  • Patent number: 4645859
    Abstract: Methods are provided for recovering purified biuret from aqueous solutions containing biuret and higher molecular weight urea condensation products by contacting such solutions with the hydroxide ion form of an anion exchanger and extracting biuret from the ion exchanger with an aqueous extractant. The useful biuret-containing solutions also may contain urea. These methods are capable of recovering biuret of 99.9 percent plus purity from solutions containing higher molecular weight urea condensations products such as triuret, melamine, ammelide, and others. Elevated temperatures increase biuret recovery rate and concentration, and the extractant can be recycled into contact with additional biuret-containing anion exchangers to increase biuret concentration even further. The biuret-containing extract can be employed as is, concentrated by evaporation or otherwise, or treated to crystallize biuret.

  • Patent number: 4623489
    Abstract: A method of refining edible oil which protects the oil from auto-oxidation and hydrolysis. The method of refining is of the type which includes a degumming stage where acid-water are blended with the oil to capture phosphatides in the oil and then separated from the oil to carry away the phosphatides. The method comprises deaerating the acid-water prior to blending with the oil so that as the acid-water removes phosphatides it also removes oxygen from the oil. Subsequent to the degumming stage, it is preferable that the processed oil be protected against any further contact with oxygen or water. If it is desired to remove all traces of oxygen an oxygen scavenger such as sodium sulfite can be added to the acid-water used in degumming.
