    摘要： A gel capsule, loaded with at least one organic percarboxylic acid is manufactured by the process comprising the steps of: (a) providing an oil having a melting point below 35° C. at atmospheric pressure and that is inert towards the organic percarboxylic acid; (b) contacting the oil with at least one stabilizer at a temperature of from 25° C. to 50° C. to obtain a liquid matrix medium comprising the oil and the stabilizer, (c) optionally cooling the matrix medium resulting from step (b) to a temperature above the gel-formation temperature of the matrix medium; (d) incorporating at least one organic percarboxylic acid in the form of solid particles into the liquid matrix medium obtained in step (b) to form a dispersion of the solid percarboxylic acid in the liquid matrix medium; (e) contacting the matrix medium obtained in process step (d), with a dispersion agent at a temperature below the gel-formation temperature to form gel capsules, wherein the organic percarboxylic acid is incorporated in an oil/stabilizer-gel matrix.

    摘要： This invention relates to a process for the filtration of liquors containing organic solvents in dry cleaning using natural and/or synthetic layered silicates prepared with one or more ammonium compounds corresponding to the following general formulaR.sup.1 R.sup.2 R.sup.3 R.sup.4 N.sup.+ X.sup.- (I)wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 represent hydrogen, alkyl or alkenyl groups which may optionally be substituted and X.sup.- represents anions of water-soluble, highly dissociated acids, in a quantity of from 2 to 60% by weight.Settling filters or cartridge filters are charged with the layered silicates thus prepared either alone or in combination with kieselguhr and/or active carbon, and solvent mixtures used in dry cleaning are filtered through the prepared filters.The invention also relates to filtration aids for use in the filtration of cleaning liquors from dry cleaning systems which are characterized in that they comprise natural and/or synthetic layered silicates prepared with quaternary ammonium compounds corresponding to general formula (I) above in a quantity of from 2 to 60% by weight, in combination with kieselguhr and/or active carbon.

    摘要： The present invention provides synthetic, finely divided water-insoluble layered silicates having a smectite-like crystal phase, with increased contents of bound alkali and silicate and a distinctly reduced swelling power in aqueous suspension relative to pure layered silicates of this type. The synthetic layered silicate of this invention has the following oxide summation formulaMgO.aM.sub.2 O.bAl.sub.2 O.sub.3.cSiO.sub.2.nH.sub.2 Owherein M is selected from the group consisting of sodium and a mixture of sodium and lithium said mixture having a molar ratio of sodium to lithium of at least about 2,n represents the number of water molecules bound in the crystal phase, anda, b, c and n each represent a number having a value within the following ranges:a is from about 0.05 to about 0.4b is from 0 to about 0.3c is from about 1.2 to about 2.0, andn is from about 0.3 to about 3.0.
