Ceylon Cold Stores was established in 1866 as the Colombo Ice Company, which in 1863 imported the country's first ice-making machine.With an initial capital of £1,600, two steam engines of 8 and 9 horsepower, and a total of 22 employees, the company started producing ice on a commercial scale. [3]
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
The diaphragm prevents the reaction of the caustic soda with the chlorine. A diluted caustic brine leaves the cell. The caustic soda must usually be concentrated to 50% and the salt removed. This is done using an evaporative process with about three tonnes of steam per tonne of caustic soda. The salt separated from the caustic brine can be used ...
To a technical name: This is a redirect from a common term to a more technical name.
Pears soap was made using a process entirely different from other soaps. A mixture of tallow and other fats was saponified by an alkali.This is currently caustic soda (sodium hydroxide) since the ingredients list shows sodium salts of fatty acids, but a chemist reports that in the 1960s, caustic potash (potassium hydroxide) was used.
The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3). The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [ 1 ]
The joint venture plant, named GNAL, will have a capacity of 266,667 MTPA caustic soda plant along with a 130 MW CPP at Dahej. [6] [7] The equity holding of GACL and NALCO for the GNAL is in the ratio of 60:40. [8] NALCO will purchase a minimum of 50,000 MTPA caustic soda from GNAL for its aluminium refineries. [9]
This is because wool is soluble in caustic soda solutions. Instead, it is possible to dye wool at room temperatures with indigo (vat blue 1) and other low substantive vat dyes using soda ash as the alkali source with very little strength loss. Vat red 10, vat violet 13 and vat orange 1 can be applied in this manner as well. [2]
