    Abstract: Phosphorus-containing compounds, especially alkyl phosphates, of the formula
    wherein A is oxygen or sulfur, g and n are 0 or 1, and R1, R2 and R3, which may be the same or different, are alkyl, cycloalkyl or aryl wherein R1 may be substituted with one or more halogen atoms; are formed from the corresponding halo- or halo-alkoxyphosphorus compounds and a hydroxy-containing organic compound by reaction therebetween under gradual increase of temperature and simultaneous decrease in pressure, over an organo oxy compound catalyst comprising an element of Group II, IV or V of the Periodic System having an atomic number of between 12 and 83, in amounts of from 0.001 to 2 per cent by weight, based on the amount of starting phosphorus compound reactant.

    Abstract translation: 含有磷的化合物，特别是烷基磷酸酯，其通式为R 1 - （O）n | R2-O-P =（A）q | R3-O其中A为氧或硫，g和n为0或 1，R 1，R 2和R 3可以相同或不同，为烷基，环烷基或芳基，其中R 1可被一个或多个卤素原子取代; 由相应的卤代或卤代 - 烷氧基 - 磷化合物和含羟基的有机化合物通过在逐渐升高的温度下同时降低压力而相对于包含II，IV族元素的有机氧化合物催化剂而形成， 基于起始磷化合物反应物的量，周期性体系的V为原子序数为12至83，其量为0.001至2重量％。

    CPC classification number: C01G31/04

    Abstract: IN THE PRODUCTION OF VANADIUM OXYTRICHLORIDE WHEREIN VANADIUM PENTOXID, CARBON AND CHLORINE ARE REACTED, THE IMPROVEMENT WHICH COMPRISES EFFECTING THE REACTION BY CONTACTING A MIXTURE OF FINE-GRAINED VANADIUM PENTOXIDE AND CARBON IN THE FORM OF A GAS PERMEABLE LAYER ABOUT 0.5 TO 20 CM. HIGH WITH CHLORINE AT A TEMPERATURE OF ABOUT 350 TO 750*C. PREFERABLY THE PROCESS IS CARRIED OUT CONTINUOUSLY AND THE REACTION TEMPERATURE IS MAINTAINED AND CONTROLLED BY REGULATING THE RATE OF ADDITION OF THE REACTANTS. THE RESULTING VANADIUM OXYTRICHLORIDE IS VOLATILIZED AT A TEMPERATURE OF ABOUT 150*C. AND IS THEREAFTER CONDENSED.
