This invention is directed to a method for producing ethylene oxide comprising feeding ethylene, high purity oxygen and a ballast gas with a recycle gas in a catalyst filled reactor to form a gaseous mixture; passing the gaseous mixture from the reactor to a recovery unit to selectively separate ethylene oxide and carbon dioxide containing gas; passing at least a portion of the carbon dioxide containing gas to a stripping unit to selectively separate carbon dioxide and a waste gas; passing at least a portion of the waste gas to purge and another portion for recycling as the recycle gas; and recovering ethylene oxide from the recovery unit.

High purity oxygen for ethylene oxide production

The invention is directed to a liquid phase oxidation process, wherein a first oxygen-containing gas is injected into the lower portion of a bubble column reactor vessel containing an oxidizeable organic liquid. A second oxygen-containing gas is further injected into the reactor at a point or points wherein the liquid is substantially depleted in dissolved oxygen prior to said injection. Oxygen from both the first and second oxygen-containing gases is used to oxidize the organic liquid.

Direct oxygen injection into bubble column reactors

A method for producing vinyl acetate using ethylene, acetic acid and argon containing oxygen that maximizes selectivity and minimizes ethylene loses to purge.

Method for producing vinyl acetate

Heterogeneous vapor phase oxidation and other reactions are carried out at the surface of a solid catalyst, with both gaseous reactants and the solid catalyst being dispersed in a recirculating liquid solvent. Reaction and product absorption are combined into a single processing step, with enhanced catalyst performance, and product selectivity and product yields, enhanced mass and heat transfer characteristics and reduced risk of forming explosive mixtures in the course of a particular reaction.

High efficiency heat and mass transfer for vapor phase heterogeneous

Energetic binders, and, more specifically, a class of nitramine-containing polyether polymers characterized by favorable viscosity and glass transition temperature, as well as resistance to hydrolysis are prepared.

An electrostatic method is disclosed for providing multicolor imaging from a single toner bath. The toner bath is a blend of individual toners, each of which contains a color precursor different from the others. Also disclosed is a method for the double encapsulation of toner particles to produce toner particles characterized by multiple encapsulation.

Electrostatic method for multicolor imaging from a single toner bath

An electrostatic multicolor imaging system employs a transfer surface which is charged imagewise such that blended microcapsular chromogenic photohardenable toner particles are electrostatically deposited only in those charged regions of a latent image formed on the surface where colors are to be provided for the image.

Electrostatic system for multicolor imaging using microcapsular

This invention pertains to optical and electrical switching devices and to novel polymers containing pendant organic charge transfer moieties and useful in the fabrication of the switching devices.

Polymer composition containing pendant organic charge transfer salt

A positive or negative latent image can be developed with negatively or positively charged toner particles, respectively, that are microcapsular. The shell material of the toner particles is a melamine-formaldehyde resin or a starch-based material. The core is a liquid solution comprising at least a liquid, ethylenically unsaturated monomer, a leuco dye and a photoinitiator.
