Web8 apr. 2024 · Properties of Phenol in Detail 1. Boiling Point of Phenol Phenols usually have a higher boiling point when compared to the other hydrocarbons that have equal molecular masses. This is because of the presence of the intermolecular hydrogen bonding between the hydroxyl groups of the phenol molecules. Web24 feb. 2024 · Phenol has the higher boiling point about 181.7 °C, because in phenol the -Oh group is attached to an unsaturated carbon atom due to which it forms stronger hydrogen bonding than the alcohols and so phenol is more soluble in water and need more energy to break the H-bonds which increases its boiling point.

WebPhenol, with the chemical formula C H O H 6 5, is a white solid that has a smell similar to that of a disinfectant. Care must be taken when handling solid phenol as it can be corrosive to the skin. The melting point of phenol ( ∼ 4 0. 5) ∘ C is much higher than those of benzene and methylbenzene (toluene). Phenolic resins are found in myriad industrial products. Phenolic laminates are made by impregnating one or more layers of a base material such as paper, fiberglass, or cotton with phenolic resin and laminating the resin-saturated base material under heat and pressure. The resin fully polymerizes (cures) during this process forming the thermoset polymer matrix. The base material choice depends on the intended application of the finished product.
