(a) treatment of the contaminated water with an inorganic acid up to a pH ranging from 4.0 to 4.5 with the elimination of the carbon dioxide thus formed;
(b) dispersion in the water of solid particles of a metal oxide of the semiconductor type or dissolution of a stream consisting of ozone in pure oxygen or air;
(c) irradiation of the dispersion or solution obtained in step (b) with ultraviolet light to degrade the ether-based contaminants.摘要翻译： 描述了由醚类化合物，特别是甲基叔丁基醚（MTBE）或其类似产物污染的水的净化过程的光降解方法，其包括以下步骤：（a）用无机酸处理受污染的水直至pH 范围为4.0至4.5，消除由此形成的二氧化碳; （b）在半导体类型的金属氧化物的固体颗粒的水中分散或在纯氧或空气中溶解由臭氧组成的物流; （c）用紫外线照射步骤（b）中得到的分散体或溶液以降解醚类污染物。

摘要： A process is described for the contemporaneous preparation of mesitylene and durene, characterized in that mesitylene and durene are obtained exclusively starting from pseudo-cumene without the use of any further chemical compound, operating in continuous, at a temperature ranging from 210 to 400°C, at a pressure ranging from 1 to 50 bar, with a weight space velocity ranging from 0.1 to 20 hours -1 and in the presence of a catalyst based on crystalline metal-silicates in acid form. After the recovery of mesitylene and durene from the reaction raw product, some of the remaining components of the raw product itself are recycled and fed to the reactor together with the pseudo-cumene.

摘要： The present invention relates to a process for the preparation of zeolitic catalysts comprising zeolite and oligomeric silica, which can be used in industrial reactors. The process consists in directly mixing the suspension, resulting from the synthesis of the zeolite, with an oligomeric silica sol, obtained from the hydrolysis of a tetra-alkyl ortho silicate in the presence of tetraalkylammonium hydroxide, and in subjecting the mixture to rapid drying, by feeding to a spray-dry.
