Stoddard solvent (8052-41-3)
Weathered Petrochemical Standards
These solutions are prepared from a single-source (one-refin-
ery) product. The weathered materials indicate the percent
weight loss from the original material. Samples of regular- and
premium-grade unleaded gasoline were collected, then blended
in equal volumes.
There are four general types of mineral spirits, classified accord-
ing to boiling point range (BPR):
• Type I (Stoddard solvent) BPR 149–182 °C
• Type II (high flash point) BPR 177–196 °C
• Type III (odorless)
BPR 149–196 °C
• Type IV (low dry point) BPR 149–174 °C
Stoddard Solvent Standard
Stoddard solvent is also known as Type I mineral spirits,
Texsolve S, or Varsol® 1 mineral spirits. We offer this reference
material for those who need to calibrate Stoddard solvent sep-
arately. This standard is dissolved in methanol for analysis by
either direct injection or purge-and-trap.
