The methyl ethers of a number of hydroxylated (poly)chlorodibenzo-p-dioxins, chlorodibenzofurans, chlorodiphenyl ethers and chloronaphthalenes, representing all different hydroxy substitutions, were synthesized and their mass spectra investigated. With the exception of the methoxy derivatives of the chlorodibenzofurans, it appeared that the mass fragmentation patterns of the structural isomers of each
合成了代表所有不同羟基取代基的许多羟基化(聚)氯二苯并-对-二恶英,氯二苯并呋喃,氯二苯醚和氯萘的甲基醚,并对其质谱进行了研究。除了氯二苯并呋喃的甲氧基衍生物外,似乎每一类化合物的结构异构体的质量碎裂模式都是非常特异性的,并且可以明确分配分子中甲氧基的位置。可以根据导致稳定的电荷离域(oxonium)离子的合理机理来解释不同的碎裂模式。由于其诊断价值,该方法可用于阐明氯二苯并-对-二恶英的纯异构体的羟基化代谢物的结构,
