Crosslinked glycerol or oligoglycerol esters, and use thereof as an additive in drilling fluids
Abstract:
The present invention relates to a crosslinked glycerol or oligoglycerol ester which can be obtained by crosslinking a non-crosslinked glycerol or oligoglycerol ester which can be obtained by reacting an (A) acid phase comprising (a1) a fatty acid, (a2) a dicarboxylic acid, (a3) a dimeric fatty acid, (a4) an oligomeric fatty acid, (a5) a hydroxy fatty acid or (a6) a mixture of at least two thereof, with a (B) alcohol phase comprising (b1) monoglycerol, (b2) diglycerol, (b3) triglycerol, (b4) oligoglycerol made up of more than three glycerol units, (b5) an alkoxylate of glycerols (b1), (b2), (b3) or (b4), or (b6) a mixture of at least two thereof, forming a full or partial ester and crosslinking the full or partial ester by means of a crosslinking agent, wherein the crosslinking can take place during or after the formation of the full or partial ester.
