Abstract (en)
[origin: WO2011003899A1] The present invention relates to a method for continuously delivering a fluid used as a feedstock in a chemical reaction by means of a positive displacement pump comprising spatially separated delivery valves and a fluid-filled transfer line between the positive displacement pump and delivery valves, characterized in that an auxiliary fluid, which is a product or a reactant of the chemical reaction and has a melting point that is below the melting point or below the saturation temperature of the fluid to be delivered, is present in the transfer line. The present invention further relates to the use of a product of an aromatic compound resulting from hydrogenation as an auxiliary fluid for delivering an aromatic compound, and to the use of an alcohol or an ester of alcohol and carboxylic acid as an auxiliary fluid for delivering carboxylic acids or carboxylic acid derivatives.
