    摘要: A method for calculating the average molecular weight of individual molecules in a sample, where the molecules in solution associate to form clusters. Data sets of apparent molecular weight of the sample versus concentration of the sample in the solvent are generated. The basic principles and technology in generation of the data is the well understood action of a solute upon the solvent vapor pressure above the solution. By observing the effect of a sample solute on the temperature/vapor pressure properties of a solvent, it is possible by known methods to determine its molecular weight. When dealing with a solute material that tends to form clusters, however, the molecular weight found is an apparent molecular weight, i.e. the average molecular weight of all of the particles, which are the clusters and any unassociated molecules, if any. To determine the true molecular weight, a method employing the determined apparent molecular weights, referred to herein as the BRD method, is used. Since the method is based upon cluster thermodynamics and equilibrium properties, it reflects more accurately the behavior of the clusters at various dilutions. The method provides a basis for the prediction of thermodynamic and equilibrium properties, which was not possible with previous methods.

    摘要: A method for calculating the average aggregate mass of individual molecules in a sample, where the molecules in solution associate to form clusters. Data sets of average aggregate mass of the sample versus concentration of the sample in the solvent are generated.

By observing the effect of a sample solute on the temperature/vapor pressure properties of a solvent, if is possible by known methods to determine its average aggregate mass.

    摘要: A two-stage process for producing acetylene and calcium chloride from calcium carbide and water has two successive reaction steps. In step Number 1, calcium carbide is charged into an entrained flow-type reactor vessel containing water. The reaction which follows proceeds to about 60-90% completion. The entrained reaction products and the unreacted feed material are carried over to a secondary reactor to complete the reaction, and the acetylene gas is drawn off. Calcium hydroxide product is removed from the reactor and reacted with hydrogen chloride to form calcium chloride. Heat generated by the exothermic reactions of water with calcium carbide and HCl with calcium hydroxide is used to dry the calcium chloride product and improve its value. In the presence of excess water, the calcium carbide-water reaction is effectively a first order, irreversible reaction.
