Abstract: The purpose of solvent dewaxing is to prevent corrosion, protect catalyst in subsequent processes, and improve finished products by removing unsaturated, aromatic hydrocarbons from lubricant and grease stocks. The solvent dewaxing process separates aromatics, naphthenes, and impurities from the product stream by dissolving or precipitation. When powerful ultrasound of higher frequency is applied to a system, it is possible to produce physico chemical changes in organic solvent mixture. The ultrasonic velocity and density measurement has been undertaken in presence of high intense ultrasonic beam at 3MHz in binary mixture of MIBK with toluene. The solvent dewaxing process is discussed in terms of molecular interaction by calculating acoustic parameters and their deviated values.The variation of different acoustic parameter with temperature and concentration shows the effect of ultrasonic wave in dewaxing process of crude oil
