| titleOfInvention | Method for detecting petroleum acid in crude oil and chloroform bitumen |
| abstract | The invention relates to a method for detecting petroleum acid in crude oil and chloroform bitumen "A". The method comprises: dissolving polar components in crude oil and chloroform bitumen "A" into dichloromethane; transferring the obtained solution to a test tube; adding a boron trifluoride-methanol solution to the test tube; placing in an ultrasonic cleaning device to carry out oscillation, such that petroleum acid in the sample is subjected to an esterification reaction; after completing the esterification reaction, adding distilled water and dichloromethane to the test tube; placing in the ultrasonic cleaning device to carry out oscillation; taking the test tube, and carrying out standing or centrifugation separation; removing the upper layer aqueous phase; after completely volatilizing the solvent dichloromethane, adopting n-hexane as a solvent to transfer the sample into a Florisil (magnesium silicate) SPE small column, wherein residual hydrocarbons are washed away by using n-hexane, and petroleum acid methyl ester is washed away by using dichloromethane; and carrying out chromatography-mass spectrometry analysis on the two petroleum acid methyl ester sample, wherein rich normal saturated fatty acids (methyl ester) and other acid compounds are detected. The method has the following characteristics that: detection is rapid, and only requires a few hours, the reagents do not contain strong acid and strong alkali, and oil-gas field information can be accurately acquired with the detection method of the present invention. |
