Description
Petroleum distillates are colorless liquid petrochemical
mixtures with kerosene-like odor and a boiling range of
90–240 °C containing hydrocarbons ranging between C7
and C12 divided into three major components. The group
with highest proportion (30–50%) is usually linear and
branched alkanes. The second group of relevant components
is cycloalkanes, which can be found in petroleum distillates
between 30 and 40%. Finally aromatic hydrocarbons can
also be found in significant proportions up to 25% in these
distillates. Nevertheless, it is important to keep in mind that
petroleum distillates may change over the years, mainly due
to different origins of crude oils used for production and
changes undergone in the refinery processes, which can
conduce to variations in the exact composition of the same
product even among different manufacturers. It is also remarkable that the name ‘petroleum distillates’ might
include other preparations coming from different distillations
of crude petroleum; indeed, European regulation for
classification of labeling of chemicals considers petroleum
distillates as a total of 12 different products, five with CAS
number as described above plus another seven preparations
corresponding to heavier distillation fractions (higher
than C15).The petroleum distillates can be divided into three different
categories according to the manufacturing procedure, that might
be by catalytic hydrodesulfurization (type 1), by solvent extraction
(type 2), or by treating a petroleum fraction with hydrogen
in the presence of a catalyst (type 3) . The proportion or
aromatics is lower than 25, 5, and 1% for types 1, 2, and 3,
respectively. A special preparation of petroleum distillate type 1
is manufactured in the United States under the name of Stoddard
solvent. A fourth type (type 4) might be considered as
a crude mixture not treated beyond the process of distillation.
Petroleum distillates types 1, 2, and 3 are further divided
into three technical grades, which are defined by flash point:
low flash petroleum distillates (ranging between 21 and 30 C),
regular flash petroleum distillates (ranging between 31 and
54 C), and high flash petroleum distillates (with flash point
higher than 55 °C).Petroleum solvents are included by International Agency for
Research on Cancer within Group 3 (not classifiable as to its
carcinogenicity to humans). However, the current European
regulations consider distillates as belonging to carcinogen
category 1B (presumed to have carcinogenic potential for
humans) and require that these distillates be labeled with the
hazard statement H350 (may cause cancer). In addition, they
are also classified for aspiration toxicity and mutagenicity.

Uses
Coating agent; float; food additive; frothflotation cleaning; insecticide formulations component. Petroleum distillates are used as extraction, cleaning, and
degreasing solvents. The industrial uses of petroleum distillates
include solvent in aerosols, paints, wood preservatives, waxes,
asphalt products, photocopier toners, printing inks, adhesives,
dry cleaners, lacquers, and varnishes. White spirit is generally used:As a solvent for the extraction of oil-bituminous rock organic components from mineral.As a component in the mixture of organic liquids to clean the coal samples by float/sink gravity separations.White spirit with ~17% aromatics basis can be used as a solvent in the synthesis of alkyd resin from camelina oil.
