The work is related to the field of preparation of emulsifiers for the use in asphalt emulsions, and formulating of solution type cooling - lubricating fluids. Thus, castor oil was reacted with gaseous sullur trioxide at 2:5°c using carbon tetrachloride as a solvent. Emulsification properties of the sulfurized castor oil were studied in relation to the content of combined SO3. The highest emulsification tendency was attained at approximate 8 percentages by weight of SO3 content corresponding to the sulfation of one hydroxide group in castor oil.
