What is the Difference Between N-Valeric Acid and Isovaleric Acid? Where is the difference?

Performance and application of n-valeric acid

[alias]valeric acid,valerianOxalic acid, Chuanxinpai oxalic acid.

[Molecular formula]C5H10O2

[Structural formula]CH3(CH2)3COOH

[Properties]N-valeric acid is a colorless and transparent liquid with a putrid smell. The relative density is 0.9391 (20°C), the boiling point is 186.05°C (101kPa), and the melting point is -34°C. The flash point (open cup) is 51°C, and the refractive index is 1.4086 (20°C). Slightly soluble in water, the solubility in water is about 3% (weight) (20°C), soluble in ethanol and ether.

[Use] Used in organic synthesis to prepare valeric acid esters. It is also used in the manufacture of spices, plasticizers, drugs, disinfectants, etc.

[Brief recipe]

①N-amyl alcohol is produced by electrolytic oxidation.

② Obtained from distilling valerian.

[Safety and Protection]Packed in plastic drums or stainless steel drums, each drum has a net weight of 100kg or 200kg. Store and transport according to general chemical regulations.

This product is low in toxicity and has an irritating effect on the skin and mucous membranes. When the skin touches it, it should be washed with water immediately.

Properties and uses of isovaleric acid

［alias］3-Methylbutyric acid, isopropylacetic acid, isovalerenic acid, and isotracentate oxalic acid.

[Molecular formula]C3H10O2

[Structural formula](CH4)2CHCH2COOH

［Property］ Isovaleric acid is a colorless and transparent liquid with a strong unpleasant smell and sour taste. Fragrant, and lingonberry-like. The relative density is 0.9286 (20°C), the boiling point is 176.7°C, the melting point is -29.3°C, and the refractive index is 1,4043 (20°C). Exist in valerian, hop oil, tobacco. Soluble in 24 parts of water, miscible with ethanol, ether, chloroform, etc.

[Use] Used in organic synthesis. Preparation of ethyl isovalerate, benzyl isovalerate, isopentyl isovalerate, phenylethyl isovalerate, etc. It is also used in the manufacture of medicines, synthetic spices, and the preparation of flavors and food flavors.

[Brief recipe]

① Isovaleraldehyde is produced by catalytic oxidation.

② Obtained from distilling valerian.

[Safety and Protection]Packed in plastic barrels or stainless steel barrels, with a net weight of 100kg or 200kg, and stored and transported according to the regulations for general chemicals. Isovaleric acid is generally considered safe for use. It is one of the artificial food flavors that can be added to food without harming human health.
