摘要: 采用本体聚合法,以TiCl4为主催化剂、Al(i-Bu)3为助催化剂合成α-己烯/α-十二烯减阻剂。用IR,1HNMR,TG等手段对聚合物结构进行表征。考察了主催化剂用量、助催化剂用量对减阻剂特性黏度的影响,采用室内环道评价装置对减阻率进行测试。结果表明,在主催化剂用量为0.09 g、助催化剂用量为0.12 mL、α-十二烯与α-己烯体积比2:1(α-十二烯与α-己烯总体积为40 mL)、反应时间为48 h、反应温度-5 ℃的条件下,聚合物特性黏度为11.21dL/g;当减阻剂在柴油中质量分数为10 g/g时,减阻率达到50.81%。

Abstract: A drag reducing agent (DRA), α-hexylene/α-dodecene, was synthesized by bulk polymerization using TiCl4/Al(i-Bu)3 as catalyst. The obtained polymer was characterized by means of IR, 1HNMR and TG. The effect of main catalyst and co-catalyst dosages on the intrinsic viscosity of the synthesized DRA was investigated and its drag reducing efficiency was tested with a loop evaluation device. Results showed that under the optimum conditions of a main catalyst dosage of 0.09 g, a co-catalyst dosage of 0.12 ml, α-dodecene/α-hexylene volume ratio of 2 (a total volume of 40 mL), a reaction temperature of -5 ℃ and a reaction time of 48 h, the intrinsic viscosity of the synthesized DRA was 11.21 dL/g; by adding said DRA to diesel fuel at a dosage of 10 g/g, its drag reducing rate reached 50.81%.
