  • Patent number: 9157034
    Abstract: This invention is related to the use of ionic liquids of general formula C+A?, where C+ represents a cation of organic or inorganic type, specifically of the type imidazolium, pyridinium or ammonium salts, while the anion A? are derivatives which are halides, salts of iron (III), aluminum salts (III), acetate and benzoate, though not exclusively. These agents act as ionic liquid extractants of nitrogenous compounds present in hydrocarbon streams through a process of liquid-liquid extraction thereby can be reduced by more than 60% the content of these contaminants in hydrocarbon streams.

    Abstract: A process to prepare substantially pure glycolonitrile in an aqueous medium is provided by reacting hydrogen cyanide and formaldehyde. The formaldehyde feed stream is heated prior to reacting with hydrogen cyanide, resulting in an aqueous glycolonitrile solution with fewer impurities, especially less unreacted formaldehyde, than is obtained by other methods. The process enables production of an aqueous glycolonitrile solution that requires less post-reaction purification (if any at all) prior to enzymatically converting the glycolonitrile into glycolic acid.

The same flameproofing effect is achieved with smaller additive quantities than previously, thus reducing the influence of the physical, especially textile-physical properties of the polymers. The adducts containing poly-DOPO are formed by reacting DOPO with acetylenes carrying reactive groups, in the presence of a catalyst.
