1.Title
Synthesis of phenolic resin


2.Principle
This experiment illustrates how two simple organic chemicals, phenol and formaldehyde, can be combined to make a polymer whose chemical structure is like a web. Once cured, this
polymer is a giant single molecule whose shape cannot be changed except by breaking bonds between atoms. It can be used to make heat resistant objects like handles for pots and pans, electrical insulator materials, or heat resistant glues. The inventor of this particular polymer was Leo H. Baekeland, working around 1905. In certain formulations it is known as Bakelite. The chemistry of how this happens is complex and you should not try to understand it at this time. The objectives of this experiment are to learn to measure and manipulate chemicals, to control the rate and extent of a chemical reaction by controlling its temperature and reaction time, and to discover how physical and chemical properties of materials may be changed by arranging for suitable reactions to occur. Key reactions are shown below using compact chemical structures.
