【摘要】 报道了一种可用于棉花、大豆等多种农作物的新型高效植物生长调节剂2-(3,4-二氯苯氧基)乙基二乙胺(增产胺)的合成新工艺。该工艺以3,4-二氯苯酚和2-氯乙醇为原料,先通过酚的烷基化反应,然后磺化,最后进行胺化,三步反应得到成品增产胺。试验结果表明,该方法具有污染小、产率高、周期短、条件温和等优点,是一条适于工业化生产的合成新方法。化合物的结构已为元素分析1、H核磁共振谱等表征所证实。更多还原

【Abstract】 A new method for synthesis of plant growth regulator 2-(3,4-Dichlorophenoxy) ethyldiaklamine for various crops such as cotton and soybean was developed.2-(3,4-Dichlorophenoxy) ethyldiaklamine was successfully synthesized through O-alkylation of the materials 3,4-dichloriphenoxy and chloroethanol,then sulfonation and finally amination.The improved method was characterized by low cost,high yield and short circle,which was suitable for large-scale production.更多还原
