    摘要： In a continuous process for the preparation of phosphorous acid with simultaneous production of hydrochloric acid, a reaction zone is provided which is in open communication with a first scrubbing zone. A portion of the reaction product is recycled from the bottom of the reaction zone into the top of the scrubbing zone and phosphorous acid is removed from the circulation. Hydrogen chloride gas escaping from the top of the first scrubbing zone is brought into contact, in a cooled, second scrubbing zone, with an overstoichiometric amount of water. Hydrochloric acid is obtained which is passed as starting material into the reaction zone or into the top of the first scrubbing zone. The external cooling of the second scrubbing zone is controlled such that the temperature in the reaction zone is kept constant at a desired value between 90.degree. and 130.degree. C. without adding any external cooling or heating energy. Pure hydrochloric acid is recovered in an absorption zone.

    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.
