Abstract: The present invention relates to a method for preferentially breaking cross-links in a vulcanized rubber, thereby de-vulcanizing the rubber, by the use of a supercritical fluid, such as carbon dioxide The supercritical fluid causes swelling of the said vulcanized rubber material, wherein the time of swelling is not more than 50% of the time required for full volume equilibrium swelling of the rubber in said supercritical fluid and the swelling is followed by a rapid reduction of the supercritical fluid pressure The cross links (3) become fully extended and under strain to hold the internal pressures caused by the solvent swelling affect of the supercritical gas When equilibrium swell has been achieved, the pressure within the processing vessel is rapidly dropped to a predetermined level causing a degassing and expansion of the supercritical fluid that has been absorbed within the vulcanized rubber The resulting three dimensional separation of the rubber molecules will put a further rapid strain on the cross l

Abstract: The present invention relates to a method for preferentially breaking cross-links in a vulcanised rubber, thereby de-vulcanising the rubber, by the use of a supercritical fluid, such as carbon dioxide. The supercritical fluid maintained at an appropriate solubility parameter, swells the vulcanised rubber to a state of equilibrium swell. The cross links (3) become fully extended and under strain to hold the internal pressures caused by the solvent swelling affect of the supercritical gas. When equilibrium swell has been achieved, the pressure within the processing vessel is rapidly dropped to a level of not less than 60% of the level at which saturation took place, causing a degassing and expansion of the supercritical fluid that has been absorbed within the vulcanised rubber. The resulting three dimensional separation of the rubber molecules will put a further rapid strain on the cross links, causing them to break (7), thereby giving the affect of de-vulcanisation.

Abstract: According to the invention, a process for the rectification of mixtures of high-boiling air- and/or temperature-sensitive substances which require a high separation efficiency is proposed, in particular a process for the working-up of a VE- or VEA-containing product stream. The process is characterized in particular in that, in a first purification stage, low-boiling products and unspecified isomers of the useful product are separated from the product stream virtually without loss of useful product and that, in a second purification stage, the useful product is removed in a stream having a purity of >97% by weight and a further stream having a purity of >92% by weight. A preferred embodiment of the process serves for working up VEA, in which the loss of useful product in the first purification stage is less than 5%, based on that amount of VEA in the feed which is added to the purification stage per unit time.

The compositions of the invention can be obtained by applying the following method: (a) preparing a mixture comprising at least one reducing carbohydrate and at least one amino acid; (b) keeping the mixture at a temperature sufficient for the reducing carbohydrate and amino acid to react with each other; (c) adding to the mixture a composition comprising arachidonic acid, whereby said arachidonic acid is esterified for at least 50% w/w, preferably at least 65% w/w, more preferably at least 80% w/w, most preferably at least 90% w/w to the glycerol moiety of a triglyceride; and (d) keeping the mixture at a temperature sufficient for the chicken flavor to develop; and possibly: (e) drying the composition under mild conditions. The use of an oil rich in arachidonic acid, whereby said arachidonic acid is esterified to the glycerol moiety of a triglyceride, confers an enhanced stability to the compositions obtained.
