摘要： Cogranulates of high bulk density which easily disintegrate in water and comprise aluminosilicates and crystalline sodium silicates having a layered structure. The aluminosilicates contained therein are those of the formula M.sub.2/n O.Al.sub.2 O.sub.3. XSiO.sub.2. yH.sub.2 O in which M is an alkali metal or alkaline earth metal, n indicates the valency of the cation, x is.gtoreq.2 and y has a value of between 0 and 8. The sodium silicates have an SiO.sub.2 /Na.sub.2 O ratio of (1.8 to 4.2):1. These cogranulates are prepared by mixing the pulverulent aluminosilicates and sodium silicates with one another and introducing the mixture into a zone in which it is compacted between two rolls rotating in opposite directions to form a compact. After comminution of the compact, the desired particle sizes are finally separated off from the oversize and undersize material. The cogranulates can be used in detergents and cleaning agents.

摘要： Hexagonal phosphorus pentoxide of diminished reactivity is made by burning liquid yellow phosphorus with a mixture of dry air and pure oxygen inside a combustion zone with the resulting formation of a gas stream containing phosphorus pentoxide; next, the gas stream coming from the combustion zone is passed initially through an intermediary zone indirectly cooled by means of fluidized matter and then through a condensing zone fitted with an immersion tube indirectly cooled by means of fluidized matter; the gas stream is passed through the immersion tube at a mean temperature of 450.degree. to 600.degree. C. and allowed to remain in the immersion tube over a period of 2 to 5 seconds.

摘要： Residue obtained upon the removal of heavy metal contaminants from crude phosphoric acid by means of a dialkyldithiophosphoric acid ester and adsorbent is worked up into ecologically reliable solid matter and into a heavy metal concentrate. The solid matter and heavy metal concentrate are separated from one another by successive mechanical and chemical treatment. The sequential order of these two operational steps can be inversed.

摘要： For working up concentrated, preferably partially condensed phosphoric acid which is contaminated with organic components, the phosphoric acid is first thoroughly mixed with fine-grained sand in a weight ratio of (0.5 to 1.5):1. Then, to neutralize the mixture, a basic, oxygen-containing calcium compound is added, while the thorough mixing is continued, until a 10% aqueous suspension of the mixture to which the calcium compound has been added has a pH between 5 and 11. Finally, the mixture which contains the calcium compound is commminuted after cooling.
