What are Phenol and Formaldehyde?
Phenol is a colorless, crystalline solid with a sweet, burning taste. It is soluble in water, alcohol, and ether. Phenol is used to make plastics, drugs, and other chemicals.
Formaldehyde is a colorless, flammable gas with a pungent, irritating odor. It is used to make plastics, drugs, and other chemicals.
What is Phenol Formaldehyde Resin?
Phenol formaldehyde resin is a synthetic resin formed from phenol and formaldehyde. It is a thermosetting resin, meaning that it cures (hardens) when it is heated and forms a permanent bond. It is used in a variety of applications, including adhesives, coatings, and composite materials.
Phenol-Formaldehyde Resin Structure
Phenol formaldehyde resin is a thermosetting plastic that is made from phenol and formaldehyde. The resin is formed when the two molecules react and link together to form a long chain. The resin is then used to make products such as particleboard, plywood, and fiberboard.
Phenol-Formaldehyde Resin Properties
Phenol formaldehyde resin is a synthetic resin made from phenol and formaldehyde. It is a thermoset plastic that is used to make products such as adhesives, coatings, and molded products.
Some of the key properties of the phenol-formaldehyde resin include:
– High strength
– Resistance to chemicals and solvents
– Low flammability
– Good thermal stability
How Phenol-Formaldehyde Resins are Produced?
Phenol formaldehyde resins are produced by the reaction of phenol and formaldehyde in the presence of a catalyst. The most common catalyst is zinc chloride.
Phenol-Formaldehyde Resin Preparation
A) Phenol (1.5 mol) is placed in a 3-necked flask equipped with a stirrer, condenser, and thermometer.
B) The flask is cooled in an ice bath and then 0.5 mol of formaldehyde is added dropwise.
C) The reaction mixture is stirred at room temperature for 16 hours.
D) The resin is then filtered and washed with cold water.
Phenol-Formaldehyde Resin Applications
The phenol-formaldehyde resin is used in a variety of applications, including the following:
Adhesives and sealants
Composite materials
Paints and coatings
Printing inks
Wood composites
