Title: Harold Eugene Johnston: Innovator in Crystallization Processes
Introduction
Harold Eugene Johnston is a notable inventor based in Dickson, TN (US). He has made significant contributions to the field of crystallization, particularly with his innovative processes involving CL-20, a high-density explosive compound. His work has implications for both military and commercial applications.
Latest Patents
Johnston holds a patent for a process of crystallizing CL-20. This process involves drying a wet CL-20 solvent/CL-20 solution through azeotropic distillation of a CL-20 solvent/water azeotrope. By removing water from the solution, high-density CL-20 can be crystallized. The addition of a low-density CL-20 non-solvent facilitates the precipitation of the .epsilon.-polymorph CL-20. The resulting crystals are then separated from the non-solvent and solvent by adding sufficient water to displace them from the surface of the CL-20 crystals. This method ensures that the .epsilon.-polymorph CL-20 is made wet for later handling, packaging, and shipping.
