Novel Organic Corrosion Inhibitors for Steel

51008-98-I Novel Organic Corrosion Inhibitors for Steel--TDA Research, Inc., 12345 West 52nd Avenue, Wheat Ridge, CO 80033-1916; (303) 940-2300 Dr. Bryan M. Smith, Principal Investigator Mr. John D. Wright, Business Official DOE Grant No. DE-FG03-98ER82690 Amount: $75,000 Advanced energy efficient heat transfer cycles for heating, ventilation and air conditioning (HVAC) systems employ corrosive working fluids. To make these processes economically competitive with traditional HVAC systems, the corrosion must be controlled. In this project, novel organic inhibitors will be developed to prevent the corrosion of steel in aqueous potassium acetate. After initial synthesis and testing of the proposed materials, additional inhibitor candidates will be identified based on a integrated approach combining molecular modeling and experimental electrochemistry. In Phase I, several corrosion inhibitors will be prepared from inexpensive starting materials and their anti-corrosion properties will be tested by electrochemical methods. Concurrently, molecular modeling using commercial software will allow identification of the critical molecular properties which control inhibitor performance. Commercial Applications and Other Benefits as described by the awardee: The development of these additives would allow HVAC systems based on energy efficient advanced absorption cycles to compete with conventional heating and cooling systems. These new corrosion inhibitors would also find acceptance wherever steel surfaces are exposed to a corrosive environment, and may inhibit the corrosion of other metals as well._
