Abstract: Process for the preparation of 1,4-naphthodinitrile, by reacting o-phenylene-diacetonitrile with a glyoxalbisaldimine. By this process the 1,4-naphthodinitrile is easily obtained in a one-step process. This compound is an important intermediate for the production of 1,4-naphthalene-dicarboxylic acid.

Abstract: Process for the transformation of comminuted cellulose ether, which has been rendered at least largely water-insoluble by modification but is still highly swellable with water, into an easily workable material, comprising wetting a hydrophilic support web, applying the comminuted modified cellulose ether to the wetted web, and drying. This invention also relates to an apparatus for performing the process.
