What are monomers of bakelite?
phenol and formaldehyde!!!
What is the color of phenol formaldehyde resin after it is prepared?
Phenol formaldehyde resin is typically prepared as a colorless or slightly yellowish liquid. The color can vary depending on the specific formulation and processing conditions used during preparation.
What are the key factors that influence the phenol-formaldehyde reaction?
The key factors that influence the phenol-formaldehyde reaction include the ratio of phenol to formaldehyde, the pH level of the reaction mixture, the temperature of the reaction, and the presence of catalysts or inhibitors. These factors can affect the rate of the reaction, the formation of desired products, and the overall efficiency of the process.
What is the Commercial name of phenol formaldehyde polymer?
Bakelite (plastic) invented by Leo Baekeland.
What is the structure of bakelite?
Bakelite is a thermosetting plastic made from the polymerization of phenol and formaldehyde. The structure consists of a three-dimensional network of cross-linked chains, giving it its rigid and heat-resistant properties.
What were the first plastics made of?
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde
Chemical properties for the Phenol formaldehyde?
Simple phenolic resins are condensation polymers formed from phenol and formaldehyde. Therefore, they contain only the elements found in phenol and formaldehyde: carbon, hydrogen, and oxygen. The characteristic bond for a cured phenolic resin is a methylene group, derived from a formaldehyde molecule, joining two aromatic rings derived from two phenol molecules. A wide variety of structural formulas are possible, because resins can be made from a variety of ratios between phenol and formaldehyde.
What is the difference between phenolic resin and urea formaldehyde resin?
Phenolic resin is made by the reaction between phenol and formaldehyde, whereas urea formaldehyde resin is made by the reaction between urea and formaldehyde. Phenolic resin offers higher heat resistance and better moisture resistance compared to urea formaldehyde resin. Urea formaldehyde resin is typically more cost-effective and has better flexibility than phenolic resin.
What is chemical formula of bakelite?
The chemical name of bakelite is polyoxybenzylmethylenglycolanhydride.
What is chemical content of material for Backalite?
Bakelite is based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907–1909 by Belgian Dr. Leo Baekeland, formed by the reaction under heat and pressure of phenol (a toxic, colourless crystalline solid) and formaldehyde (a simple organic compound).
What kind of adhesives are used in engineered hardwood?
There are many different adhesives used for engineered hardwood. Urea-formaldehyde resins, phenol-formaldehyde resins, melamine-formaldehyde resin, and polyurethane resins are also adhesives used for engineered hardwood.
What are dangers of using phenol formaldehyde resin paint?
Phenol formaldehyde resin paint is a synthetic paint. As the paint cures, it releases toxic gases. Once the paint appears to be dry, the paint continues to releases gases in small amounts for up to six months. This can create health problems.
