Embodiment
[0023] In 1000 grams of primary hydrogenated oil, add 2 grams of activator citric acid, stir and dissolve, then add binary solid stable chlorine dioxide that accounts for 0.25% of the weight of primary hydrogenated oil and is made of 4 times the weight of water Solution, stirred for 1 hour, drained the reaction solution after settling for 25 minutes to obtain a precipitate; neutralized the precipitate with alkaline neutralizing agent sodium hydroxide to neutrality; then added 300 grams of water for washing until the oil product was Neutral, after draining clean water, it can be obtained. The above steps are all carried out under normal temperature and pressure. It is distilled to obtain the aromatic solvent oil that meets the market demand.
