Weigh 5g of ethoxylated crude oil sample (accurate to 0.001g) in a 250ml Kjeldahl flask or a 3-corner flask, add 1ml of nitric acid to soak the sample, place it for a while, slowly heat it, wait for the effect to ease, cool it, add 5ml of sulfuric acid (2.3.1.1.2) along the wall of the flask, and slowly heat it again until the solution in the flask begins to turn brown. Continuously add nitric acid until the organic matter is completely decomposed, add fire, and a large amount of white sulfur dioxide smoke is generated. The final solution should be colorless or yellowish. After cooling, transfer the solution to a 50ml volumetric flask, wash the 3-corner flask with a little water 2~3 times, add the washing solution to the volume, add water to the scale, mix well, and collect 10ml of this solution equivalent to 1g of sample.
