Part A contains the inorganic, organometallic, and organononmetallic liquids, and the binary liquid mixtures (about 900 pure substances and their mixtures). Part B contains data of more than 7600 organic liquids.

- 上游原料:10-十一烯酸 --> 蓖麻油酸 --> 蓖麻油酸乙酯(即12-羟基-9-十八碳烯酸乙酯)
- 方法二:由十一烯酸与乙醇酯化而得。原料十一烯酸和乙醇在硫酸催化下直接酯化得粗十一烯酸乙酯,再经中和、水洗及减压分馏得成品。另一种生产方法是由甘油三蓖麻醇酸酯与乙醇进行酯交换,得到蓖麻油酸乙酯,然后在550-600℃下裂解。将裂解液减压分馏,收集150-220℃(2.67-8.0kPa)馏分,即为十一烯酸乙酯。
