Abstract:
The purpose of the present invention is to provide an advantageous non-barbotage method for oxidation of aromatic hydrocarbons, that, when implemented in various embodiments thereof, provides significantly higher selectivity, a greater level of safety, Sower capital costs, etc., than conventional oxidation processes utilizing the barbotage technique. The essence of the inventive non-barbotage oxidation process is ensuring that the oxidizing agent delivered to the process reactor undergoes continued contact only with exposed surfaces of the liquid phase of the hydrocarbons being oxidized configured as at least one of: formed liquid phase thin film(s), liquid phase continuous stream(s), and/or liquid phase globule (e.g., droplets, etc.) stream(s), preferably, with the surface area(s) of the exposed surface(s) being maximized to increase contact with an oxidizing agent being directed thereto, to ensure that the inventive oxidation reaction occurs at the border between liquid and gas phases, such that the oxidation reaction effectively occurs by way of contact of the oxidizing agent (e.g., oxygen) from the gas phase with exposed surface(s) of the liquid phase of the hydrocarbons being oxidized. The inventive non-barbotage oxidation process may be implemented in a single reactor, or in plural sequential reactors, and may be implemented both in a stand-alone configuration, and in combination with various conventional barbotage methods for oxidation of aromatic hydrocarbons.
Abstract:
The present invention is directed to stabilized peracid compositions. Stabilizing compositions including a metal salt and a chelating agent are added to compositions including peracids. The results stabilized peracid compositions have increased shelf life and storage stability.
Abstract:
This invention relates to a method of curing unsaturated polyester resins or mixtures of such resins and a monomer copolymerizable therewith. More particularly, the invention relates to the curing of such resins and mixtures thereof with a composition comprising acetylacetone peroxide (AAP) in an amount of from about 30 to about 35 percent and a high temperature peroxide. Preferably, the high temperature peroxide is t-butyl peroxybenzoate (TBPB) and is present in an amount of from about 5 to about 10 percent of the composition.
Abstract:
A cross-linking system which includes a 1,2,4-trioxacycloheptane and a crosslink-promoting polyfunctional ethylenically unsaturated compound. This system is employed in a process of cross-linking a thermoplastic polymer. Preferred polymers, useful in this process, include ethylene homopolymers and copolymers.
