Method of preparing heteropoly compounds

Claim 1

THE METHOD OF PREPARING HETEROPOLYTUNGSTIC AND HETEROPOLYMOLYBDIC ACIDS AND AMMONIUM SALTS OF THE SAID ACIDS, THE HETEROATOM IN THE SAID ACIDS AND SALTS BEING SELECTED FROM GROUP (A) CONSISTING OF SILICON, ALUMINUM, VANADIUM, TITANIUM, IRON, NICKEL, COBALT, ANTIMONY, NIOBIUM, GERMANIUM, TIN AND CERIUM WHEN THE HETEROPOLY COMPOUND IS HETEROPOLYTUNGSTIC ACID OR HETEROPOLYMOLYBDIC ACID, AND BEING SELECTED FROM THE GROUP CONSISTING OF (B) THE AFOREMENTIONED HERETOATOMS OF GROUP (A) AND, IN ADDITION, ARSENIC, BORON, AND PHOSPHORUS WHEN THE HETEROPOLY COMPOUND IS AN AMMONIUM SALT OF THE AFORESAID HETEROPOLY ACIDS, SAID METHOD COMPRISING DIRECTLY INTRODUCING THE HETEROATOM INTO THE CONDENSED OXIDE STRUCTURE OF A NONHETEROPOLYTUNGSTIC OR A NONHETEROPOLYMOLYBDIC ACID OR AN AMMONIUM SALT THEREOF BY CONTACTING, IN AQUEOUS MEDIUM AND AT A TEMPERATURE WITHIN THE RANGE OF FROM ABOUT 20*C. TO ABOUT 100*C., (A) A COMPOUND OF THE GROUP CONSISTING OF A POLYTUNGSTIC ACID, A POLYMOLYBDIC ACID, AND THE AMMONIUM SALTS OF THE SAID ACIDS, SAID ACIDS AND SALTS BEING WATER-SOLUBLE AND HAVING A CONDENSED OXIDE POLYHEDRAL STRUCTURE, WITH (B) A SUBSTANCE OF THE GROUP CONSISTING OF ELEMENTAL METALS, OXIDES AND ACIDS OF ELEMENTAL METALS, AND HYDROLYZABLE ORGANOMETALLIC COMPOUNDS, THE SAID SUBSTANCE HAVING A HETEROATOM OF THE AFORESAID GROUP (A) WHEN THE HETEROPOLY COMPOUND TO BE PRODUCED IS HETEROPOLYTUNGSTIC ACID OR HETEROPOLYMOLYBDIC ACID, AND HAVING A HETEROATOM OF GROUP (B) WHEN THE HETEROPOLY COMPOUND TO BE PRODUCED IS AN AMMONIUM SALT OF THE AFORESAID HETEROPOLY ACIDS, THE AMOUNT OF THE SUBSTANCE OF (B) IN THE SAID AQUEOUS MEDIUM BEING SUFFICIENT TO PROVIDE AT LEAST 0.5 GRAM ATOM OF THE AFORESAID HETEROATOM FOR EACH 12 GRAM ATOMS OF TUNGSTEN OR MOLYBDENUM IN THE TUNGSTEN OR MOLYBDENUM COMPOUNDS OF (A).

Claim 2

THE METHOD OF PREPARING HETEROPOLYTUNGSTIC AND HETEROPOLYMOLYBDIC ACIDS AND AMMONIUM SALTS OF THE SAID ACIDS, THE HETEROATOM IN THE SAID ACIDS AND SALTS BEING SELECTED FROM GROUP (A) CONSISTING OF SILICON, ALUMINUM, VANADIUM, TITANIUM, IRON, NICKEL, COBALT, ANTIMONY, NIOBIUM, GERMANIUM, TIN AND CERIUM WHEN THE HETEROPOLY COMPOUND IS HETEROPOLYTUNGSTIC ACID OR HETEROPOLYMOLYBDIC ACID, AND BEING SELECTED FROM THE GROUP CONSISTING OF (B) THE AFOREMENTIONED HERETOATOMS OF GROUP (A) AND, IN ADDITION, ARSENIC, BORON, AND PHOSPHORUS WHEN THE HETEROPOLY COMPOUND IS AN AMMONIUM SALT OF THE AFORESAID HETEROPOLY ACIDS, SAID METHOD COMPRISING DIRECTLY INTRODUCING THE HETEROATOM INTO THE CONDENSED OXIDE STRUCTURE OF A NONHETEROPOLYTUNGSTIC OR A NONHETEROPOLYMOLYBDIC ACID OR AN AMMONIUM SALT THEREOF BY CONTACTING, IN AQUEOUS MEDIUM AND AT A TEMPERATURE WITHIN THE RANGE OF FROM ABOUT 20*C. TO ABOUT 100*C., (A) A COMPOUND OF THE GROUP CONSISTING OF A POLYTUNGSTIC ACID, A POLYMOLYBDIC ACID, AND THE AMMONIUM SALTS OF THE SAID ACIDS, SAID ACIDS AND SALTS BEING WATER-SOLUBLE AND HAVING A CONDENSED OXIDE POLYHEDRAL STRUCTURE, WITH (B) A SUBSTANCE OF THE GROUP CONSISTING OF ELEMENTAL METALS, OXIDES AND ACIDS OF ELEMENTAL METALS, AND HYDROLYZABLE ORGANOMETALLIC COMPOUNDS, THE SAID SUBSTANCE HAVING A HETEROATOM OF THE AFORESAID GROUP (A) WHEN THE HETEROPOLY COMPOUND TO BE PRODUCED IS HETEROPOLYTUNGSTIC ACID OR HETEROPOLYMOLYBDIC ACID, AND HAVING A HETEROATOM OF GROUP (B) WHEN THE HETEROPOLY COMPOUND TO BE PRODUCED IS AN AMMONIUM SALT OF THE AFORESAID HETEROPOLY ACIDS, THE AMOUNT OF THE SUBSTANCE OF (B) IN THE SAID AQUEOUS MEDIUM BEING SUFFICIENT TO PROVIDE AT LEAST 0.5 GRAM ATOM OF THE AFORESAID HETEROATOM FOR EACH 12 GRAM ATOMS OF TUNGSTEN OR MOLYBDENUM IN THE TUNGSTEN OR MOLYBDENUM COMPOUNDS OF (A).
