Two compounds have been isolated from hard coral Porites Compressa Dana,their structures were determined by IR,MS, HNMR, 13CNMR analysis.The two compounds are: batyl alcohol,(2) N-[l--2-hydroxyl--3,7-heptadecadienal]- h exadecanamide.

从采自西沙群岛的扁缩滨珊瑚中的石油醚部分分离出两个化合物，经IR、MS、~1HNMR、~(13)CNMR等波谱方法鉴定，其结构分别为(1)鲨肝醇，(2)N-1-羟基甲基-2-羟基--3，7-十七碳二烯基十六酸酰胺。

The results show: in a specific concentration range, the solubility in neutral solution of SOL, as well as the surfactivity, the ability to reduce ITF and the wettability on the condition of non- alkali are better than the lignosulfonate in market.While using as sacrifice agent, the modified lignosulfonate can reduce 60% of the mahogany sulfonate and 50% of the α-alkene sulphonate which both are adsorbed on the oil sand surface.

结果表明在一定浓度范围内，SOL在中性溶液条件下的溶解性、在无碱条件下的表面活性、降界面张力能力、对岩石的润湿性效果优于市场木质素磺酸盐产品；作为牺牲剂使用时，改性磺化木质素能减少石油磺酸盐在油砂表面吸附的60%，减少α-烯烃磺酸盐在油砂表面上吸附的50%。
