摘要： A process for reducing the salt content of fractions comprising high boilers obtained in the preparation of phenol from cumene, by extraction, is claimed. In the preparation of phenol from cumene, not only phenol and acetone but also by-products such as dimethyl phenyl carbinol or acetophenone are formed in the cleavage of cumene hydroperoxide. In the work-up of the cleavage product phase by distillation, these by-products are obtained as a fraction which boils only at high temperatures. These fractions further comprise alkali metal in the form of salts as a result of the neutralization by means of aqueous sodium hydroxide after the acid catalyzed cleavage. The presence of salt in this phase makes the work-up of this phase considerably more difficult. The salt is usually removed from the fraction by extraction of the fraction with water. However, considerable problems can occur if the aqueous phase cannot be cleanly separated from the organic phase. According to the invention, not only water but also an organic liquid is added to the fractions comprising high boilers for the purposes of extraction. This aids and accelerates the subsequent phase separation. The organic liquid to be added to the fractions comprising high boilers can be removed again from the treated fractions by simple distillation. Furthermore, the process of the invention lowers the phenol content of the fractions comprising high boilers and phenol is recovered. Fractions comprising high boilers which have been treated according to the invention can be used as starting material for the production of carbon black.

摘要翻译： 要求保护包含从异丙苯制备苯酚得到的高沸点馏分的馏分的盐含量的方法。 在从异丙基苯制备苯酚时，在氢过氧化枯烯的裂解中不仅形成苯酚和丙酮，而且还产生二甲基苯基甲醇或苯乙酮等副产物。 在通过蒸馏处理裂解产物相时，这些副产物作为仅在高温下沸腾的馏分获得。 由于在酸催化裂解后通过氢氧化钠水溶液中和，这些级分还包含盐形式的碱金属。 在这一阶段盐的存在使得这一阶段的后处理更加困难。 盐通常通过用水萃取级分从馏分中除去。 然而，如果水相不能与有机相清洁分离，则可能会发生相当大的问题。 根据本发明，为了提取的目的，不仅将水，而且有机液体加入到包含高锅炉的馏分中。 这有助于并加速随后的相分离。 通过简单蒸馏，可以从经处理的馏分再次除去加入到包含高锅炉的馏分中的有机液体。 此外，本发明的方法降低了包含高锅炉和苯酚的馏分的苯酚含量。根据本发明已经处理的包含高锅炉的馏分可以用作生产炭黑的起始原料。

摘要： An interspinous process spacer for implantation in an interspinous space between a superior spinous process and an inferior spinous process includes a balloon-like body, a first deployable protrusion and a second deployable protrusion. The body has a distal end, a proximal end and a longitudinal axis extending between the proximal and distal ends. The spacer is arrangeable in an unexpanded configuration and an expanded configuration. The first deployable protrusion is mounted proximate the proximal end and the second deployable protrusion is mounted proximate the distal end. The first and second deployable protrusions are oriented generally parallel to the longitudinal axis in the unexpanded configuration and generally perpendicular to the longitudinal axis in the expanded configuration.

摘要： The present invention deals with the proteolytic enzyme thermolysin which tends to be unstable in aqueous solution. The invention provides methods and compositions to enhance the stability of dissolved thermolysin in aqueous solution. Thermolysin, crude thermolysin or a lyophilizate containing thermolysin and one or more salts, is contacted with an aqueous buffer with a low salt concentration and a first solution is formed. Subsequently, a further salt in solid form is added and dissociated, thereby forming a second solution comprising thermolysin in a stabilized form.
