Production of phenol-formaldehyde resin composites
… the production of industrial laminates based on phenol-formaldehyde resins, with a view of suggesting ways of improving the process economics and/or the physical properties of the final product. Aspects of impregnation, drying, and lamination were investigated. The resins used in all experiments …

Evaluation of Phenol Formaldehyde Resin Cure Rate
… to characterize the cure rate of two commercial phenol-formaldehyde adhesives. Two methods are used, parallel-plate rheometry and dielectric spectroscopy. Viscosity data from a parallel-plate rheometer may be used to track the advance of polymerization as a function of temperature. This data can …

Organic Fillers in Phenol-Formaldehyde Wood Adhesives
… wood composites are typically manufactured using phenol-formaldehyde resols (PF) that are formulated with wheat flour extender and organic filler. Considering that this technology is several decades old, it is surprising to learn that many aspects of the formulation have not been the subject of …

Interaction of phenol-formaldehyde condensates with isoprene rubber
… with the interaction between p-tertiary butyl phenol-formaldehyde condensates and isoprene rubber under conditions resembling those used in industrial vulcanization processes, and involves investigations of reaction rates, mechanisms of reactions and structures produced. The work is an …

Effect of Phenol on the System Quinoline Water
For ten years after the brilliant deduction of the phase rule in 1874 by Willard Gibbs at Yale the work lay buried in the archives of the Connecticut Academy of Science, undisturbed and uninterpreted. It was not until 1884 that Roozeboom of Belgium, who was working on methods of separating salts …

The Microbial Ecology of Phenol Degradation in Activated Sludge.
Phenol. Phenol was discovered in 1834 as a byproduct of the coal gas industry and was first used to deodorize the sewers in England. Subsequently, in 1867, Joseph Lister introduced antiseptic surgery by using 5% phenol to disinfect operating room facilities and wounds (6, 25). Lister’s procedure …

Investigation of the Wood/Phenol-Formaldehyde Adhesive Interphase Morphology
This work addresses the morphology of the wood/ Phenol-Formaldehyde (PF) adhesive interphase using yellow-poplar. In this case, morphology refers to the scale or dimension of adhesive penetration into wood. The objective is to develop methods for revealing ever smaller levels of wood/resin …

The effects of acetone shock loading on phenol acclimated cultures
The possibility of acetone shock loadings to phenol acclimated systems resulting in sequential substrate utilization and increased effluent phenol concentrations was evaluated. Phenol acclimated batch and continuous-flow systems, developed with seed from a municipal wastewater treatment plant, were …

Co-adsorption of phenol and calcium from an industrial wastewater stream
… the removal of problematic pollutants such as phenol and calcium, especially with regards to industrial wastewater streams. The aim of this study was to determine the effectiveness of paper sludge-based biochar as adsorbent for the co-removal of phenol and calcium from the wastewater stream of …

Transalkylation of higher methylphenols with phenol to produce cresols and xylenols
… research was to add value to such C₉˖-polymethylphenol isomer mixtures by converting them into high value cresols and xylenols via transalkylation with phenol over acid zeolite catalysts. This would comprise recovery of the valuable aromatic (phenolic) OH-groups present in the constituents of the …
