摘要： The purification of phosphorous acid which is formed in halogenations of hydrocarbon derivatives using phosphorus trihalides is carried out in the context of preparing phosphorous acid in a reaction zone by reacting a mixture of phosphorus trichloride and water which has been finely divided by means of steam at temperatures between 150.degree. and 200.degree. C. in the gas phase. In this process, the liquid reaction product drains into a concentrating evaporation zone which has a downstream first separation zone. Inert gas is introduced to the lower part of the first separation zone. A melt is withdrawn from the first separation zone into a crystallizing zone. The waste gases from the reaction zone are treated with a washing liquid in a second separation zone before being passed into the atmosphere. The washing liquid used is an aqueous solution of never-purified phosphorous acid, which can have been prepurified by hydrolysis and stripping.

摘要： Phosphorous acid is produced from PCl.sub.3 and water in an apparatus, the essential parts of which include a reactor and an evaporator, which are connected together by means of a conduit running from the bottom of the reactor to the head of the evaporator. The evaporator communicates with the lower end of a separator of which the upstream end terminates in an off-gas outlet. More particularly, the downstream end of the evaporator is connected to a stripping column which is provided with an off-gas outlet opening into the off-gas outlet associated with the evaporator.
