What does the acid value on our paraffin oil hydrogenation analysis sheet represent?
High acid value indicates a high amount of acidic substances in the oil, resulting in strong corrosivity； Low acid value, with fewer acidic substances in the oil, resulting in low corrosivity
The number of milligrams of potassium hydroxide required to neutralize the acidic substances in 1 gram of test oil is called the acid value. The acid value is used to help select materials; generally, before reactions at temperatures above 240 degrees Celsius, corrosion caused by naphthenic acid must be taken into consideration, while such corrosion is not an issue after hydrogenation reactions
