Abstract:
     The invention refers to a direct esterifying process in a reactor instead of the conventional constant-boiling dehydrating process for aromatic hydrocarbons of benzene series. Mixed ester is prepd. from the raw ester prod. obtained after neutralization, dehydration and filtration procedures. If the mixed ester is used in a proper proportion for bundling and forming of acetate fiber, the time required for hardening the binder can be shortened.
Time: 15
