Abstract: A polyester is provided which facilitates the separation of blood into light and heavy phases via centrifugation in a blood collection vessel. The polyester is useful as a component of a partitioning composition formulated to have appropriate specific gravity to be positioned intermediate the light and heavy blood phases during centrifugation. A partitioning composition including a polyester of the invention provides a particular advantage in blood collection vessels used in therapeutic drug monitoring, due to the relatively low affinity between the polyester component of the composition and commonly monitored classes of drugs.

Abstract: In the catalytic hydrogenation of fatty acid methyl esters, the fatty acid methyl esters are continuously reacted with hydrogen under pressures of from 20 to 100 bar and at temperatures of from 160.degree. to 270.degree. C. with molar ratios of hydrogen to fatty acid methyl ester substrate of from 10:1 to 500:1. The reaction is carried out over catalysts which contain from 30 to 40% by weight copper, from 23 to 30% by weight chromium, from 1 to 10% by weight manganese, from 1 to 10% by weight silicon and from 1 to 7% by weight barium (% by weight, based in each case on oxidic catalyst mass) and, if desired, other transition metals in the form of their oxides.
