PHYSICAL PROPERTIES
o
Boiling point, C: 65 to 408 Color, Gardner scale: 1-6 Color, Pt-Co scale: 25-400
Color: clear, colorless, pale yellow, yellow, greenish to redidish, brown, black
Solubility (diluents): alcohols, water, ethers, hydrocarbons, toluene, acetone, chlorinated sol-
vents, aliphatic solvents and low molecular weight cyclic polydimethylsiloxane; miscible with
organic solvents, such as ethers and hydrocarbons. Mixing with ketones results in imine formation,
while mixing with alcohols other than methanol leads to an autocatalytic exchange of alkoxy
groups until the system reaches thermodynamic equilibrium
Evaporation rate (butyl acetate=1): <1
