Process for the preparation of nitrocellulose solutions having a low water content
Abstract:
The present invention relates to the continuous preparation of alcohol- and plasticizer-free finished nitrocellulose solutions having a particularly low water content by partial distillative falling-film evaporation of comparatively water-rich, optionally emulsion-like crude nitrocellulose solutions which are preferably provided by dissolving nitrocelluloses of the customary solid forms offered, which are known to be initially water-moist as a result of the preparation, in preferably ethyl acetate.
