The characterisation of acetic acid "wood vinegar"

The acetic acid is formed, just as the methanol, from the methoxy groups of the Iignins. The acetic acid content of the distillate is approx. 6%, which is about three times higher than that of methanol.

An indication that further decomposition products are formed should be given.

Learning objectives

• Acetic acid is, among other substances, produced by the dry distillation of wood.
• This so-called wood vinegar is an acid and can be distinguished from other distillation products (e.g. methanol) with indicators.

Benefits

• Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
• Experiment is part of a complete solution set with experiments for the topic Organic Chemistry matched with international curriculum: all topics are covered
