CAS: 134-11-2
分子式: C9H10O3
分子量: 166.17

性质描述: 无色油状液体。熔点20.7℃，沸点174-176℃（2.0kPa），相对密度1.105，折光率1.5400。溶于热水，微溶于醇及冷水。
生产方法: 由水杨酸甲酯（[119-36-8]）与碘乙烷合成邻氧基苯甲酸甲酯，再经水解、酸化而得。将金属钠、水杨酸甲酯、碘乙烷依次加入无水甲醇中，加热回流10h。回收甲醇及碘乙烷后倒入冷水中，分取油状物。用水及5%氢氧化钠溶液洗至pH=7，用乙醚提取，用无水碳酸钠干燥后回流乙醚，然后减压蒸馏得到邻乙氧基苯甲酸甲酯。将其加入5%氢氧化钠溶液中回流2-3h，放冷，用乙醚提取未反应的酯。提取后的水溶液用盐酸酸化，用水洗涤油层。再加5%氢氧化钠溶解，过滤后再用盐酸酸化，到出油层，冷冻结晶出粗品。酸化后的水层可用乙醚提取，也能得到一部分粗品。粗品经减压蒸馏即得成品邻乙氧基苯甲酸。
用途: 用于医药中间体、有机合成。
