摘要：
In this work, a series of hydroxymethyl tetramide (HMTEA) was synthesized from vegetable oil, triacetylenetetramine and hexamethylenetetramine, which was evaluated as viscosity reducer and pour point depressor for crude oil. The results showed that HMTE has a good viscosity reduction effect on the crude oil from Yanchang Oilfield, with the highest viscosity reduction rate of 93%. The highest pour point reduction depression was achieved as 6.5 degrees C. Differential scanning calorimetry and paraffin crystal morphology characterization were conducted on the crude oil to elucidate the mechanism of viscosity reduction and pour point depression.
