摘　　要：以二乙烯三胺和可再生生物质——妥尔油酸为原料,考察了3,4,5-三氟苯硼酸、磷酸和氢氧化钾等催化剂对妥尔油基胺乙基咪唑啉(TON100)转化率的影响,用傅里叶变换红外光谱和ES-MS对TON100结构进行了验证。用静态失重法考察了TON100在盐酸和硫酸溶液中对A3钢片的缓蚀性能测试。结果表明,3,4,5-三氟苯硼酸作催化剂,添加量为总量的0.3wt%,反应温度为230℃时,妥尔油酸转化率为99.4%;在4%盐酸溶液中,实验温度为90℃,TON100添加量为50 mg/L时,缓蚀率最高为95.1%;在4%的硫酸体系中,30℃时,TON100添加量为100 mg/L时,缓蚀率为85.1%。Tall oil acid is a renewable biomass material.In this work,the effects of different types of catalysts such as 3,4,5-trifluorophenylboronic acid,phosphoric acid,and potassium hydroxide on the conversion rate to tall oil aminoxyethyl imidazoline(TON100)were investigated,in which diethylenetriamine and tall oil acid were used as raw materials.The structure of TON100 was characterized by FT-IR and ES-MS.Its corrosion inhibition performance to A3 steel sheets in hydrochloric acid solution and sulfuric acid solution was investigated by static weight loss method.The results showed that when the reaction temperature was 230℃,3,4,5-trifluorophenylboronic acid was used as a catalyst and its amount was 0.3 wt%of the total amount,the conversion rate of tall oil acid was 99.4%.In a 4 wt%hydrochloric acid solution,the best dosage of TON100 for corrosion inhibition was 25 mg/L at 30℃and 60℃.In contrast,at the experimental temperature of 90℃,the best dosage of TON100 was 50 mg/L and the highest corrosion inhibition rate was obtained as 95.1%;at 30℃,in a 4 wt%sulfuric acid solution,when the amount of TON100 added was 100 mg/L,the corrosion inhibition rate was 85.1%.Therefore,TON100 had good corrosion inhibition effects against both hydrochloric acid and sulfuric acid.
