Polychlorinated 2-phenoxyphenols were studied by negative ion mass spectrometry. Common to almost all of the methane enhanced negative ion mass spectra were (M-1)-, (M-36-)-., (M-37)-, (M-72)-., and chorinated quinoxide ions. The (M-36)-. ion does not apparently form in a mechanism analogous to the thermal or photochemical ring closure of these compounds to form the chlorinated dioxins. The chlorinated quinoxide ion reflects the number of chlorines on the ring with hydroxy substituent. Collision-induced dissociation mass-analyzed ion kinetic energy spectra (CID-MIKES) from different isomers were qualitatively different in both the normal and charge reversed mode of operation. Comparison of these spectra with those from other classes of polychlorinated aromatic hydrocarbons such as the dioxins or the furans may reveal a common negative ion gas phase chemistry.
采用负离子质谱法对多氯代2-苯氧基苯酚进行了研究。几乎所有甲烷增强负离子质谱中都常见的离子有(M - 1)-、(M - 36)-、(M - 37)-、(M - 72)-以及氯化醌氧化物离子。(M - 36)-离子显然不是通过类似于这些化合物热环化或光化学环化形成氯化二噁英的机制形成的。氯化醌氧化物离子反映了带有羟基取代基的环上氯的数量。在正常和电荷反转操作模式下，不同异构体的碰撞诱导解离质量分析离子动能谱（CID - MIKES）在定性上有所不同。将这些谱图与二噁英或呋喃等其他多氯代芳烃类别的谱图进行比较，可能会揭示一种常见的负离子气相化学性质。
