摘要
采用红外、色质联用等分析手段对孤岛原油中羧酸的分布、结构及组成进行了研究。结果表明，孤岛原油中石油羧酸平均相对分子质量在490左右，脂肪酸中C14-16成分占50％以上；原油中环烷酸的碳数在9～30之间，相对分子质量范围为156～450。
The structure and composition of petroleum acids isolated from Gudao crude oil were investigated by means of IR and GC/MS. Results indicate that the average molecular weight of the petroleum acids is about 490. The C14~C16 components cover nearly 50% in total petroleum acids. The number of carbon atoms in naphthenic acids from crude oil are in the range of 9~14 with molecular weights of 156~450.
