Abstract

The invention discloses a gasoline copper plate corrosion inhibitor, which belongs to the technical field of gasoline corrosion inhibition and is prepared from the following raw materials in parts byweight through compounding: 3 to 6 parts of potassium hydroxide, 10 to 20 parts of sulfonated phthalocyanine cobalt, 2 to 3 parts of acetylacetone cobalt, 5 to 7 parts of sodium benzoate, and 2 to 6 parts of sodium acetate. The inhibitor provided by the invention is good in susceptibility, wide in application range, and free of causing an unqualified phenomenon due to a raw oil property change; issufficient in reaction, favorable in dispersing effect, and free of generating sediments or causing adverse effects on production detection and use; is suitable for industrial production, capable ofmeeting the industrial use requirement since the added sodium benzoate is an excellent corrosion remover, and capable of playing a role in preventing corrosion in a relative harsh environment; is capable of playing a role in dispersing during a product storage process and preventing a complexing reactant in the product from settling and precipitating to cause a large number of precipitates in a storage tank, and capable of being stored for a long time.

Description

technical field [0001] The invention relates to a gasoline additive, in particular to a gasoline copper sheet corrosion inhibitor and a preparation method thereof. The invention belongs to the technical field of gasoline corrosion inhibition. Background technique [0002] Passing the copper corrosion test is one of the important standards for testing the quality of gasoline. At present, gasoline produced by catalytic cracking of heavy oil generally has the problem of unqualified copper sheet corrosion. As a result, oil refiners are often forced to re-refine or re-blend such gasoline before it can be sold as qualified refined oil, which has a great impact on economic benefits of the refinery. It can be seen that solving gasoline copper sheet corrosion has become an imminent technical problem for gasoline manufacturers. There are many kinds of gasoline copper corrosion inhibitors, which are mainly divided into amines and phenols. [0003] The reasons for copper sheet corro...
