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

Claim 1

A PROCESS OF DECREASING THE SALT CONTENT OF AN ACIDIC SILICA HYDRO-ORGANOSOL CONTAINING A SALT OF A MINERAL ACID AND A WATER SOLUBLE ALKALI SILICATE WHICH COMPRISES CONTACTING AT A TEMPERATURE BELOW 30*C. AN ACIDIC SILICA HYDRO-ORGANOSOL CONTAINING FROM ABOUT 5 TO 11% BY WEIGHT OF SILICA, WATER, FROM ABOUT 25 TO 60% BY WEIGHT OF A SUBSTANTIALLY NEUTRAL WATER-MISCIBLE ORGANIC LIQUID CONSISTING OF CARBON, OXYEN AND HYDROGEN ATOMS, AT LEAST 0.1% BY WEIGHT OF A SALT OF A MINERAL ACID AND A WATERSOLUBLE ALKALI SILICATE AND A MINERAL ACID IN AN AMOUNT SUFFICIENT TO PROVIDE A PH OF 1.8 TO 4.0, WITH THE HYDROGEN FORM OF A WATER-INSOLUBLE, STRONG CATION-EXCHANGE MATERIAL AND A WATER-INSOLUBLE SALT OF A VOLATILE ORGANIC ACID SELECTED FROM THE GROUP CONSISTING OF FORMIC AND ACETIC ACIDS AND A WATER-INSOLUBLE, WEAK ANION-EXCHANGE MATERIAL CONTAINING A PLURALITY OF SALT-FORMING NITROGEN ATOMS, UNTIL SAID HYDRO-ORGANOSOL CONTAINS LESS THAN 0.05% BY WEIGHT OF SAID SALT OF A MINERAL ACID AND A WATER SOLUBLE ALKALI SILICATE, SAID ION-EXCHANGE MATERIALS BEING EMPLOYED IN ANY DESIRED SEQUENCE, SAID SILICA HYDROORGANOSOL BEING REMOVED FROM CONTACT WITH SAID ANIONEXCHANGE MATERIAL BEFORE THE PH OF THE HYDRO-ORGANOSOL EXCEEDS ABOUT 4.8.
