Process of decreasing the salt content of an acidic silica hydro-organosol

Claim 2

A PROCESS OF DECREASING THE SALT CONTENT OF AN ACIDIC SILICA HYDRO-ORGANOSOL WHICH COMPRISES CONTACTING AT A TEMPERATURE BELOW 30*C. AN ACIDIC SILICA HYDROORGANOSOL CONTAINING WATER, FROM ABOUT 5 TO 12% BY WEIGHT OF SILICA AS SILICA ACID FROM ABOUT 25 TO 60% BY WEIGHT OF A SUNSTANTIALLY NEUTRAL WATER-MISCIBLE ORGANIC LIQUID CONSISTING OF CARBON, HYDROGEN AND OXYGEN ATOMS, AT LEAST 0.1% BY WEIGHT OF A SALT OF A MINERAL ACID AND A WATER-SOLUBLE ALKALI SILICATE AND A MINERAL ACID IN AN AMOUNT SUFFICIENT TO PROVIDE A PH OF 1.8 TO 4.5, WITH THE HYDROGEN FORM OF A WATER-INSOLUBLE STRONG CATION-EXCHANGE MATERIAL AND THE SULFATE FORM OF A WATER-INSOLUBLE ANION-EXCHANGE MATERIAL CONTAINING SALT-FORMING NITROGEN ATOMS, UNTIL THE HYDRO-ORGANOSOL CONTAINS LESS THAN 0.05% BY WEIGHT OF SAID SALT, SAID HYDRO-ORGANOSOL BEING REMOVED FROM CONTACT WITH SAID ANION-EXCHANGE MATERIAL BEFORE THE PH OF THE SDOL EXCEEDS 4.5.

Claim 3

A PROCESS OF DECREASING THE SALLT CONTENT OF AN ACIDIC HYDRO-ORGANOSOL WHICH COMPRISES CONTACTING AT A TEMPERATURE BELOW 30*C. AN ACIDIC HYDRO-ORGANOSOL CONTAINING WATER, FROM ABOUT 5 TO 12% BY WEIGHT OF SILICA AS SILICIC ACID, FROM ABOUT 25 TO 60% BY WEIGHT OF A SUBSTANTIALLY NEUTRAL WATER-MISCIBLE ORGANIC LIQUID CONSISTING OF CARBON, OXYGEN AND HYDROGEN ATOMS, AT LEAST 0.1% BY WEIGHT OF SALT OF A MINERAL ACID AND AN ALKALI SILICATE AND A MINERAL ACID IN AN AMOUNT SUFFICIENT TO PROVIDE A PH OF 1.8 TO 4.5 WITH THE HYDROGEN FORM OF A WATER-INSOLUBLE STRONG CATION-EXCHANGE MATERIAL AND THE SULFATE FORM OF A WATERINSOLUBLE ANION-EXCHANGE MATERIAL CONTAINING SALT-FORMING NITROGEN ATOMS, UNTIL THE HYDRO-ORGANOSOL CONTAINS LESS THAN 0.025% BY WEIGHT OF SAID SALT, SAID HYDRO-ORGANOSOL BEING REMOVED FROM CONTACT WITH SAID ANION-EXCHANGE MATERIAL BEFORE THE PH OF THE SOL EXCEEDS 4.5 TREATING THE RESULTING ANION-EXCHANGE MATERIAL WITH WATER UNTIL IT IS REGENERATED TO THE SURFATE FORM AND TREATING THE CATIONEXCHANGE MATERIAL WITH THE RESULTING WATER TO AT LEAST PARTIALLY REGENERATE SAID CATION-EXCHANGE MATERIAL TO THE HYDROGEN FORM AND THEREAFTER CONTACTING ADDITIONAL QUANTITIES OF SAID FIRST MENTIONED ACIDIC SILICA HYDRO-ORGANOSOL WITH SAID REGENERATED, CATION-EXCHANGE MATERIAL AND SAID REGENERATED ANION-EXCHANGE MATERIAL IN ACCORDANCE WITH THE AFOREDESCRIBED PROCESS.

Claim 4

A PROCESS OF DECREASING THE SALLT CONTENT OF AN ACIDIC HYDRO-ORGANOSOL WHICH COMPRISES CONTACTING AT A TEMPERATURE BELOW 30*C. AN ACIDIC HYDRO-ORGANOSOL CONTAINING WATER, FROM ABOUT 5 TO 12% BY WEIGHT OF SILICA AS SILICIC ACID, FROM ABOUT 25 TO 60% BY WEIGHT OF A SUBSTANTIALLY NEUTRAL WATER-MISCIBLE ORGANIC LIQUID CONSISTING OF CARBON, OXYGEN AND HYDROGEN ATOMS, AT LEAST 0.1% BY WEIGHT OF SALT OF A MINERAL ACID AND AN ALKALI SILICATE AND A MINERAL ACID IN AN AMOUNT SUFFICIENT TO PROVIDE A PH OF 1.8 TO 4.5 WITH THE HYDROGEN FORM OF A WATER-INSOLUBLE STRONG CATION-EXCHANGE MATERIAL AND THE SULFATE FORM OF A WATERINSOLUBLE ANION-EXCHANGE MATERIAL CONTAINING SALT-FORMING NITROGEN ATOMS, UNTIL THE HYDRO-ORGANOSOL CONTAINS LESS THAN 0.025% BY WEIGHT OF SAID SALT, SAID HYDRO-ORGANOSOL BEING REMOVED FROM CONTACT WITH SAID ANION-EXCHANGE MATERIAL BEFORE THE PH OF THE SOL EXCEEDS 4.5 TREATING THE RESULTING ANION-EXCHANGE MATERIAL WITH WATER UNTIL IT IS REGENERATED TO THE SURFATE FORM AND TREATING THE CATIONEXCHANGE MATERIAL WITH THE RESULTING WATER TO AT LEAST PARTIALLY REGENERATE SAID CATION-EXCHANGE MATERIAL TO THE HYDROGEN FORM AND THEREAFTER CONTACTING ADDITIONAL QUANTITIES OF SAID FIRST MENTIONED ACIDIC SILICA HYDRO-ORGANOSOL WITH SAID REGENERATED, CATION-EXCHANGE MATERIAL AND SAID REGENERATED ANION-EXCHANGE MATERIAL IN ACCORDANCE WITH THE AFOREDESCRIBED PROCESS.
