White spirit is a transparent, clear, and
petroleum-derived clear liquid with a detectable characteristic odor. It is
composed of complex hydrocarbon mixtures produced by hydro-treating petroleum
cut. It is first developed in 1924 by Atlanta dry cleaner W. J. Stoddard and
Lloyd E. Jackson who worked in the Mellon Institute of Industrial Research. Now
there are three common types and grades of white spirits depending on its
applications and the crude oil used for the first starting component.
types of white spirit are obtained by the distillation from naphtha and
kerosene components of crude petroleum. In terms of white spirit type 1, the
most common and traditional white spirit, 25 percent of its aromatics are
obtained from the straight-run kerosene and straight-run naphtha by the
fractional distillation process. Additionally, either after or before the
distillation, a hydrodesulfurization step needs to be taken.
petroleum distillate, white spiritâ€™s most common applications are mild solvent
and paint thinner. It is also used as an organic solvent due to its solvent
properties. White spirit is used as an extraction solvent, as a degreasing
solvent, and as a cleaning solvent.
used to clean and degrease machine tools and parts in industry. It can also be
used to cut oil as a reaming lubricant and thread cutting. White spirits are an
inexpensive petroleum-based replacement for the vegetable-based turpentine. It
is commonly used as a paint thinner for cleaning brushes.
