摘要： The invented process for producing sorbic acid includes the step of decomposing a polyester at temperatures of 100° C. or less with hydrochloric acid, which polyester is obtained from ketene and crotonaldehyde. In the process, the reaction temperature after the initiation of a polyester decomposition reaction is controlled by adding a hydrochloric acid to a reaction mixture, which hydrochloric acid has a temperature lower than that of the reaction mixture, for example, a temperature of 50° C. or less. Such hydrochloric acid for reaction control may have a concentration of, for example, 23% by weight or more. This process can yield sorbic acid in a short time in a high yield and can highly efficiently produce sorbic acid.

摘要： Crude sorbic acid produced in a decomposition step 1 is subjected to a crystallization step 2 to precipitate crystalline sorbic acid, and the crystalline sorbic acid is separated from a mother liquor (filtrate). The mother liquor was subjected to an extraction step 3 in which a specific extractant is employed, and an extract (organic phase) is subjected to a back extraction step 4 and treated with an alkaline solution to extract the sorbic acid into an aqueous phase in the form of a salt. The aqueous phase is neutralized in a neutralization step 6 and the produced sorbic acid is recovered in a separation step 7. As the extractant, use can be made of an organic solvent which is separable from water and has a solubility in water of not more than 1% by weight and in which not less than 0.5% by weight of sorbic acid is dissolvable (e.g., aliphatic C6-20 alcohols, ketones, esters, aromatic ethers). According to the above process, sorbic acid can be recovered from a filtrate (mother liquor) produced in a sorbic acid production process with high recovering efficiency and therefore results in a consequent and effective reduction in the BOD of the waste liquid.

摘要： The invented process for producing a polyester supplies a crotonaldehyde with a purity of 95% by weight or more to a reaction system in the reaction of ketene with crotonaldehyde. In this process, unreacted crotonaldehyde may be recovered from a reaction mixture obtained by the reaction of ketene with crotonaldehyde and may be recycled to the reaction system. The &agr;vinylcrotonaldehyde content of the crotonaldehyde to be supplied to the reaction system is, for example, less than 0.5% by weight, and the paraldehyde content of the crotonaldehyde to be supplied to the reaction system is, for example, less than 5% by weight. By decomposing the above-prepared polyester with, for example, hydrochloric acid, a sorbic acid having a satisfactory hue can be efficiently obtained.

摘要： A process produces sorbic acid by hydrolyzing a polyester with an aqueous hydrochloric acid solution having a concentration of 15% by weight or less under the application of pressure or at a temperature of 100° C. or higher, which polyester is obtained by reaction between crotonaldehyde and ketene. In this process, the polyester may be hydrolyzed with a 3 to 10% by weight aqueous hydrochloric acid solution at a temperature of from 115° C. to 140° C. A reaction mixture after hydrolysis of the polyester may be subjected to solid-liquid separation and the resulting filtrate may be recycled and reused in the hydrolysis reaction of the polyester. This process can significantly reduce the amount of tar formed during decomposition of the polyester, can produce sorbic acid in a high yield, and can reduce the load on the treatment of waste filtrates formed during purification operation.

摘要： A process produces sorbic acid or its salt and includes the step of retaining a slurry or solution containing sorbic acid or its salt while holding an oxygen concentration of a gaseous phase at 4% by volume or less, the gaseous phase being in contact with the slurry or solution containing sorbic acid or its salt. In the process, the oxygen concentration of the gaseous phase may be held at 4% by volume or less while introducing an inert gas into a gaseous phase of a reservoir holding the slurry or solution and/or of a conduit adjacent to the reservoir. Such an inert gases includes, for example, nitrogen gas. The oxygen concentration of the gaseous phase is preferably held at 1% by volume or less. The process can prevent the formation of new color-inducing substances in a purification operation of sorbic acid or its salt, and the obtained sorbic acid or its salt has a minimized degree of coloring and a minimized deterioration of hue over time.
