SPLATS about applied chemistry
The principles of applied chemistry
- The chemical industry is mostly based on just a few simple compounds. Sulfuric acid is probably the most important, with chlorine and caustic soda close behind.
- Only one of the key industrial chemicals, caustic soda, has a simple substitute available, in the form of sodium carbonate, used since ancient Egyptian times.
- In 1723, the use of lead in rum stills was banned by the Massachusetts legislature, after drinkers had complained of stomach problems and partial paralysis.
- In 1783, Nicolas Leblanc developed his Leblanc process to make sodium hydroxide and sodium carbonate from salt, making soap-making possible on a large scale.
- In 1799, Charles Macintosh invented bleaching powder, made when chlorine is absorbed by dry slaked lime. It was patented in the name of Charles Tennant.
- In 1865, the first plastic, parkesine, was made by Alexander Parkes from nitrocellulose, softened by vegetable oils and some camphor (also called xylonite).
- Robert Bunsen analysed igneous rocks from Iceland and Armenia and showed the rocks came from sources which were chemically identical, founding geochemistry.
