    摘要: A process for the production of carboxyalkyl celluloses having an average degree of substitution of at least 1.0. The process comprises up to 3 stages, but without any intermediate purification. The preferred suspension medium is isopropanol. In each stage of the process, the carboxyalkylating agent is used in quantities of less than 2.5 moles per mole of anhydroglucose unit and the alkylating agent in quantities of less than 5 moles per mole of anhydroglucose unit. The total water content of the system throughout the reaction as a whole must not exceed 450% by weight, based on the quantity by weight of cellulose used. Water contents of from 80 to 250% by weight are preferred.

    摘要: Process and means for purifying cellulose ethers without flocculation points or with relatively high flocculation points (up to 95.degree. C.) and thermoplastic, i.e. highly propoxylated, products made from cellulose in any form, the crude product is first suspended and the suspension liquid subsequently separated in a reverse filter centrifuge a single-stage or multistage wash can be carried out. The filter cake is discharged by reversal of the filter cloth of the centrifuge.

    摘要: The invention relates to a process for the separation of biotechnologically produced valuable materials form a cell suspension by crossflow microfiltration to obtain an high specific permeate flux while retention stays near 0% for long periods. To enable crossflow microfiltration to be carried out on an industrial scale in biotechnology in the separation of biotechnologically produced extracellular valuable materials from a cell suspension, particularly in the separation of alkaline protease for recovering enzyme, under economically acceptacle conditions, alkaline protease of relatively high molecular weight, more especially enzyme >20,000 daltons, is separated from a fermenter solution using polysulfone tubes having micropore diameters of from 0.3 to 0.5 .mu.m at a rate of flow of the fermenter solution of from 3 to 6 m/s parallel to the membrane surface and with a pressure difference between the concentrate side and the permeate side of 2 bar, the ratio of the mean pore diameter of the membrane to the size of the microorganisms remaining in the concentrate being between 0.15 and 0.85

    摘要: A process for making detergent granules having a bulk density of 300 to 700 g/l. A solid carrier containing neutralizing agent is mixed in a rotating mixer with a liquid binding agent containing surfactant acid to forma partially granulated premixture. The premixture is fluidized, sprayed with additional binder, and granulated in a fluidized bed reactor to form the detergent granules.
