摘要： Carbonyl compounds (e.g. acetone and acetaldehyde) are often present as impurities in oxygenated organic liquids such as acetic acid made by the carbonylation of methanol or in phenol produced by the oxidation of cumene. These impurities can render petrochemical products unsuitable for long-term storage or otherwise adversely affect downstream processing operations. It has now been found that detrimental carbonyl impurities can be easily removed from oxygenated organic liquids by contact with resins having amine functional groups.
摘要翻译： 羰基化合物（例如丙酮和乙醛）通常作为杂质存在于氧化的有机液体中，例如通过羰基化甲醇或通过异丙苯的氧化产生的苯酚制得的乙酸。 这些杂质可能导致石化产品不适合长期储存或以其他方式不利地影响下游加工操作。 现在已经发现，通过与具有胺官能团的树脂接触，可以容易地从有氧氧化有机液体中除去有害的羰基杂质。

摘要： A novel process for the regeneration of a solid adsorbent which is at least partially spent and has a reactive metal (e.g. silver) dispersed thereon is disclosed. The regeneration consists of a step whereby accumulated metal-containing reaction products formed during adsorptive service are removed by stripping the spent or partially spent adsorbent with a suitable stripping solution such as sodium thiosulfate. After detrimental metal-containing deposits are stripped, the adsorbent is then subjected to a reactivation step in which the regenerated adsorbent is contacted with a solution containing a reactive metal compound (e.g. silver nitrate). Reactivating the adsorbent therefore adds an incremental amount of the reactive metal onto the adsorbent. Regeneration of the adsorbent according to the two-step method of the present invention thus effectively prolongs its useful life. The present invention is particularly applicable to adsorbents used in processes involving the adsorption of iodine-containing compounds from contaminated feed streams.

摘要： The present invention is a single vessel apparatus for separating at least a first component from a second component of a process stream. The apparatus has a vertically-elongated vessel which contains a plurality of vertically spaced apart distillation contactors for vapor and liquid distillation and an adsorbent-retaining volume defined at least in part by a solids-impermeable member located above the contactors for passing a fluid into the retaining volume. The apparatus also contains a mechanism for adding adsorbent above the solids-impermeable member and a mechanism for withdrawing adsorbent particles from the retaining volume to contact the fluid with adsorbent particles and to provide at least intermittent downward gravity flow of adsorbent particles through the retaining volume and to selectively adsorb a portion of the fluid. The apparatus further contains a regenerator for desorbing fluids from adsorbent particles which is in communication with the mechanism for adding adsorbent above the solids-impermeable member and the means for withdrawing adsorbent particles from the adsorbent-retaining volume. The fluids are desorbed in the regenerator by passing a regenerant into and collecting the regenerant from the regenerator. Finally, the apparatus also contains a mechanism for adding fluid to and withdrawing fluid from the vessel. The benefit of the invention is a high purity single vessel separation unit at reduced capital equipment costs.

摘要： Lactic acid formed via fermentation generally is susceptible to the development of color bodies when heated to temperatures of approximately 180.degree. C. and above. Color development appears to result from carbonization of small amounts of carbohydrates. Consequently a heat-stable lactic acid may be produced by subjecting an aqueous solution of lactic acid to temperatures between about 180 and 230.degree. C. for a time sufficient to carbonize the carbohydrates, with subsequent removal of the color bodies using standard decolorants such as activated charcoal. Heat treatment may be applied either directly to the broth or to an aqueous solution resulting from one or more processing steps applied to the fermentation broth.
