Abstract:
    An improved wiped film evaporator (WFE) process for removing low molecular weight species from a hydrocarbyl mixture is disclosed, wherein partial oxidation of a hydrocarbyl mixture precedes the WFE step. Faster rates of distillation are achieved without significant deterioration of hydrocarbyl product properties. Such products can include carbon fiber precursor materials. Similar faster rates are provided by adding higher softening point hydrocarbyl materials with or without prior partial oxidation.
