【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。更多还原

【Abstract】 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.更多还原
