I.Brief Introduction:

• Test for Oil Content of Petroleum Wax"

• It is suitable to determine the oil content of petroleum wax, the congealing point of which is higher than 30 °C and the oil content of which is not more than 15%.

• The method is expressed as follows: Solve sample in the methyl ethyl ketone and cool it to -32 °C to separate wax out. 

• Filter it and evaporate methyl ethyl ketone in the filtering liquid

• Weigh the residue and calculate the oil content in the wax

Note: For some wax having oil content higher than 5%, if the oil could not be completed dissolved in the methyl ethyl ketone, please don't use this instrument.
