Simple, selective, and identifiable analysis of aromatic monoamines with a surrogate on sulfuric acid impregnated filters by derivatization with an acid chloride reagent and HPLC with fluorescence detection

Inoue Naoko

摘要

Abstract > A simple and selective derivatization and detection method for o ‐toluidine, o ‐anisidine, and 2,4‐dimethylaniline was developed using a sulfuric acid impregnated filter, 4‐( N ‐chloroformylmethyl‐ N ‐methylamino)‐7‐nitro‐2,1,3‐benzoxadiazole, and a surrogate ( o ‐ethylaniline), which allowed simple, rapid, selective, and identifiable analysis by high‐performance liquid chromatography with fluorescence detection. These amines were successfully derivatized in a pH 5 buffer solution containing acetonitrile at 35°C for 10?min (linear in the range 0–400?ng/mL, n ?=?5, aromatic amines: r ?>?0.9980, aromatic amines with surrogate correction: r ?>?0.9997, aromatic amines in the presence of phenol and aliphatic amines with surrogate correction: r ?>?0.9996). The retention times of these derivatized aromatic amines were?<17?min using isocratic elution. No derivatives corresponding to phenol or the aliphatic amines (i.e., cyclohexylamine and hexylamine) were detected in the reaction solution. This method can therefore be considered applicable for the analysis of samples from occupational environments, as samples were successfully extracted, derivatized, and measured by high‐performance liquid chromatography following spiking of a sulfuric acid impregnated filter with aromatic amines, phenols, and aliphatic amines. Indeed, only the aromatic amines were quantitatively detected without pretreatment, with no other spiked compounds being detected. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > o </ i> -toluidine的简单和选择性衍生化和检测方法，使用硫酸浸渍过滤器，4-（ N-I> -Choroformylmethyl- N-I> N-Cl-I>开发了2,4-二甲基苯胺和2,4-二甲基苯胺 - 甲基氨基）-7-硝基-2,1,3-苯并肟唑，和替代（ o> - 乙基苯胺），其通过高性能液相色谱与荧光允许简单，快速，选择性和可识别的分析检测。这些胺在35℃下在含有乙腈的pH 5缓冲溶液中成功衍生化10≤min（在0-400〜400℃的线性， n / m>？5，芳族胺： r </ i>？> 0.9980，芳香胺，具有替代校正： r r℃，α.0.9997，芳族胺在苯酚和脂族胺存在下替代校正： r </ i>？>？0.9996）。这些衍生的芳族胺的保留时间使用等离心洗脱α<17·min。在反应溶液中检测到对应于苯酚或脂族胺（即环己基胺和己胺）的衍生物。因此，可以认为该方法可用于分析来自职业环境的样本，因为成功地提取，衍生化，并通过高效液相色谱法，通过高效液相色谱，通过高性能液相色谱法用芳族胺，酚和脂族胺进行硫酸浸渍过滤器。实际上，在没有预处理的情况下，仅量定量地检测芳族胺，没有其他尖刺的化合物被检测到。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35800/'>《Journal of separation science.》</a> <b style="margin: 0 2px;">|</b><span>2018年第23期</span><b style="margin: 0 2px;">|</b><span>共8页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Inoue Naoko&option=202" target="_blank" rel="nofollow">Inoue Naoko;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Work Environment Research GroupJapan (JNIOSH)Tama Kawasaki Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/159.html" title="化学">化学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=carcinogenic aromatic amines&option=203" rel="nofollow">carcinogenic aromatic amines;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=derivation&option=203" rel="nofollow">derivation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=occupational health&option=203" rel="nofollow">occupational health;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=selective reaction&option=203" rel="nofollow">selective reaction;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=workplace&option=203" rel="nofollow">workplace;</a> </p> <div class="translation"> 机译：致癌芳香胺;衍生;职业健康;选择性反应;工作场所;
