  • Modified process for the direct production of alkyl glycosides
    Patent number: 5559219
    Abstract: Alkyl glycosides are produced by direct synthesis from higher monofunctional alcohols and powder-form glycoses, particularly anhydrous glucose and/or glucose monohydrate, in the presence of acidic catalysts at elevated temperatures, the interior of the reactor being kept under reduced pressure and the glycose being introduced with delay into the alcohol reactants present in excess therein, the alcohol reactants containing the acidic catalyst and being heated to the reaction temperature, while water released in the reaction mixture is removed from the reaction zone via the gas phase. A partial stream is run off from the liquid reaction mixture and delivered to a premixing zone into which the powder-form reactant is simultaneously introduced and is converted with the liquid partial stream into a paste which is delivered to the interior of the reactor via a following intensive mixer.

  • Method of partitioning blood using polyesters
    Patent number: 5556557
    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 due to its lighter and more consistent coloration. The polyester composition can be prepared with relative ease compared to prior art polyesters useful in blood partitioning compositions.

  • Process for the purification of glycerol water
    Patent number: 5527974
    Abstract: The glycerol water (sweet water) accumulating in the high-pressure hydrolysis of natural fats and oils with steam into fatty acid and glycerol is continuously purified. Fats larger than 100 .mu.m in diameter are separated from the aqueous phase in a plate-type phase separator and are returned to the high-pressure hydrolysis process. The aqueous phase thus prepurified is passed through a cross-flow filtration membrane, more particularly a microfiltration membrane, and the concentrate is returned to the entrance of the plate-phase separator. Large product streams of glycerol water can be purified continuously, effectively and particularly economically despite frequent changes of provenance.
