An active agent delivery device comprises (a) microporous material comprising a matrix consisting essentially of linear ultrahigh molecular weight polyolefin, a large proportion of finely divided water-insoluble filler of which at least about 50 percent by weight is siliceous, and interconnecting pores; and (b) a releasable active agent or precursor thereof associated with at least a portion of the filler.

Active agent delivery device

Discloses electro-organic synthesis process using a water wetted gaseous feed. Also discloses the electro-organic synthesis of hydrogen peroxide; 1,4-naphthoquinone; and organic nitriles.

Electro organic method

Disclosed is the preparation of electrodes provided by depositing hydrophilic electrolyte resistant resin atop an electrocatalyst on a metallic substrate and treating the resin to cause it to flow whereby to obtain a firmly bonded assembly of resin, electrocatalyst and metallic substrate.

Permionic membrane electrolytic cell

Discloses the electro-organic oxidation of saturated hydrocarbons to yield alcohols glycols, aldehydes, acids, carbonates and alkylene oxides.

Electro organic method and apparatus for carrying out same

Discloses the electro-organic synthesis of carboxylic acids utilizing gaseous CO.sub.2 in a solid electrolyte electrolytic cell.

Gaseous organic compounds are reacted at the surface of the electrode in a cell having a solid polymer electrolyte and externally applied current. The improvement passes water vapor to the solid polymer electrolyte to maintain the water of hydration in the solid polymer electrolyte.

Disclosed is a solid polymer electrolyte unit, an electrolytic cell containing the unit, and an electrolytic process utilizing the unit. The solid polymer electrolyte unit has anodic and cathodic means contacting opposite surfaces thereof, and is characterized by the structure of the cathode. The cathode removably and compressively bears upon the permionic membrane, and is a microporous, metallic cathode.

Cathode element for solid polymer electrolyte

Disclosed is a zero gap permionic membrane electrolytic cell where at least one electrode has hydrophilic resin bonded to the electrocatalyst and interposed between the electrocatalyst and the permionic membrane. This excludes electrolyte therefrom, reduces the likelihood of perforation of the permionic membrane, and provides enhanced electrical contact.

Disclosed is a solid polymer electrolyte having anode means in contact with the anodic portion thereof, and cathode means in contact with the cathodic portion thereof. The anodic portion has higher cation selectivity than the cathodic portion, whereby to prevent migration to the anolyte of hydroxyl ion evolved in or on the membrane. Also disclosed are an electrolytic cell containing the solid polymer electrolyte, and an electrolytic process utilizing the solid polymer electrolyte.

Solid polymer electrolyte cell

Discloses the electrolysis of aqueous alkali metal halides while maintaining the anolyte compartment at an elevated pressure, whereby to recover chlorine therefrom at a superatmospheric partial pressure. The superatmospheric partial pressure chlorine gas is recovered from the cell and condensed.

Electrolytic process including recovery and condensation of high

Disclosed is a method of cathode-diaphragm where the cathode is coated with a protective film, and thereafter a diaphragm is deposited thereon.

Method of preparing a cathode-diaphragm unit

Process for electrolyzing an alkali metal halide

Disclosed is a solid polymer electrolyte having anode means in contact with the anodic portion thereof, and cathode means in contact with the cathodic portion thereof. The anodic portion has higher cation selectivity than the cathodic portion, whereby to prevent migration to the anolyte of hydroxyl ion envolved in or on the membrane. Also disclosed are an electrolytic cell containing the solid polymer electrolyte, and an electrolytic process utilizing the solid polymer electrolyte.
