以不同结构的伯胺和环氧氯丙烷为原料合成聚胺,采用高氯酸非水滴定法测定产品的总胺值和叔胺值,使用蒸气压渗透法(VPO)测定产品的相对分子质量,并用红外光谱对其产品结构进行表征,最后将聚胺与癸烯聚砜进行复配,添加到0号商品柴油中,对其抗静电性能进行评价.结果表明:不同结构的聚胺与癸烯聚砜复配都能明显提高0号商品柴油的电导率,其中以链状脂肪伯胺合成的聚胺的抗静电效果远比环己胺聚胺和苯胺聚胺的效果好；当正丁胺聚胺与癸烯聚砜加剂量均为2 mg/L时,0号柴油的初始电导率从3 pS/m增加到487pS/m;储存9天时,柴油电导率超过2 000 pS/m,且能稳定储存25天以上；加剂量对柴油电导率影响较大,十二胺聚胺与癸烯聚砜复配,加剂量均为0.5 mg/L即能满足使用要求,而正丁胺聚胺和癸烯聚砜加剂量均为0.8 mg/L以上才能满足要求.%Polyamines were synthesized with different primary amines and epichlorohydrin.The total amine value and the tertiary amine value of the products were determined by the methods of perchloric acid nonaqueous titration.In addition,the vapour pressure osmometry (VPO) was used to determine the molecular weight of the products,and the structures of the products were characterized by infrared spectroscopy.Then,polyamines together with poly (1-decene sulfone) were added to commercial diesel fuel to evaluate its antistatic properties.The results show that the polyamines with different structures can improve the conductivity of the commercial diesel significantly,and the performance of the polyamine synthesized by chain fatty amines is perfect.When the dosage of the n-butylamine polyamine and the poly (1-decene sulfone) are both 2 mg/L,the conductivity of the 0# diesel can increase from 3 pS/m to 487 pS/m.After 9 days stored,the conductivity of the 0# diesel increased to more than 2 000 pS/m,and did not decrease even stored in 25 days.The dosage of anti-static additive has Great influence on the conductivity of diesel.When the dosage of the dodecylamine polyamine and the poly (1-decene sulfone) were both 0.5 mg/L,the conductivity of the 0# diesel can satisfy the use requirement,and to meet the requirements,the dosage of the n-butylamine polyamine and the poly (1-decene sulfone) were both 0.8 mg/L.
