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.
Phenol has many many uses.
It's a benzene ring with a -OH (hydroxyl) group attached directly to it. Making it more reactive than the very stable benzene.
It was used as an early type of antiseptic.
Now you can react phenol with many other chemicals and create alkyl phenols found in detergents, chlorophenols found in antiseptics.
Also phenol is found in aspirin and paints.
All phenols are common to having an -OH group attached to a benzene molecule. In pure form phenols are water soluble organic crystals. They are also dangerous skin blistering agents.
phenol is used to produce salicylate, which in turn is used for the production of aspirin and similar pharmaceuticals

Bakelite is a thermosetting plastic. Its structure is made up of extensively cross-linked chains, which stop the chains from unfolding.
Most Dangerous Household Chemicals. Fresheners include formaldehyde a highly toxic known carcinogen and phenol which can cause hives, convulsions. Chemical Warning Labels. Wow who would have thought.
Yes. Formaldehyde is a chemical compound, which is a pure substance, and pure substances, in addition to solutions, are homogeneous.
HCHO is the chemical formula of formaldehyde.
it's a base
The chemical name of bakelite is polyoxybenzylmethylenglycolanhydride.
Phenol Formaldehyde Resin in liquid phase appear as rides brown.
Phenolic resins are made from chemicals of the phenol group while urea formaldehyde resin are made from urea and formaldehyde. These two resins have different properties.
phenol and formaldehyde!!!
low viscosity phenol formaldehyde resin will coated for polyester pre-sizing.

Bakelite is a thermosetting plastic. Its structure is made up of extensively cross-linked chains, which stop the chains from unfolding.
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).
Bakelite (plastic) invented by Leo Baekeland.
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde

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.
