METHOD FOR ACYLATING A HYDROXYLATED SOLID MATERIAL

The invention relates to a method for chromatogenic acylation of a solid material (1, 2) carrying hydroxyl groups capable of reacting with fatty acid chlorides in the gaseous state, wherein: a reactive fatty acid chloride composition (20, 21, 22) is applied to the surface of the solid hydroxyl mater...

Beschreibung
Zusammenfassung:	The invention relates to a method for chromatogenic acylation of a solid material (1, 2) carrying hydroxyl groups capable of reacting with fatty acid chlorides in the gaseous state, wherein: a reactive fatty acid chloride composition (20, 21, 22) is applied to the surface of the solid hydroxyl material (1, 2) by means of an applicator capable of releasing the composition (20, 21, 22) on the surface of the material (1, 2). According to the invention, the composition (20, 21, 22) is applied to the surface of the solid hydroxyl material (1, 2) at an acylation temperature lower than the vaporisation temperature of at least one fatty acid chloride of the composition (20, 21, 22) to allow acylation of the material (1, 2) by reaction of at least one fatty acid chloride in the gaseous state of the composition (20, 21, 22) with at least one of the hydroxyl groups of the material (1, 2), the acylation temperature being between 160°C and 250°C.
