Use of a compound of Formula (I) as a metal surface corrosion activator, a formulation containing the same compound and a process by using the same compound for providing a clean metal surface. Said formulation may further comprise water, a solvent such as a dipolar aprotic solvent, a water miscible organic solvent, or an organic base.

Use of phenol compounds as activator for metal surface corrosion

A method for coating a metallic or inorganic substrate is described, such as metal or glass supports, with an organic layer comprising conjugated diene phosphinate or phosphonate compounds.

Method of coating an inorganic substrate with a stable organic layer

A plant for the crystallization of adipic acid is described. A plant for the crystallization of adipic acid, some parts of which are made of a corrosion-resistant material, is also described. The corrosion-resistant material used can be a reference austenitic stainless steel of AISI 310L type, according to the AISI (USA) nomenclature, or X1 CrNi 25-21 (1.4335) type, according to the European nomenclature.

A method for making alkyl hydroperoxide compounds, specifically the preparation of cyclohexyl hydroperoxide is described. The preparation of cyclohexyl hydroperoxide by means of the oxidation of cyclohexane by oxygen in a multi-stage reactor or in reactors connected in series is also described. In these methods, the reactor surfaces in contact with the oxidation medium can be protected by a layer of heat-resistant PFA polymer.
