Stable dispersions of colloidal sulfur, processes of preparing same, and sulfur solutions adapted for use in preparing such dispersions

Claim 1

THE PROCESS OF PREPARING A STABLE DISPERSION OF COLLODIAL SULFUR AT AN ELEVATED TEMPERATURE WITHIN THE RANGE OF FROM 100* TO 140*C., WHICH PROCESS COMPRISES DISSOLVING SULFUR AT A TEMPERATURE WITHIN SAID RANGE IN A SOLVENT FROM THE GROUP CONSISTING OF (A) ALIPHATIC POLY ALCOHOLS HAVING FROM 2 TO 3 HYDROXY GROUPS, CONTAINING FROM 2 TO 1,000 CARBON ATOMS AND HAVING ALL OF THE HYDROXY GROUPS FREE; (B) SAID ALCOHOLS IN WHICH ONE OF THE HYDROXY GROUPS IS ESTERFIFED BY A FATTY ACID CONTAINING FROM 10 TO 22 CARBON ATOMS; (C) SAID ALCOHOLS IN WHICH ONE OF THE HYDROXY GROUPS IS ETHERIFIED, THE ETHER RADICAL BEING FROM THE GROUP CONSISTING OF ALKYL CONTAINING NOT MORE THAN 2 CARBON ATOMS, ALKYLHDROXY CONTAINING FROM 1 TO 6 CARBON ATOMS AND ESTERFIED ALKYLHYDROXY GROUPS IN WHICH THE ESTER PORTION IS DERIVED FROM A FATTY ACID CONTAINING FROM 10 TO 22 CARBON ATOMS AND THE ALKYL GROUP CONTAINS FROM 1 TO 6 CARBON ATOMS; (D) ALIPHATIC POLY ALCOHOLS HAVING 3 HYDROXY GROUPS, CONTAINING FROM 3 TO 1,000 CARBON ATOMS IN WHICH TWO OF THE HYDROXY GROUPS ARE ESTERFIED BY FATY ACIDS CONTAINING FROM 10 TO 22 CARBON ATOMS AND THE THIRD HYDROXY GROUP IS FREE; AND HYDROXY GROUP IS ETHERFIED, THE ETHER RADICAL BEING FROM THE GROUP CONSISTING OF ALKYL CONTAINING NOT MORE THAN 2 CARBON ATOMS, ALKHYDROXY CONTANING FROM 1 TO 6 CARBON ATOMS AND ESTERIFIED ALKYLHYDROXY GROUPS IN WHICH THE ESTER PORTION IS DERIVED FROM A FATTY ACID CONTAINING FROM 10 TO 22 CARBON ATOMS AND ANOTHER HYDROXY GROUP IS ESTERFIED WITH A FATTY ACID CONTAINING FROM 10 TO 22 CARBON ATOMS THE THIRD HYDROXY GROUP BEING FREE, AND ADDING THE RESULTANT SULFUR SOLUTION TO A VEHICLE FROM THE GROUP CONSISTING OF WATER, FAT AND OIL IN WHICH THE SULFUR IS INSOLUBLE BUT WITH WHICH THE SOLVENT IS FREELY MISCIBLE.
