    摘要: The invention relates to a method for the manufacture of an electrolyte and acetic acid granulate for making a hemodialysis solution, the granulate comprising the electrolytes potassium chloride, calcium chloride and magnesium chloride, and the method comprising preparing the granulate and adding a desired quantity of acetic acid. The granulate, which is easy to process and has free flow capability, is made by crushing the electrolyte salts to a grain size of less than 0.5 mm and subsequently granulating the electrolyte salts in a dry gas atmosphere to a granulate having a grain size of 1 to 10 mm and a pore volume of more than 25 percent by volume. Subsequently, the acetic acid is added to the granulate, preferably by spraying.

    摘要: Oxidized polyethylenes useful as water-emulsifiable waxes and as lubricants in the extrusion of polyvinyl chloride are prepared by oxidizing finely divided polyethylene of high density at elevated temperatures with an oxidation gas of air and/or oxygen, the oxidation gas supplied per hour containing not less the 100 mg of ozone per kilogram of polyethylene, by performing the oxidiation in a paddle dryer and passing the oxidation gas into the free gas space above the polyethylene, the temperature in the paddly dryer preferably being continuously adjusted to from 1.degree. to 2.degree. C. below the softening point of the polyethylene.
