摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.

摘要:
Disclosed is a method of preparing an asbestos diaphragm where alkali metal ions are provided from an aqueous alkaline solution within the fibrous asbestos diaphragm, the diaphragm is heated to form an alkali metal silicate layer on the asbestos fibers, and thereafter contacted with anolyte liquor.

摘要:
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.
