Title: Process for the preparation of optically monoesters derivative from alkanolamines and tartaric acid
IPC: C07C219/20
Filed: 1984-08-08
Abstract: For the analytical and preparative separation of the optical isomers of optically active alkanolamines into their optically pure antipodes a new resolution method is presented which involves an ester formation of the alkanolamines with optically pure and symmetrically O,O disubstituted (R,R)- or (S,S)-tartaric acids. The derivitization reactions are carried out in aprotic solvents and the primary and secondary functions are blocked via ion-pair formations with strong acids, e.g. dichloroacetic acid. The tartaric acid anhydrides are predominantly used as reagents but other ester formation methods are also practicable. The mixture of the diastereomeric alkanolamine tartaric acid monoesters are separable into their optically active and pure isomers by various chromotographic separation techniques, e.g. straight or reverse phase LC, but also by extraction methods e.g. Soxhlet extraction. The optically pure parent alkanolamine isomers can be obtained by ester hydrolysis, with high yield, from the optically pure fractions of the alkanolamine tartaric acid monoesters.

Abstract: The present invention is a chewing gum base composition and a method for making same which includes an elastomer and a resin prepared in the absence of rosin esters and terpene components which includes an elastomer component raised to a compatibilization temperature for addition of a compatibilization component. The composition includes a high melting point compatibilization component added under low shear mixing conditions at a temperature sufficient to masticate the elastomer for forming a substan­tially homogeneous mass with the resin component. The compatibilization component is capable of effectuating dissociation of the elastomer under the conditions of temperature and mixing for forming the substantially homo­geneous mass. Finally, a resin component is added also under low shear mixing conditions and mildly elevated temperatures until a substantially homogenous gum base mass is formed.

Abstract: A dry ash handling system having an ash hopper with a vertical ash pile therein allows continued and complete combustion of unburned embers before leaving the bottom of the hopper (30). A hopper air injection system (56, 60, 62, 64 and 66) forces air through the hot ash from below the top of the ash pile, increasing burn-out efficiency. The air rising through the hot ash returns residual heat to the boiler increasing efficiency, while cooling the ash to a safe handling temperature. Recirculating and adding cool fresh air enhances cooling and prevents dust from escaping. Opposed sloped sides (67 and 69) on the hopper (30) cause the ash to mix as it travels to the bottom to prevent air channelling.

Abstract: In the production of combustible gases from hydrocarbons by a partial combustion process, a portion of the product gases is continuously recycled through a conduit to the gasification zone, entering at or near the hydrocarbon inlet, and an oxygen-rich gas is admitted to the conduit for admixture with the recycled portion. The portion may amount to 10 to 80% by volume of the product gas, and the product gas may preheat the O2-rich gas, before purification and cooling which may be, e.g., in a waste heat boiler.  The product gas may be carburetted with a petroleum fuel, e.g. the one being gasified, or with propane or butane.  The delivery of the O2-rich gas to the recycled gas, and the delivery of recycled gas to the gasifier, are controlled respectively by valves, see Fig. 4 (not shown), which are controlled by devices on the feedstock line, O2-rich gas line, and recycled gas line, and the O2-rich gas may be apportioned between the recycle line and a burner for the product gas.
