为了研制航空燃料油的稳定剂,以脂肪酸1为原料,在三氯化磷存在下与溴反应,制得2-溴代脂肪酸2.化合物2在60～90℃石油醚中与氨基乙醇钠进行Williamson反应,盐酸中和,制得2-(2-氨基乙氧基)脂肪酸盐酸盐(3).以95％的乙醇为溶剂,在氢氧化钾存在下,化合物3与环氧氯丙烷反应后,冰醋酸酸化,合成了2-[2-(2,3-环氧-1-丙氨基)乙氧基]脂肪酸(4).化合物3和4均属新化合物.
In order to develop a stabilizer for aviation fuel oil, fatty acid 1 is used as a raw material and reacted with bromine in the presence of phosphorus trichloride to obtain 2-brominated fatty acid 2. Compound 2 is reacted with sodium aminoethanol in petroleum ether at 60-90 ° C Williamson reaction and hydrochloric acid to obtain 2- (2-aminoethoxy) fatty acid hydrochloride (3). Compound 3 was reacted with epichlorohydrin in the presence of potassium hydroxide as a solvent in 95% ethanol After the reaction, acetic acid was acidified to synthesize 2- (2- (2,3-epoxy-1-propylamino) ethoxy] fatty acid (4) Compounds 3 and 4 were new compounds.
