Abstract
Abstract A process which comprises (A) combining (i) glycerol, erythritol, arabitol, xylitol, sorbitol, dulcitol, mannitol, inositol, a monosaccharide, or a disaccharide, (ii) water and (iii) lactic acid, glycolic acid, malic acid, citric acid, tartaric acid, saccharic acid, gluconic acid, glyceric acid or mandelic acid to provide an aqueous solution of the polyol and the α-hydroxy carboxylic acid, and (B) then at an alkaline pH of 10 or less reacting the solution with a tetravalent titanium compound of an inorganic acid at an α-hydroxy carboxylic acid:titanium mol ratio between about 0.5:1 and about 4:1 and a polyol:titanium mol ratio between about 0.25:1 and about 2:1.
