  • Patent number: 11236282
    Abstract: Copolymers comprising C14 to C50 olefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C18- to C50-alkyl groups and secondly esters with short-chain linear, branched or cyclic alkyl groups, or esters with aromatic groups. The invention further relates to a process for preparing copolymers of this kind and to the use thereof as pour point depressant for crude oil, mineral oil and/or mineral oil products, preferably as pour point depressant for crude oil.

  • Publication number: 20100130385
    Abstract: A process for preparing a paraffin inhibitor formulation comprising (a) preparing a mixture comprising a waxy paraffin inhibitor component having a melting point of >0° C. and an emulsifier component, wherein the mixture is prepared at a first temperature range above the melting point of the waxy paraffin inhibitor; (b) adding water to the mixture to produce an o/w emulsion; and (c) cooling the o/w emulsion to a temperature in a second temperature range which is below the melting point of the waxy paraffin inhibitor. The mixture prepared in step (a) may further comprise water to produce a w/o emulsion, the water being present in a proportion by weight that is lower than the sum of the proportions by weight of the paraffin inhibitor and the emulsifier component. The process may further comprise (d) adding an at least partially water-miscible organic solvent in which the paraffin inhibitor is insoluble.
