Investigation of potential replacement solvents for 1,1,1-trichloroethane for cold cleaning of electrical apparatus

Abstract

1, 1, I-trichloroethane, otherwise known as methyl chloroform or TCA, is a chlorinated hydrocarbon that has been identified as an ozone depleting substance (ODS) by the United States Environmental Protection Agency (EPA). As of January 1, 1996, it was phased out of production. This chemical was the most widely used cold cleaning solvent for electrical apparatus. Thus, alternatives are needed. This project focused on investigating environmentally friendly alternative solvents as potential replacements for TCA. A number of solvents from the ones studied were identified as possible alternatives: Electron, Positron, Electron QED, and Prepsolv from Ecolink; PF Degreaser from P-T Technologies; Axarel 6100 from Petroferm; and Stoddard Solvent, Decane and n-Dodecane from Fisher Scientific. Due to the relatively low flash points of Electron QED, Prepsolv, Stoddard Solvent, and Decane, it is recommended that these solvents be limited to cold cleaning applications that utilize small volumes, such as hand wiping. The testing methodology, results and discussion, conclusions, and recommendations are presented.
