White Spirit 1 and 2

Naphtha is generally subject to hydrogenation refining, with the aim of improving color, enhancing stability, reducing corrosive substances and lowering toxicity, etc. Hydrofining technology is an important processing unit process in the hydrodesulfurization refining technology of naphtha. Modern oil refineries and petrochemical integrated enterprises at home and abroad basically adopt the hydrorefining process as the main technical method to improve the quality of oil products. Naphtha hydrodesulfurization can be applied in edible oil, printing ink, leather, pesticides, insecticides, cosmetics, fragrances, chemical polymerization, medicine and electronic cleaning, etc. Synthesis: Epiclo Chemical BooknAM-040-P 37.4g (20mmol) and 4-phenylphenol 2.72g (16mmol) were dissolved in 100ml of DMA, and then 0.52ml of 65% ethyl acetate triphenylphosphonium ethanol solution was added under a nitrogen atmosphere. Let it react at 120°C for 6 hours. After cooling, a large amount of water was added dropwise, and the resulting sediment was further washed with a large amount of water. Filter and precipitate the product, and then dry it under reduced pressure. The hydrodesulfurization of naphtha was obtained. The product yield is 100%. Perform 1H-NMR measurement to confirm its structure.
