Abstract
: The objective of this study was to evaluate production and properties of liquefied oil-palm stem adhesive. Method for production of this adhesive was inspired by bio-refinery concept. In this context, vascular bundle of oil-palm stem was liquefied through liquefaction process involving thermo-chemical reaction using chemicals of H 2 SO 4 , phenol, and NaOH at 90 C. Properties of the adhesive were compared to Indonesian Standard for phenol-formaldehyde (PF) resins. Results of the examinations showed color of the liquefied adhesive was brown-blackish, specific gravity was 1.26, solid content was 86%, viscosity was 111 cP, pH was 7.8, gel time was 98 minutes, and free formaldehyde was not detected. Even though the properties of the liquefied adhesive made of vascular bundles’ oil-palm stem were slightly differ from PF resin, application of this adhesive as binder of wood product should be recommended because of its feasibility as the adhesive.
