Description
Chinese gall, also referred to as Chinese gallnuts (or nutgalls)
are a native product of China.
Now, gallnut extracts are widely used in pharmaceuticals, food and
feed additives, dyes, inks, and metallurgy. Gallotannin is obtained
from natural gallnuts by extraction with hot water; gallic acid is
obtained by the hydrolysis of tannic acid with sulfuric acid. When
heated above **0�C, gallic acid loses carbon dioxide to form
pyrogallol; other chemicals in demand, such as propyl gallate,
octyl gallate, dodecyl gallate, syringic acid, and
trimethoxybenzoic acid, can all be made from gallnuts.
