Anticipating the increased reliance on low-reactivity solvents for consumer-based products, the properties of existing and emerging solvents and solvent mixtures were investigated. A compilation of these properties, arranged into a database, was intended to facilitate the comparison of products for alternative lower reactive formulations for consumer products. Solvents for inclusion in the database were selected in accordance with program objectives of the Air Resources Board (ARB). The end-product of this phase of the work was a database of physical and chemical properties for selected solvents and solvent mixtures. This database will be made available for use by the public.
In a separate task not related to the database, the species profiles for a number of selected hydrocarbon solvent mixtures were determined. Analysis of these materials was performed using high-resolution capillary gas chromatography. Detection was by flame ionization detector, and/or mass selective detector, as deemed necessary for identification and quantitation of the sample components. The analytical methods identified and quantified VOCs present in common hydrocarbon solvent mixtures used in consumer products.
Albert Censullo is currently a Professor in the Department of Chemistry and Biochemistry at Cal Poly State University, San Luis Obispo, where he has been employed since 1974. He served as Department Chair from 1995-1999. He holds a Ph.D. in Analytical Chemistry from Pennsylvania State University.
He has been involved in a number of ARB-sponsored projects dealing with the determination of species profiles, for source categories that have included fugitive emissions from oil production, small engines, architectural coatings, and aerosol coatings. He has served as instructor for a number of Air Pollution Training Institute (APTI) courses held annually at Cal Poly.
