摘要： The invention relates to a method for preparing polyglycerol, comprising —providing a catalyst salt on a support, the catalyst salt having catalytic activity with respect to an etherification reaction of a polyol selected from the group of glycerol and oligoglycerols, —contacting the catalyst salt on the support with a fluid phase comprising a polyol selected from the group of glycerol and oligoglycerols, —and subjecting the polyol in the fluid phase to an etherification reaction in the presence of the catalyst salt, thereby forming the polyglycerol.

摘要： This invention relates a wax inhibitor for hydrocarbon oils comprising an esterified copolymer having repeating structural units derived from an esterified ethylenically unsaturated dicarboxylic acid and α-olefins having at least 18 carbon atoms, whereof at least 3 mol-% of the α-olefins have 30 or more carbon atoms, and wherein the ethylenically unsaturated dicarboxylic acid has been esterified with a mixture of alcohols comprising
i) 70 to 97 mol-% of a saturated fatty alcohol having 18 to 24 carbon atoms and
ii) 3 to 30 mol-% of an unsaturated alcohol having 16 to 24 carbon atoms.
