Sorbic Acid powder Usage and Synthesis.

New food preservatives, can effectively inhibit the growth of bacteria, moulds and yeasts, no adverse effects on food, can participate in the role of human metabolism, is internationally recognised as a safe food preservative, can also be used in the pharmaceutical industry, light industry, cosmetic industry, etc., which, as a kind of unsaturated acid, can also be used in the industry of resins, spices and rubber, etc.

Uses of Sorbic Acid powder.

Sorbic acid is currently the most widely used mould inhibitor for food internationally, with the effect of inhibiting the growth and reproduction of microorganisms. Its toxicity is only 1/4 of benzoic acid, and has the tendency to replace benzoic acid. In the food industry is mainly used for cheese, pickled vegetables, dry fruits, fruit juice, fruit syrup, beverages, preserves, bread, candy and other anti-mould, also used for fish and meat products preservation. Sorbic acid as a preservative is also used in the pharmaceutical industry, light industry cosmetics, baked tobacco, and as an insecticide. In addition, it is also used to formulate reagents; as an unsaturated acid used in the resin, spice and rubber industries; there are also applications in feed.

Medicine interactions of Sorbic Acid powder.

Product Method of Bulk Sorbic Acid powder.

Sorbic acid can be obtained by sorbial oxidation, acetone and crotonaldehyde condensation and malonic acid and crotonaldehyde condensation, but at present, both domestic and foreign countries use vinyl ketone method to produce. In addition, butadiene route has a good development prospect because of the low cost of raw materials.

(1) Butadiene route. Butadiene and acetic acid under the catalysis of manganese acetate, 140 ℃ compression synthesis of γ-ethylene-γ-butyrolactone, at 100 ℃, acidic conditions γ-ethylene-γ-butyrolactone hydrolysis can be obtained sorbic acid.

(2) Vinyl ketone method. Containing alkyl phosphate catalyst of acetic acid vapour in 700 ℃ above the cracking tube to stay 0.3 s, the resulting gas mixture with ammonia sauce catalyst transformed into ammonium phosphate and deactivated. Stage-by-stage cooling to -30 - 10 °C was performed to remove water, acetic acid, acetic anhydride, etc.

Vinyl ketone gas is absorbed by crotonaldehyde and catalyzed by boron fluoride (or zinc chloride, cobalt chloride, etc.) to generate polyhexene-4,5-β-lactone (referred to as polyester), polyester hydrolysis under acidic conditions, precipitated after cooling the sorbic acid crude, and then recrystallized with 3-4 times the amount of 60% of the amount of ethanol to get sorbic acid.
