CHEMICAL ASPECTS OF THE BOOKKEEPER DEACIDIFICATION OF CELLULOSIC MATERIALS: THE INFLUENCE OF SURFACTANTS

摘要

Despite its widespread use in paper deacidification, neither the exact composition of the Bookkeeper reagent nor its time-dependent chemistry are known in sufficient detail. For this reason, our labo- Ratory characterized Bookkeeper reagents by X-ray powder diffraction, micro-infrared spectrometry, energy Dispersive X-ray fluoresence spectrometry and polarized light microscopy. The results clearly show that the Fluorinated dispersants contained in the reagent have a decisive influence on the reaction kinetics and probably Also on the chemical species forming the alkaline reserve.
