Abstract
Use of a composition comprising silicon, oxygen and at least one of calcium, potassium, or titanium, as a material for coating an equipment or as a constituent material of equipment, intended to be in contact with a mixture containing a chlorohydrin, hydrogen chloride and water. The use of the composition may provide a method for reducing corrosion of the equipment, for decreasing the frequency of replacement of the equipment and/or for lowering the risks linked to equipment breakage and leak. The equipment which is intended to be in contact with the mixture may be used in a process for manufacturing a chlorohydrin, in which a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture of the two, is reacted with a chlorinating agent that contains hydrogen chloride.
