Reducing aluminosilicate scale in the bayer process

A method for the reduction of aluminosilicate containing scale in a Bayer process comprising the steps of:

• adding to the Bayer process stream an aluminosilicate scale inhibiting amount of a composition comprising at least one small molecule, the at least one small molecule comprising of at least three components, one being an R1 component, one being an R2 component and one being an R3 component, the components within the small molecule arranged according to the general formula:
• wherein the small molecule may be at least one of carbonates, bicarbonates, carbamates, ureas, amides and salts thereof and:
• R1 is selected from the group consisting of:
• H, alkyl, amine, structure (A) and structure (B);
• R2 is independently selected from the group consisting of:
• H, alkyl, amine, G and E,
• G being one item selected from the group consisting of:
• 3-glycidoxypropyltrimethoxysilane, 3-glycidoxypropyltrialkoxysilane, 3-glycidoxypropylalkyldialkoxysilane, 3-glycidoxypropyldialkylmonoalkoxysilane, 3 isocyanatopropyltrialkoxysilane, 3-isocyanatopropylalkyldialkoxysilane, 3-isocyanatopropyldialkylmonoalkoxysilane, 3-chloropropyltrialkoxysilane, 3-chloropropylalkyldialkoxysilane, and 3-chloropropyldialkylmonoalkoxysilane and wherein G is optionally hydrolyzed;
• E being 2-ethylhexyl glycidyl ether, C3-C22 glycidyl ether, C3-C22 isocyanate, C3-C22 chloride, C3-C22 bromide, C3-C22 iodide, C3-C22 sulfate ester, C3-C22 phenolglycidyl ether, and any combination thereof,
• R3 is independently selected from the group consisting of:
• H, alkyl, amine, G and E and
• n is an integer from 2 to 6.
