[3] [4] [5] The ashes of kelp also yield soda ash and were the basis of an enormous 18th-century industry in Scotland. [6] Alkali was also mined from dry lakebeds in Egypt. By the late 18th century these sources were insufficient to meet Europe's burgeoning demand for alkali for soap, textile, and glass industries. [7]
Trona is a common source of soda ash, which is a significant economic commodity because of its applications in manufacturing glass, chemicals, paper, detergents, and textiles. It is used to condition water. It is used to remove sulfur from both flue gases and lignite coals. [19] [20] It is a product of carbon sequestration of flue gases. [21]
Solvay Chemical continued soda ash production through the 20th century. By 1980, the demand for soda ash plummeted. By 1985, the company had lost $55 million over the previous three years, forcing Allied Chemical (AlliedSignal at the time) to close and demolish the plant, dismissing 1,400 employees.
The Leblanc process was an early industrial process for making soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate.
Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates.All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.
Soda ash was used since ancient times in the production of glass, textile, soap, and paper, and the source of the potash had traditionally been wood ashes in Western Europe. By the 18th century, this source was becoming uneconomical due to deforestation, and the French Academy of Sciences offered a prize of 2400 livres for a method to produce ...

Soda ash (sodium carbonate) is the most common agent used to raise the pH and initiate the reaction, and is either added directly to the dye or in a solution of water in which garments are soaked before dyeing. Fiber-reactives dyes are relatively safe and simple to use, [3] and are the same dyes used commercially to color cellulosic fabrics.
