Discovering Fibres: Cellulose Products

Humans have been extracting and using fibres from plants for many thousands of years but once the pioneering chemists of the 19th Century starting investigating, new products were derived from cellulose. The first were plastics.

The History of Plastics

Introduction to Plastics - from IPS Flow Systems(pdf 35.9kB)

One reason to develop a plastic was the need for billiard balls, because the world was running out of elephant ivory which was used then to make the balls. J. W. Hyatt further developed the product Parkesine, cellulose nitrate, as a replacement. The product was called Celluloid. The most common uses of Celluloid today are for table tennis balls and guitar picks. In the 1920’s and 30’s celluloid was used for the side windows of cars. After a few years they lost their transparency and had to be replaced.

Because the plastic did not last well and could explode if overheated, these days billiard balls are made of synthetic resins such as Bakelite.

Another use of Celluloid was as the base for movie films but once again, the films deteriorated and caught fire easily if they jammed in the projector, so safer films were invented after a few cinemas burnt down.

What is cellulose?

Cellulose is made by chloroplasts in plant cells from carbon dioxide, water and sunshine.

Simple sugar molecules (monomers) made of carbon, hydrogen and oxygen atoms are linked together in various ways to make starch chains and even longer chains, up to 10 0000 monomers, to make the cellulose. Because there are many joined monomers, the molecules are called polymers. Because they are made by living organisms they are called biopolymers; other biopolymers are proteins and DNA.

Biopolymers can be broken down by fungi and bacteria. They can be renewed by growing more plants . They store carbon and carbon dioxide so they are good for the atmosphere. They can be put in a household compost bin for recycling.

Cellulose extraction from wood (KJA-1) - laboratory procedure to remove lignin, wood is converted into fine slivers, treated with a solvent eg acetone to remove lipids and resins and then heated under reflux with dioxane and acid mixture to remove lignin followed by neutralization with an alkaline solution eg sodium hydrogen carbonate. Students could draw a flow diagram from this information.(pdf 31.1kB)
