Ceresin

Ceresin is a waxy resin product. It is used as a substitute for beeswax, inter alia, for wax candles.

Ceresin (also ceresin, Cerosin, Cerin, earth wax, mineral wax, Ozocerotin or artificial wax called ) is produced by heating with the addition of 6 to 10% sulfuric acid from ozokerite - an organic mineral that is extracted in mining and mainly consists of hydrocarbons.

For decolorization, the ceresin is treated with charcoal and so gives a pale yellow color. For complete decolorization sulfuric acid and sodium hydroxide is used. A little less rich acid-free production is possible using a lot of coal, followed by extraction with benzene or carbon disulphide, filtering and distilling off the solvent. The resulting pure ceresin is white, odorless and has a melting point of 62 to 80 ° C.
