    摘要： A method for the manufacture of concentrated phosphorous acid starting from pure P4O6 is disclosed. The P4O6 is hydrolysed, preferably under stirring in water in the presence of a homogeneous Broensted acid catalyst while maintaining in the hydrolysis/reaction medium a pH below 5 whereby the free water level, at the completion of the hydrolysis, is in the range from 0 to 40%.

    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 A melt is withdrawn from the first separation zone into a crystallizing zone.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.

    摘要： A process for the manufacture of an aqueous composition that is a combination of a fungicide and fertilizer comprising the following steps: (1) dissolving phosphorous acid in phosphoric acid to form a solution of an acid mixture; (2) reacting the acid mixture of step (1) with an aqueous potassium hydroxide solution at a temperature of about 65° C. to about 260° C. in a continuous reactor while maintaining the ratio of potassium to phosphorous in various mole ratios thereby forming a reaction mixture comprising potassium phosphates, potassium polyphosphates, potassium phosphites, and potassium polyphosphites and potassium phosphate phosphite copolymers; and, (3) cooling the reaction mixture rapidly at least 1° C. to 60° C., to below about 35° C. to about 65° C. Using a similar process a composition having fungicidal properties is prepared by reaction phosphoric acid with potassium hydroxide.The reaction mixtures prepared according to each of the above processes are also part of this invention.
