Project at a Glance

Title: Investigation of low reactivity solvents

Principal Investigator / Author(s): Censullo, Albert C.

Contractor: California Polytechnic University

Contract Number: 98-310

Research Program Area: Emissions Monitoring & Control

Topic Areas: Area Sources, Stationary Sources, Toxic Air Contaminants


The contractor prepared a database of solvent properties designed to facilitate the production of 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. Special attention was given to low reactivity solvents, in support of the ARB's reactivity-based regulation for aerosol coatings. Consideration was given to solvents that are representative of those used for products formulated for the California marketplace. Supplemental information on chemical composition was obtained for all solvent and solvent mixtures studied. The database will be accessible on the World Wide Web for use by the public.

In a separate task not related to the database, the contractor obtained detailed species profiles for a number of selected hydrocarbon solvents and solvent mixtures. 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 components. The analytical methods identified and quantified VOC's present in common hydrocarbon solvents and solvent mixtures used in consumer products. These data will be used to support ARB's ongoing research involving reactivity of solvent mixtures.
