A method is described for separating COand/or HS from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO. The solution containing the absorbed COcan then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO(advantageously at &#x3c;100&#xb0; C.). Upon COrelease, the regenerated lean solution can be recycled to the sorption tower. CO:(primary+secondary amine) adsorption molar ratios&#x3e;0.5:1 (approaching 1:1) may be achieved.

Provided is a process for making non-phthalate plasticizers, by acylating an aromatic compound with a succinic anhydride to form a keto-acid, and then esterifying the keto-acid with C-COXO-alcohols to form a plasticizer compound. The aromatic rings of the aromatic compound may also be optionally hydrogenated.

Ionic liquids are capable of acting as solvents for amine COabsorbent compounds in COseparation processes and when so used enhance the sorption of the COby the amine. A cyclic sorption process for separating COfrom a gas stream, such as flue gas or natural gas, brings the gas stream into contact with an absorbent solution of an amine COsorbent in an ionic liquid solvent followed by desorbing the COto regenerate the amine.

Ionic liquids as amine promoter solvents for removal of carbon dioxide

Ionic liquids containing a cation with a potentially nucleophilic carbon atom bearing a relatively acidic hydrogen atom bonded to a potentially nucleophilic carbon atom, typically in the conjugated &#x2014;NC(H)N&#x2014; structure or a &#x2014;NC(H)S&#x2014; structure of imidazolium, imidazolidinium or thiazolium salts, can be capable of acting as sorbents for COin cyclic separation processes. The ionic liquid may be used on its own, mixed with a solvent, preferably an aprotic, polar, non-aqueous solvent such as toluene, DMSO, NMP or sulfolane, or in conjunction with a non-nucleophilic nitrogenous base promoter compound having a pKof at least 10.0 such as a carboxamidine or a guanidine.

A COamine scrubbing process uses an absorbent mixture consisting of an alkanolamine COsorbent in combination with a non-nucleophilic base. The alkanolamine has oxygen and nitrogen sites capable of nucleophilic attack at the COcarbon atom. The nucleophilic addition is promoted in the presence of the non-nucleophilic, relatively stronger base, acting as a proton acceptor. The non-nucleophilic base promoter, which may also act as a solvent for the alkanolamine, can promote reaction with the COat each of the reactive hydroxyl and nucleophilic amine group(s) of the alkanolamines. In the case of primary amino alkanolamines the COmay be taken up by a double carboxylation reaction in which two moles of COare taken up by the reacting primary amine groups.

A COamine scrubbing process uses an absorbent mixture combination of an amine containing a primary amino group COsorbent in combination with a non-nucleophilic relatively stronger base. The weaker base(s) are nucleophilic and have the ability to react directly with the COin the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the COand the weaker base. Two moles of COcan be taken up by the primary amine groups in a dicarboxylation reaction, affording the potential for a highly efficient scrubbing process.

Disclosed is the preparation of compositions which are blends of certain types of hydrogenated ethylene-dicyclopentadiene (E/DCPD) copolymers in combination with elastomeric polymers. An E/DCPD copolymer and an elastomeric polymer are co-dissolved in a common liquid reaction medium which is then subjected to hydrogenation conditions. These hydrogenation conditions serve to hydrogenate in-situ at least a portion of the residual double bonds of the E/DCPD copolymer component and possibly also eliminate any residual unsaturation which might be present in the elastomeric polymers. This combination of materials which has been hydrogenated in-situ can then be co-precipitated to form a polymer composition which can be molded into polyolefin materials of improved structural, thermal and mechanical properties with desirable impact resistance.

A COamine scrubbing process uses an absorbent mixture combination of an amine COsorbent in combination with a non-nucleophilic, relatively stronger, typically nitrogenous, base. The weaker base(s) are nucleophilic and have the ability to react directly with the COin the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the COand the weaker base. The sorption and desorption temperatures can be varied by selection of the amine/base combination, permitting effective sorption temperatures of 70 to 90&#xb0; C., favorable to scrubbing flue gas.
