Abstract: The present invention relates to an ABS graft copolymer, a method of preparing the same, and a thermoplastic resin composition including the same. More specifically, when an ABS graft copolymer is prepared using emulsion polymerization, a phosphate ester-based reactive emulsifier capable of acting as a metal deactivator is added, thereby reducing the amount of undesired residues remaining in the ABS graft copolymer latex. As a result, thermal stability may be improved without adding a heat stabilizer. In addition, compatibility between the ABS graft copolymer and the aromatic vinyl compound-vinyl cyanide compound copolymer may be improved by the phosphate ester-based reactive emulsifier. Therefore, a final molded part having improved impact resistance, e.g., increased impact strength, and having improved appearance quality, e.g., excellent whiteness, while having excellent thermal stability may be prepared.

Abstract: Disclosed is a method of removing organic acids from crude oil using a gas hydrate inhibitor and a catalyst in crude oil production facilities or oil-refining facilities, in which organic acids can be removed from crude oil by reacting the crude oil with mono-ethylene glycol (MEG), di-ethylene glycol (DEG), tri-ethylene glycol (TEG), methanol or derivatives thereof, as a gas hydrate inhibitor in the presence of a tungstophosphoric acid (TPA) catalyst, whereby the acidity of the crude oil can be lowered by 93% or more, and no catalyst deactivation occurs because magnesium (Mg)-based catalysts are not used. Furthermore, a continuous process is achieved in such a manner that the gas hydrate inhibitor and the catalyst are not discarded but are collected from the crude oil from which organic acids have been removed, and are thus recycled, thereby realizing environmentally friendly, economical and efficient removal of organic acids from crude oil.
