摘要： This invention refers to a process for the synthesis of phenol and acetone starting from cumene hydroperoxide, and to a plant specifically developed for performing this process. More in particular, this invention refers to a process for the synthesis of phenol and acetone starting from cumene hydroperoxide, comprising the following steps: a) Pretreating of the starting cumene hydroperoxide with acidic resins, to obtain cumene hydroperoxide free of inorganic cations; b) Decomposing of the cumene hydroperoxide free of inorganic cations originating from the step (a) in the presence of acidic resins, to yield phenol and acetone.

摘要： A reinforced tubular manufactured article consists of two concentric tubular layers or cylinders (10,12) respectively inner and outer, preferably made of glass fibre reinforced polyester resin, there being housed in the gap between said two cylinders a reinforcing element (14) consisting of a tubular element, preferably a knurled tube, wound in a helical spiral of predetermined pitch about said inner cylinder.
The winding of said knurled tube (14) on the inner cylinder (10) is carried out when the cylinder is only just formed and the polyester resin which constitutes it is still in the paste-like state, so that the resin penetrates into the surface hollows or knurling of said reinforcing tube (14).
