production of ethylene oxide wherein the partial pressure of water vapor at the inlet of the reactor is at least about 8 kPa using a high purity carrier comprising alpha-alumina, a promoting amount of at least one Group IA metal, and a promoting amount of rhenium.

The present invention provides methods for the production of terephthalic acid and derivatives thereof using ethylene oxide, carbon monoxide and furan as feedstocks. The process is characterized by high yields and high carbon efficiency. The process can utilize 100% biobased feedstocks (EO via ethanol, CO via biomass gasification, and furan via known processes from cellulosic feedstocks).

A dry fire protection sprinkler in which, when a ratio of a pressure P1 of a pressurized fluid in a flexible tube to a pressure P3 of the fluid in a fluid supply line is less than a predetermined ratio of at least 3 to 1, a differential pressure controller sends a signal to a control valve to open, in order to allow the pressurized fluid in a pressurized fluid source at a pressure of P2 to enter the flexible tube, and, when the ratio of the pressure P1 of the pressurized fluid in the flexible tube to the pressure P3 of the fluid in the fluid supply line equals the predetermined ratio, the differential pressure controller sends a signal to the control valve to close.

Epoxide functionalized polyaromatic feedstocks and processes for their preparation are described. The processes involve functionalizing polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in petroleum or petrochemical streams with epoxide. The epoxide functionalized poly aromatic feedstock can be further treated so as to effect oligomerization or polymerization. The oligomers or polymers may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.
