摘要
采用GC/MS对棉秆与杂木2种木醋成分进行了检测,结果表明,2种木醋主要成分分别是酸类、酮类、酚类、醇类等有机物质,棉秆木醋有30种成分,杂木则有41种;棉秆木醋的酚类物质远远高于杂木木醋的,但其他有机物质分别少于杂木木醋.理化指标比较显示,杂木木醋颜色相对棉秆木醋较稳定,棉秆木醋焦油含量低于杂木木醋2.7倍.
Cotton stalk vinegar and miscellaneous wood vinegar had been analyzed comparatively. Their wood vinegar composition was detected by GC/MS mainly. The major components of the two wood vinegar were acids, ketenes, phenols, alcohols, and other organic materials. There were 30 and 41 kinds of components respectively in cotton stalk vinegar and miscellaneous wood vinegar, but other organic materials were less than in miscellaneous wood vinegar. Physical and chemical indicators showed that the color of cotton stalk vinegar was less stable than that of miscellaneous wood vinegar. The tar content of cotton stalk vinegar was 2. 7 times less than that of miscellaneous wood vinegar.
