Synthesis of Polyacetylene Curing Agents

"This proposal will reveal facile synthetic procedures to safely make Compound 1, 1,4-bis(cyanoethynyl)benzene; Compound 2, dipropargylterephthalate; Compound 3, tripropargylmesitylate; and Compound 4, dodecane-2,11-dione-1,12-dipropiolate and to proposethat Dimension Technology Chemical Systems, Inc., prepare Compounds 1 through 4 in 450 gram quantities for the Naval Air Warfare Center, Weapons Division. In addition to having the required quantities of materials to advance the propellant gumstockstudies by the Navy, the results of this effort will define chemical processing methods that will have the following chemical processing attributes: (1) High Yield; (2) High Quality; (3) Acceptable Safety Risks in Processing; (4) Scalable to Product PlantEquipment; (5) High Chemical Integrity (No quality surprises on scale-up to plant equipment) and (6) Cost effective. Implementation of the technology revealed in this proposal will shorten the time necessary to scale-up chemical manufacturing procedures topilot or production plant equipment. Because of the simplicity of the recommended processes to make Compounds 1 through 4, the Phase II developmental research cost will be significantly lower and there will be a greater opportunity for a larger number ofchemical companies to compete for the production of these materials."
