摘要：
A pour point depressant additive has been developed to reduce the pour point of paraffinic oils. The depressant contains a (non-ionic) surfactant, a depressant component and a solvent. The depressor properties of the developed compositions have been studied. It has been established that while adding the compositions to the oil mixture, at a concentration of 0.02% wt. the pour point decreases from +31 degrees C to -3 divided by +7 degrees C, and at a concentration of 0.04% wt. up to -5 divided by + 4 *C. Under the effect of the developed compositions the oil viscosity at + 35 degrees C decreases from 46.3 mPa.s to 22.1 divided by 27.7 mPa.s, and at + 40 CC - from 38.2 mPa.s to 16.6 divided by 21.6 mPa.s. Viscosity reduction performance at the indicated temperatures are 40.2 divided by 51.6% and 43.5 divided by 56.5%, respectively. Compositions 8, 14 and 17 exhibit higher depressor properties.
