Solvent S-316

Characteristics
Solvent S-316 has the characteristics shown below, and satisfies the conditions required of a
solvent for oil content extraction.

Although there is absorption near the 3000 cm
-1
absorption wavelength of the
hydrocarbon group, this absorption can be clearly distinguished from that of oil.

Available for measurement in wide range of temperature due to the boiling point of 134°C
and the melting point of
− 143°C.

Chemically stable in acid, alkali, oil and water.

Little solubility in water.

Involatile, with a low vapor pressure.

Non-flammable, no danger of explosion

Low toxicity for the human body, very safe.

Reclamation of solvent
To reduce running costs and help protect the global environment, it is recommended that S-
316 is reclaimed. To reclaim solvent, use the optional SR-305 solvent reclamation unit.
Tip
Solvent reclamation unit (SR-305) uses activated carbon and alumina layers to efficiently reclaim the
solvent.
For the solvent reclamation procedure, refer to the manual for the SR-305 solvent reclamation
unit.
This section describes handling methods and cautionary points for efficient reclamation of
solvent.

Absorbents
The following 2 types of absorbents are used in the solvent reclamation unit.

Activated carbon:
Removes oils, fats, and other substances that do not dissolve in water.

Activated alumina:
Removes water content and substances that easily dissolve in water.
Note
Store absorbents in a dry location. If an absorbent becomes damp, its performance will drop
noticeably.
