{{Short description|Pure form of carbon produced from sugar}} |

Sugar charcoal is formed by the destructive distillation of [[cane sugar]]. It is also prepared by the dehydration of sugar in the presence of concentrated sulphuric acid (H2So4). Since sulphuric acid is a dehydrating agent, it absorbs water from the sugar and leaves behind black residue of carbon. It is the purest form of [[amorphous carbon]]. |

==Uses of Sugar Charcoal== |

Sugar charcoal is used to prepare artificial diamonds. When heated strongly at high temperature (3000°C-3500°C), it is converted into an artificial diamond. It is used as a [[reducing agent]] in the process of extraction of metals. It can also be used as a decolourising agent. |

Sugar charcoal is formed by the charring of cane sugar, which was repeatedly recrystallized to remove any organic impurities.[1] It is also prepared by the dehydration of sugar in the presence of concentrated sulfuric acid. Since sulfuric acid is a dehydrating agent, it absorbs water from the sugar and leaves behind black residue of carbon. It is the purest form of amorphous carbon.[citation needed]
Use
[edit]Since sugar charcoal is a method of producing very pure carbon it is used to prepare artificial diamonds. When heated strongly at high temperature (3000-3500 °C) and high pressure, it is converted into an artificial diamond.
It is used as a reducing agent in the process of extraction of metals.
Sugar charcoal has decolourizing properties, which means it removes some dyes, such as methylene blue,[1] from water.
