Abstract: This invention relates to homogeneous, anhydrous formulations which contain glycerophospholipids and polar or lipophilic substances (eg, physiologically active ingredients) in a molar ratio of 1:0.001 to 1:2, and maybe anhydrous formulation aids, eg, in the form of glycerol, in a molar ratio of 1:0.001 to 1:1, expressed in terms of the glycerophospholipids, the components forming such stable aggregates with one another as to render the formulations ideal for the preparation of dispersions, emulsions and/or suspensions in many fields of application, these including the food-processing sector, biotechnology, and the pharmaceuticals industry. The formulations are produced in an extraction column using compressed hydrocarbons, and are obtained from the column as a melt.

Abstract: The invention relates to oil-free glycerophospholipid formulations which contain a homogeneous mixture of glycerophospholipids and an anhydrous, liquid polyol compound such as glycerol in a molar ratio of 1:0.1 to 1. These formulations are produced, eg, by extracting a starting material consisting of an oil-containing glycerophospholipid (mixture) and the polyol component with a compressed hydrocarbon (mixture) in a rectifying column. The oil-free formulation can be obtained from the melt at the bottom of the column in the form of free-flowing powder, which is ideally suited for stabilising oil-in-water emulsions.

Abstract: To prepare N-phosphonomethyl glycine,a) aminomethylphosphonic acid or one of its salts in water, if necessary or desirable with the addition of lyes, is reacted with an alkali carbonate and/or alkali hydrogencarbonate or with carbon dioxide and a lye,b) the resulting alkali salt of N-phosphonomethylcarbamic acid is subsequently hydroxymethylated with formaldehyde,c) the salts, resulting from b), of N-hydroxymethyl-N-phosphonomethyl-carbamic acid, if necessary or desirable with addition of a lye, are reacted with hydrocyanic acid and/or a cyanide andd) the N-carboxy-N-phosphonomethylglyconitrile salts thus obtained are treated with acids and converted by means of hydrolysis and decarboxylation into N-phosphonomethyl glycine.In this way, it is possible to obtain excellent yields of high-purity N-phosphonomethyl glycine.

Abstract: Disclosed is a process for producing calcium cyanamide by reacting urea with an oxygen-containing calcium compound in at least two stepsa) in a first step the reaction components are allowed to react under compression and/or while being revolved or by applying them to a hot surface at temperatures of 120.degree. to 500.degree. C. until a solid is formed andb) the solid reaction mixture that is formed is subsequently calcined at temperatures of 600.degree. to 900.degree. C.In this process it is possible to obtain high yields and throughputs of calcium cyanamide without requiring a time-consuming processing of the reaction product after the first or second step.
