    摘要： Disclosed is a continuous process for the production of bivalent metal peroxides, comprising the steps of introducing into an intensive mixing apparatus a solid, anhydrous or hydrated oxide or hydroxide of a bivalent metal; simultaneously introducing into the intensive mixing apparatus a solution of hydrogen peroxide, whereby the solid bivalent metal compound and the peroxide are intensively mixed and react to produce a reaction mixture containing bivalent metal peroxide; transporting the reaction mixture directly to a rapid dryer; and rapidly drying the reaction mixture to produce the bivalent metal peroxide in solid form.

    摘要： A process for improving the storage behavior of alkali persalts in particularly alkali percarbonates, by preparing a granulate composition therefore is disclosed. The process comprises the steps of:(a) granulating an alkali persalt, wherein the alkali cation is an alkali metal cation or ammonium and which is selected from the group consisting of solid addition-products of an alkali salt with hydrogen peroxide and alkali salts of peroxo-acids in the presence of a sodium phosphate which is selected of sodium polyphosphates and sodium phyrophosphate and of water, and(b) drying the resulting granulate.

    摘要： A process for the preparation of a composition containing diglycerol, in which process at least a stoichiometric amount of isopropylideneglycerol is reacted with .alpha.-monochlorohydrin in the presence of at least one alkaline compound at sufficient temperatures to yield an intermediate product composition containing monoisopropylidenediglycerol and a salt. Most of the salt and water formed is removed from the intermediate product composition, and any unreacted isopropylideneglycerol is removed by distillation. The remaining intermediate product composition containing monoisopropylidenediglycerol is subsequently reacted with water in the presence of at least one acidic catalyst at sufficient temperatures to yield a product composition containing diglycerol and acetone and substantially no cyclic glycerols.

    摘要： The present invention relates to a process for decreasing the content of organic-chemical substances in waste water by chemical oxidation, preferably in the presence of chlorine, and optionally additional alkaline thermal treatment of the waste water, in which the waste water, which has a COD content (chemical oxygen demand) and is alkaline or is rendered alkaline, is introduced into at least one reactor and is treated at a temperature of more than 15.degree. C. with a chlorine-containing and/or chlorine-releasing chemical substance, the introduction of chlorine taking place in a quantity of more than 1 g chlorine/g COD (relative to the chlorine content of the chlorine-containing and/or chlorine-releasing chemical substance), and a molar ratio of OH.sup.- to chlorine of more than 1.5 and a pH value of the waste water of .gtoreq.5 being maintained or set, and the resulting chlorine-treated, hypochlorite-containing waste water is subjected to a reaction time of more than 0.25 hours, with the organic compounds being at least partially oxidized, and subsequently the waste water is treated further and/or is discharged or drained from the reactor.

    摘要： Stabilized crystalline sodium percarbonate is prepared by reacting a soda solution or suspension, which has a pH value of between 10 and 11 and contains an amount of a soluble silicate, e.g., sodium waterglass, which is equivalent to from about 0.2 to about 0.9% of SiO.sub.2 relative to the sodium percarbonate, with a hydrogen peroxide solution which contains a heavy metal complexing agent, allowing to crystallize at least 50% of the sodium percarbonate and then adding to the resulting suspension a second amount of a water soluble silicate which is equivalent to from about 0.2 to about 0.8% of SiO.sub.2 relative to the sodium percarbonate and is sufficient to provide a silicate content in the final product equivalent to 0.5 to 1.5% of SiO.sub.2.

    摘要： Ultra-dry calcium carbonate particles, a method for drying calcium carbonate particles and also the use of the resulting dried calcium carbonate as a flow property regulating agent in sealing compounds or adhesive compositions. The calcium carbonate particles are dried with microwaves. The drying can take place in a continuous belt apparatus, a batch treatment apparatus or a rotary-tube apparatus, and calcium carbonate particles having a degree of dryness of 0 to 0.1% H2O can be obtained.
