Aniline Point and Mixed Aniline Point of Petroleum
Products and Hydrocarbon Solvents
Test Method
Aniline point is used to characterize pure hydrocarbons and to indicate the
aromatic content of hydrocarbon mixtures. Equal volumes of aniline and
sample or sample plus n-heptane are stirred together while being heated
at a controlled rate. After the two phases become miscible, the mixture is
cooled at a controlled rate and the temperature at which the two phases
separate is the aniline point or mixed aniline point of the sample.
Automatic Aniline Point Apparatus
. Conforms to ASTM D611 and related specifications
. For samples ranging from clear to very dark
. Temperature range 0°C to 150°C (32°F to 302°F)
. Digital temperature display
Performs aniline point and mixed aniline point determinations automatically
by means of a modified thin film technique (ASTM D611 Method E). The
sample-aniline mixture is directly heated by a platinum immersion heater
and the aniline point is detected photoelectrically. Temperature is displayed
on a large LED indicator. Built-in pressure regulator and solenoid valve
permit the use of cooling air for quicker cooling cycles or to determine
sub-ambient aniline point temperatures. Aniline points as low as 0°C (32°F)
can be determined with the use of refrigerated cooling air. Equipped with
variable controls for heater, light source and stirrer speed. Cabinet exterior
surfaces have a chemical resistant polyurethane enamel finish.
