Abstract: A method and system provide a complete energy analytical model. An input model is acquired and consists of a combination of architectural building elements (ABEs) and conceptual massing elements (CMEs). The input model is pre-processed by extracting information from both the ABEs and the CMEs, and constructing virtual elements that encapsulate the extracted information. A discrete set of points in three-dimensional (3D) space that is distributed over boundary faces of the ABEs or CMEs is determined. The discrete set of points is used to provide a representation of the input model that is used in combination with a 3D cubical grid (a voxel grid) to analyze a spatial structure of the input model. A two-dimensional (2D) discrete approximation of the geometry of the input model is used to determine surfaces of the energy analytical model which is then output.

Abstract: A continuous process for the production of dimethylformamide comprising the steps: (a) reacting methyl formate and dimethylamine in a reactive distillation column under conditions to form dimethylformamide and by-product methanol; (b) vaporizing the by-product methanol and generating a liquid dimethylformamide while in said reactive distillation column; (c) removing at least a major portion of the by-product methanol as an overhead from said reactive distillation column; (d) removing a crude liquid dimethylformamide containing residual by-product methanol as a bottoms fraction from said reactive distillation column; (e) introducing said bottoms fraction containing dimethylformamide and residual by-product methanol to a purification column wherein the by-product methanol is removed from said dimethylformamide as an overhead and purified dimethylformamide is removed as a bottoms fraction; and, optionally, (f) recycling the by-product methanol removed as an overhead from the purification column to the reac

Abstract: This invention relates to an improvement in a process for the production of an alkyl formamide, wherein a gas-containing carbon monoxide is reacted at elevated temperature and pressure in reaction zone with a nitrogen-containing compound selected from the group consisting of ammonia, a primary or secondary alkylamine, in the presence of a solvent and a catalyst. The improvement comprises utilizing a solvent comprising a polyethylene glycol, polypropylene glycol, polyethylenepropylene glycol, or mixtures, and an alkali metal or alkaline earth metal alkoxide of a polyethylene glycol, polypropylene glycol, polyethylenepropylene glycol or mixtures as the catalyst.

Abstract: This invention relates to an improvement in a process for the catalytic amination of an allylic alcohol of the formula:CH.sub.2 .dbd.CR--CH.sub.2 OHwhere R is hydrogen or methyl with ammonia or an amine of the formula R.sub.1 R.sub.2 NH where R.sub.1 and R.sub.2 represent hydrogen or a C.sub.1-5 hydrocarbyl group in the presence of an effective amount of a phosphorous containing catalyst to effect reaction between the allylic alcohol and the ammonia or amine to produce an allylic amine. The improvement in the process resides in utilizing a neutral group IIA metal phosphate as a catalyst component. Calcium phosphate is preferred and the catalyst.
