SOLVENT CHEMISTRY OVERVIEW
  • What is a solvent?
  • In its simplest definition, it is a substance,
    usually a liquid, that dissolves or can dissolve
    another substance. Most of the time, a solvent
    is an organic liquid, i.e. based on
    carbon-containing chemistry.

SOLVENT CHEMISTRY OVERVIEW
  • Types of solvents
  • Non-polar/Polar
  • Hydrocarbon
  • Aliphatic naphtha, mineral spirits, heptane,
    hexane, propane, etc.
  • Cycloparaffins cyclohexane, etc.
  • Aromatic toluene, xylene, aromatic 100, etc.

4
SOLVENT CHEMISTRY OVERVIEW
  • Oxygenated
  • Ketones acetone, MEK, MIBK, MBK, MPK, etc.
  • Esters methyl acetate, ethyl acetate, DBE,
    etc.
  • Ethers dimethyl ether, ethyl ether, etc.
  • Glycol ethers EB, PM, PnP, DB, etc.
  • Glycol ether acetates PM acetate, DB acetate,
    etc.
  • Glycols ethylene glycol, propylene glycol,
    hexylene glycol
  • Alcohols methanol, ethanol, isopropanol, etc.
  • Others n-methyl pyrrolidone, AMP, THF

SOLVENT CHEMISTRY OVERVIEW
  • Chlorinated
  • methylene chloride, trichloroethylene,
    perchloroethylene
  • Natural solvents
  • citrus terpenes, pine oil, soy methyl ester
  • Other
  • VMS, HFEs, HCFCs, HFCs, DMF, etc.
  • Water
  • The most common solvent

SOLVENT CHEMISTRY OVERVIEW
  • Mass-based/reactivity-based regulatory
    considerations
  • EPA has suggested that relative
    reactivity-based regulations may help provide the
    flexibility necessary to achieve further
    emissions reductions from some source categories
    to address persistent ozone non-attainment
    problems..

    California State Implementation Plan and Revision
    to the Definition of Volatile Organic Compounds
    (VOC) - Removal of VOC Exemptions for
    California's Aerosol Coating Products
    Reactivity-based Regulation Proposed Rule"
