摘要:
When a disproportionated chlorosilane is to be produced by causing a starting material chlorosilane liquid to flow through a catalyst-packed layer which is packed with a weakly basic anion exchange resin as a disproportionation reaction catalyst to carry out a disproportionation reaction, before the disproportionation reaction is carried out, the disproportionation reaction catalyst is brought into contact with a processing gas obtained by diluting a chlorosilane with an inert gas to prevent the deterioration of the disproportionation reaction catalyst at the start of the reaction so as to carry out the disproportionation of the chlorosilane efficiently.

摘要:
A medical instrument for transdermally administering a medicine, in which an ionic medicine or an ionic medicine-containing substance is sealed in a bag made of an ion-exchange membrane. The medical instrument for transdermally administering the medicine is favorably used for executing the iontophoresis. By using this medical instrument, an iontophoresis device is realized in a simple structure, inexpensively and in a small size, which is suited for being carried yet making it easy to exchange the ionic medicine.

An iontophoresis device comprising (A) a working electrode assembly having a working electrode, a medicine-containing portion and an ion-exchange membrane, (B) a counter electrode assembly having an electrode which opposes the working electrode, and (C) a power source unit electrically connected to the working electrode assembly and to the counter electrode assembly, enabling an ionic medicine contained in the medicine containing portion to be permeated into a living body by the electrophoresis through the ion-exchange membrane, wherein the ion-exchange membrane has a structure in which voids of a porous film are filled with an ion-exchange resin. The iontophoresis device using the above ion-exchange membrane makes it possible to administer the medicine in amounts larger than those accomplished by using the conventional devices.

摘要:
A method of producing an ion-exchange membrane for iontophoresis by preparing a polymerizable composition containing monomer components and non-polymerizable components which are compatible with the monomer components but do not copolymerize therewith; forming the polymerizable composition into a membrane form; polymerizing the polymerizable composition in the obtained membrane form to thereby form a membrane of a structure in which the non-polymerizable components are dispersed in the polymer having a crosslinked structure; removing the non-polymerizable components from the obtained membrane; and, as required, introducing ion-exchange groups into the polymer. The ion-exchange membrane obtained by the above method is applied to an iontophoresis device. When an ionic medicine contained in a medicine-containing portion of the device is permeated into a living body by the electrophoresis through the ion-exchange membrane, not only ionic medicines having small formula weights but also medicinal ions of formula weights of about 500 to about 1,000 can be efficiently administered into the living body.
摘要:
A laminate consisting of an ion exchange membrane layer comprising a porous film reinforcement and a crosslinked ion exchange resin and a conductive layer formed on at least one side of the ion exchange membrane layer and comprising conductive inorganic particles and a crosslinked ion exchange resin, whereinthe ion exchange membrane layer and the conductive layer are integrated with each other by the above ion exchange resins constituting these layers.This laminate is excellent in dimensional stability, heat resistance and methanol impermeability, which makes it suitable for use in electrochemical devices such as a direct methanol type fuel cell as a membrane-electrode assembly, has high bonding properties between the electrode layer and the ion exchange membrane layer of the membrane-electrode assembly, and provides a fuel cell whose output is not reduced by long-term use.
摘要:
A working electrode assembly for iontophoresis having a working electrode, a medicine-containing portion containing an ionic medicine, and an ion-exchange membrane arranged between the working electrode and the medicine-containing portion, wherein said ion-exchange membrane has both the anion-exchange groups and the cation-exchange groups, and between these anion-exchange groups and cation-exchange groups, the ion-exchange groups of the one side are contained in an excess amount compared to the other ion-exchange groups. The working electrode assembly effectively prevents the contact between the medicine and the working electrode and, at the same time, accomplishes a high efficiency for administering the medicine.
