Uses and synthesis of Dehydroacetic acid powder

Dehydroacetic acid powder, also known as dehydroacetic acid, abbreviated as DHA, molecular formula C8H8O4, molecular weight 168.15, Dehydroacetic acid CAS 520-45-6 is a colourless crystal or light yellow powder, insoluble in water, soluble in benzene, ethyl ether, acetone and hot ethanol.

Dehydroacetic acid Raw Materials is a low-toxicity, highly efficient, broad-spectrum antimicrobial agent, widely used in coatings, oils, leather products, food, feed, packaging materials and cosmetics, mould preservation.

Applications / Functions of Dehydroacetic acid powder

• Dehydroacetic acid CAS 520-45-6 is a broad-spectrum antiseptic for feedstuffs, which can inhibit the growth of moulds, yeasts and bacteria. Anti-bacterial effect is basically independent of PH, but the best antiseptic effect under neutral conditions.
• Dehydroacetic acid powder Used as preservative, synthesis intermediate of chloropicrin
• Dehydroacetic acid Raw Materials is a broad-spectrum food preservative that inhibits the growth of moulds, yeasts and bacteria. The inhibitory effect is largely independent of the Ph value, but the best preservative effect is achieved under neutral conditions.
• Preservative; mould inhibitor.

Dehydroacetic acid powder is an organic synthesis intermediate, toughening agent, and broad-spectrum food preservative.

Physicochemical Property of Dehydroacetic acid powder

DHA is widely found in many deep-sea fish oils, as well as in marine algae and some land plants.DHA is an omega-3 unsaturated fatty acid, which is an essential fatty acid for the body's nutrition. mp44℃.

Dehydroacetic acid CAS 520-45-6 is very unstable to light, oxygen and heat, easy to oxidise and crack, usually should add antioxidant. Can also add lecithin, dextrose, cyclodextrin or inert gas, etc., to improve the stability of the preparation.

Production methodprocess of Dehydroacetic acid powder

1. The commonly used methods are ethyl acetoacetate dehydrocondensation and bis-vinyl condensation. The synthetic process of bis-vinyl ketone method has the advantages of low cost and high yield.
2. Dehydroacetic acid CAS 520-45-6 is formed by the condensation of bis(vinylidene)ketone under alkaline conditions (e.g., in the presence of sodium ethanol, sodium phenol, sodium hydroxide, sodium acetate, pyridine, triethylamine) or catalyzed by aluminium bromide.
