Process for manufacturing ethylene oxide using scaled selectivity values

Disclosed herein are methods of using scaled selectivities to assist in determining whether changes to the value of a target ethylene oxide production parameter—such as ethylene oxide production rate—used in the process of epoxidizing ethylene with a high-selectivity catalyst, have caused the process to move away from optimal operation. If... Dow Technology Investments Llc

Hydroformylation process

Catalytic metal loss when using a hydroformylation catalyst comprising an organophosphite ligand is ameliorated by adding CO to a strip gas vaporizer.... Dow Technology Investments Llc

Hydroformylation process

The present invention relates generally to hydroformylation processes. In one embodiment, a process of the present invention comprises: (a) contacting CO, H2, and at least one olefin under hydroformylation conditions sufficient to form at least one aldehyde product in the presence of a hydroformylation catalyst; (b) removing a product-containing liquid... Dow Technology Investments Llc

Reflux condenser

Methods, apparatus, and processes are provided for a condenser including flowing a vapor stream including formaldehyde into a tube bundle in a vertical upflow reflux condenser, where a tube in the tube bundle has a length to outside diameter ratio of greater than about 170:1, flowing a cooling fluid on... Dow Technology Investments Llc

Stabilized organophosphorous compounds

A hydroformylation process wherein the hydrolyzable organophosphorous ligand component of the catalyst is supplied as a stabilized ligand composition comprising a hydrolyzable organophosphorous ligand and, per 100 moles compound, from 0.05 to 13 acid-neutralizing equivalents of an acid scavenger.... Dow Technology Investments Llc

Hydroformylation process

A hydroformylation process wherein a water-soluble amine is contacted with the reaction fluid, liquid from the reactor is sent to an extraction zone, and a neutralized phosphorus acidic compound is at least partially removed from the extraction zone.... Dow Technology Investments Llc

Method of formulating alkylene oxide catalyst in relation to catalyst reference properties

Methods of preparing a second high-efficiency, rhenium-promoted silver catalyst for producing alkylene oxide from an alkylene based on a first catalyst are disclosed and described.
