Heptanoic acid is made by oxidising heptaldehyde with nitric acid, potassium permanganate in alkaline aqueous solution or acetone solution, potassium dichromate and sulfuric acid, or potassium dichromate and sulfuric acid; and carbonating the sodium and 1-chlorohexane reaction result. Throughout the fourth quarter of 2021, raw material nitric acid prices in Asia reflected a mix of sentiments. After reaching record high estimates in the previous quarter, the price in China fell in the months of October and November. The drop in prices was accompanied by a drop in demand from the agrochemical sector. Many agrochemical and other chemical producers were forced to reduce their production by 50% as a result of the Dual Control strategy, which had a direct impact on the product's demand and pricing dynamics. However, prices of nitric acid rose marginally in December, to roughly 480 USD/MT Ex Work Qingdao, owing to strong demand from the fertiliser sector and rising raw material costs.

About Heptanoic Acid:
Heptanoic Acid, an aliphatic carboxylic acid, is a colourless liquid with a pungent odour. It is poorly miscible in water and is found to float on it as it is less dense than water. The product is a conjugate acid of a heptanoate. It has a flash point of about 200°F. It is a straight-chain saturated fatty acid that contributes to the preparation of esters in the fragrance industry.
Chemical Formula of Heptanoic Acid:
In order to produce Heptanoic Acid from castor oil, the decomposition of esters obtained from castor oil takes place. In this process, the castor oil acid methyl ester decomposition is carried out in the presence of water vapour at 500-600°C to form oenanthal (heptanal) along with undecanoic acid methyl ester. After this, oenanthal is oxidised to produce Heptanoic Acid as the final product.
