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.

Use of compositions containing silicon for improving the corrosion resistance of vessels

Process for the manufacture of dichloropropanol in which glycerol is reacted with a chlorinating agent comprising hydrochloric acid in a liquid medium in equilibrium with a vapor phase and in which the condensation of a fraction exhibiting the composition of the vapor phase is prevented.

Process for the manufacture of dichloropropanol by chlorination of glycerol

Process for preparing a chlorohydrin, comprising a step in which a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture thereof is subjected to reaction with a chlorinating agent containing hydrogen chloride and at least one other step, carried out in apparatus made from or covered with materials which are resistant to the chlorinating agent under the conditions in which this step is realized.
