  1. Hydrocarbon Solventsfor Chamber Testing Andrew Jaques, American Chemistry Council Hydrocarbon Solvents Panel California Air Resources Board Reactivity Research Advisory Committee June 13, 2002

  2. Hydrocarbon Solvents Panel Members: • CITGO Petroleum Corporation • ExxonMobil Chemical Company • Flint Hills Resources • Sasol, North America, Inc. • Shell Chemical LP • Sunoco, Inc.

  3. Hydrocarbon Terminology Aliphatics • n-paraffins • isoparaffins • cycloparaffins (naphthenes) Aromatics

  4. Hydrocarbon Solvents Overview • Products consists of carbon (C) and hydrogen (H) molecules in the C5-C20 range • Products composed of 2 major classes of compounds • Aliphatic hydrocarbons (normal, branched, cyclic) • Aromatic hydrocarbons (1 and 2 aromatic rings with alkyl side chains) • Products are multi-constituent hydrocarbons • Classes: n-alkanes, isoparaffins, cycloparaffins, aromatics • Combinations/blends of hydrocarbon classes • Physicochemical parameters are controlled • e.g., boiling range, isomeric structure/composition

  5. Hydrocarbon Solvent Test Candidates • See attached list of recommended hydrocarbon solvents. • General types of hydrocarbon solvents commonly used in coatings. • Loosely ranked. Panel believes all of these hydrocarbon solvent types are used in architectural coatings. • Recommend looking at results of 2001 ARB Arch. Coating Survey before finalizing priority list.
