Reaction Conditions

Reaction Steps

Lactic acid (226.8 g, 2.52 mol) was dissolved in hot water (371 g) in a flask of 3 L having an agitator, a condenser and a thermometer. Titanium tetraisopropoxide (285 g, 1.00 mol) was slowly added to this solution being agitated, from a drop funnel. This mixture was heated and circulated for one hour to prepare a cloud solution, and by this, isopropanol/water mixture was distilled under a pressure-reduced condition. The product was cooled down to a temperature lower than 70° C., and then, aqueous solution containing NaOH (380 g, 3.04 mol) at 32% by weight was slowly added to this solution being agitated, from a drop funnel. The obtained product was filtered, then mixed with ethylene glycol (504 g, 8 mol), thereafter heated under a pressure-reduced condition to remove isopropanol/water, and a slightly cloud light yellow product (Ti content: 5.6% by weight) was obtained (titanium lactate sodium chelate compound).
