    摘要： There is provided a process for the separation of aromatic hydrocarbons mixtures into single components, in which the mixtures in vapor phase pass onto an adsorption bed formed by a potassium-exchanged Y zeolite, which is preventively saturated with desorbent vapors. According to the invention the desorbent used is isopropylbenzene in vapor phase. This facilitates the quick separation of the pure components, with the exception of the presence of desorbent. The process according to this invention is quicker in comparison to traditional ones. It requires the use of lower charges of desorbent and allows the separation of single pure components of the mixtures. It especially improves the paraxylene separation in higher concentrations with respect to the desorbent.

    摘要： This invention refers to a process for the synthesis of cumene hydroperoxide and to the product thus obtained.More in particular, this invention refers to a process for the production of cumene hydroperoxide by oxidating cumene with oxygen, where this process is run in the presence of a basic medium insoluble in the reaction environment, and such as not to release inorganic cations to the reaction environment. Such a basic medium is preferably a pyridinic resin.The cumene hydroperoxide thus obtained, characterized by the fact of being free of inorganic cations, is a further object of the invention.

    摘要： A description is given here of a novel process for the production of monocarboxylic and polycarboxylic aromatic acids by the catalytic oxidation in homogeneous phase of aromatic compounds carrying at least one oxidizable substituent group attached directly to the carbon atom of the corresponding aromatic nucleus. The novel process according to the present invention comprises the steps of: a) catalytically oxidizing the corresponding aromatic precursors in liquid phase in the presence of gaseous oxygen; b) filtering the end product; c) recycling into the oxidation reactor at least part of the mother liquors resulting from the filtration stage, and is characterized by the fact that said steps from (a) to (c) are carried out in a closed and continuous cycle operating substantially under the same pressure and temperature conditions, preferably at 2-10 barg and 100-140° C.
