dc.description.abstractThis study was aimed to compare pulp properties of Pinus pinea heartwood and sapwood pulp obtained frommodified soda method and to investigate effects of potassium borohydride (KBH4) used as a protective agent incooking processes. Eight different cooking experiments were applied to the heartwood and sapwood samples bychanging KBH4 ratio. The effects of KBH4 on some chemical, physical and optical properties of pulps obtainedfrom cooking processes were determined. Due to high content of soluble extraction of heartwood, yield ofheartwood pulp was approximately 24% lower than that of sapwood pulp. Using KBH4 in pulping processesincreased sapwood pulp yield, while it has a decreasing impact on heartwood pulp yield. Kappa number andviscosity values of sapwood pulps were better than those of heartwood pulps. With addition of KBH4 to liquorthere was increased kappa numbers of sapwood pulp in contrast to heartwood. In generally, physical properties ofsapwood pulp are better than that of heartwood pulp. But, there are no significant difference in optical propertiesbetween heartwood and sapwood pulp. With no regard to the type of pulps used, the pulp optical properties wereimproved by using KBH4 in pulping processes.en_US
