Psyllic acid is a saturated fatty acid

Saturated fat

Saturated fat is fat that consists of triglycerides containing only saturated fatty acids. Saturated fatty acids have no double bonds between the individual carbon atoms of the fatty acid chain. That is, the chain of carbon atoms is fully "saturated" with hydrogen atoms...

Alkali salts

The alkali salts of psyllic acid are precipitated when alcoholic solutions of the acid and an alkali hydroxide

Alkali hydroxide

The alkali hydroxides are a class of chemical compounds which are composed of an alkali metal cation and the hydroxide anion . The alkali hydroxides are:*Lithium hydroxide *Sodium hydroxide *Potassium hydroxide...

 are mixed. The silver and barium salts can be obtained by adding aqueous alcoholic solutions of silver nitrate

Silver nitrate

Silver nitrate is an inorganic compound with chemical formula . This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides...

 and barium chloride

Barium chloride

Barium chloride is the inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. It is also hygroscopic....

 to alcoholic solutions of the acid. The following salts have been analyzed: C38-H65-O2-Na, C-66-H130-O4Ba, and C33-H65-O2Ag. Psylla wax is hydrolysed by alcoholic potassium hydroxide

Potassium hydroxide

Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash.Along with sodium hydroxide , this colorless solid is a prototypical strong base. It has many industrial and niche applications. Most applications exploit its reactivity toward acids and its corrosive...

 as well as by hydrobromic acid

Hydrobromic acid

Hydrobromic acid is a strong acid formed by dissolving the diatomic molecule hydrogen bromide in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at 124.3 °C and contains 47.6% HBr by weight, which is 8.89 mol/L. Hydrobromic acid has a pKa of −9, making it a...
