27.6 What are white spirits?

White spirits are petroleum fractions that boil between 150-220C. They can
have aromatics contents between 0-100%, and Shell lists eight grades with
aromatics contents below 50%, and six grades with aromatics contents above
50%. The two common "white spirits" are defined by British Standard 245,
which states Type A should have aromatics content of less that 25% v/v and
Type B should have an aromatics content of 25-50% v/v. The most common
" white spirit" is type A, and it typically has an aromatics content of
20%, boils between 150-200C, and has an aniline point of 58C, and is
sometimes known as Low Aromatic White Spirits. The next most common is
Mineral Turpentine (aka High Aromatic White Spirits ), which typically has
an aromatics content of 50%, boils between 150-200C and has an aniline
point of 25C. For safety reasons, most White Spirits have Flash Points
above ambient, and usually above 35C. Note that "white gas" is not white
spirits, but is a volatile gasoline fraction that has a flash point below
0C, which is also known by several other names. Do not confuse the two
when purchasing fuel for camping stoves and lamps, ensure you purchase the
correct fuel.
