Natural Isovaleric Acid CAS 503-74

Odowell is a professional China Natural Isovaleric Acid CAS 503-74 manufacturers and China Natural Isovaleric Acid suppliers. Natural Isovaleric Acid is obtained by oxidation of isoamyl alcohol or isovaleraldehyde. Add potassium permanganate, sodium carbonate and isoamyl alcohol into water, stir and heat up to 50-70 ℃, react for 3h, filter, and wash manganese mud with hot water. Combine the filtrate, wash and concentrate. Cool to 40 ℃, slowly add sulfuric acid to pH=2-3, leave the Chemicalbook still, separate the oil layer, fractionate, and collect the 173-176 ℃ fraction to obtain isovaleric acid with a yield of 48%. Isovaleraldehyde is oxidized by air at 30-40 ℃ with manganese acetate as catalyst. The product is distilled and the distillate at 173-178 ℃ is collected to obtain a finished product with a purity of more than 95%..Odowell is ploughing in Flavors & Fragrances industry since 2012, constantly looking for new raw materials and new technology to fulfill perfumers and flavorists’ growing pursuit of product variety and quality.
