White Spirit

      White spirit( Solvent 402 ) also known as mineral spirits, mineral turpentine (AU/NZ), turpentine substitute, petroleum spirits, solvent naphtha (petroleum), varsol, MTO,  and paint thinner, is derived from the naphtha layer of the distillation column.

      Solvent 402 has two grades, grade A and grade B.

      White spirit has different types and grades such as solvent 404, solvent 406, and solvent 410, grade C and so on.

       This classification and grading are based on the oil extraction, the area, the production reactor and so on.

      Infinity Galaxy predominantly supplies white spirit or solvent 402 in two grades of A and B.

      Grade A is highly applied in painting buildings and oil thinner in the India market.

      Grade B has a vast application in gasoline, fuel, and hydrocarbon in the India market.

      It also has other usages as in producing MC bitumen, paints, lacquers, aerosols, varnishes, households, etc.

       White spirit can also be mixed with recycling motor oil to produce hydrocarbons specified for the factories. Reference to density is important to discriminate white spirit grades A and B.

       

      • Grade A

      As shown in the chart, LAWS (Low Aromatic White Spirit) grade A has a density as written below.

      0.775 ≤Density of Grade A≤ 0.785 (measured by ASTM D 1298)

      The IBP (Initial Boiling Point) of this grade is between 142 and 158c. (Measured by ASTM D 86)

      “90% evaporated “in the chart indicates the temperature at which 90% of the content evaporates, which has been measured by ASTM D 86.

      The drypoint is the point in which all the content evaporates.

      For grade A, the drypoint is less than 210c.

      Low aromatic white spirit grade-A has a water-white color and has less than 1% sulfur.

      As its maximum aromatic content is 20, it is not smelly and is appropriate for residences and public areas.

      • Grade B

      Low Aromatic White Spirit grade B has some differences with the abovementioned grade.

      Grade B is a water-white yellowish solvent which is suitable for fuels.

      As its aromatic content is more than grade A, it has a sharp odor.

      Its density is written below.

      0.785≤ Density of Grade B ≤0.798

      Its IBP is 156c and its FBP (Final Boiling Point) is 230.

      White spirits are also considered as a base element of Euro 4 gas.
