IR peaks in the ranges of 1700 and 1740 [cm.sup.-1] were examined to differentiate absorbance peaks due to cellulose esterification from those indicative of triglyceride esters, carboxylic acids, and amide carbonyl groups (per the reaction of diacids in the presence of ammonium hydroxide (7)).
du Pont de Nemours and Company has obtained a patent for a process comprised of digesting ilmenite ore with aqueous ammonium hydrogen oxalate to form a leachate and a precipitate comprised of FeC2O4.2H20; separating the leachate from the precipitate comprised of FeC2O4.2H20; hydrolyzing the leachate with ammonia or ammonium hydroxide to form titanyl hydroxide and an oxalate-rich solution; separating the titanyl hydroxide from the oxalate-rich solution; washing the titanyl hydroxide with a material selected from the group consisting of water, aqueous ammonium oxalate and ammonium hydroxide to form low oxalate titanyl hydroxide, that is, titanyl hydroxide that is stripped of residual oxalate; and crystallizing titanium dioxide from the low oxalate titanyl hydroxide.
