由于三十烷醇在农业生产中的增产作用,国内外越来越广泛地受到重视,三十烷醇分析方法的研究就显得至为重要。据所见资料表明,高碳烷醇含量多采用气相色谱分析,但由于三十烷醇沸点(244℃/0.5毫米汞柱)远高于国产仪器所能达到的最高气化温度(250°～350℃)。为解决此矛盾,有的文献提出将三十烷醇转化成烷烃或相应的酯,以降低沸点,再用气相色谱测定,间接测出三十烷醇含量。但此法要求转化必须达到实际完全的程度,且分析周期长达数十小时。上海粮食科研所用日
Due to the increasing production of triacontanol in agricultural production, more and more attention has been paid at home and abroad. The study of triacontanol analysis method is very important. According to the information we have seen, the higher the content of higher alkanols by gas chromatography, but the boiling point of triacontanol (244 ℃ / 0.5 mmHg) is much higher than the maximum gasification temperature (250 ° ~ 350 ° C). In order to solve this contradiction, some literatures propose to convert triacontanol into alkanes or corresponding esters to lower the boiling point, and then indirectly measure the content of triacontanol by gas chromatography. However, this law requires that the conversion must reach a practically complete level, with analysis periods of up to several tens of hours. Shanghai Food Research Day
