Halowax 1051 is the highest chlorinated technical chloronaphthalene mixture among seven known formulations of the Halowax series. Octa- and heptaCN homologue groups are the main CN constituents of Halowax 1051 with declared 90% and 10% contents, respectively. In this study, using an isotope dilution technique and HRGC/HRMS, octaCN and heptaCNs contents of six batches of Halowax 1051 were between 82-93% and 6.2-17%, respectively. Also mono- to hexaCNs were found in Halowax 1051, and their content more or less varied according to the batch; also, the abundance of a particular CN congeners varied. Tetra-, penta- and hexaCNs have been found in all six batches of Halowax 1051 examined, and their contents varied between 0.0024-0.77%, 0.031-0.22%, and 0.21-0.82%, respectively. TriCNs have been found in three of six batches, and mono- and diCNs in two of six batches with 0.0020-0.40, 0.0017-0.25 and 0.0012-0.34% for positive findings, respectively. 2,3-DiCN (no. 10), 1,8-diCN (no. 9) at < 0.0002 mg/g, 1,6,7-/2,3,6-triCNs (nos. 25/26), 1,3,8-triCN (no. 22) at < 0.0002 mg/g, 1,3,6,7-tetra (no. 44), 1,2,3,6-tetra- (no. 29), 1,2,7,8-tetraCN (no. 41) and 1,2,3,6,7,9-hexaCN (no. 70) at < 0.0005 mg/g have not been found in Halowax 1051.
哈洛蜡1051是哈洛蜡系列七种已知配方中氯化程度最高的工业用氯萘混合物。八氯萘和七氯萘同系物组是哈洛蜡1051的主要氯萘成分，宣称含量分别为90%和10%。在本研究中，采用同位素稀释技术和高分辨率气相色谱/高分辨率质谱法，六批哈洛蜡1051的八氯萘和七氯萘含量分别在82 - 93%和6.2 - 17%之间。在哈洛蜡1051中还发现了一氯萘至六氯萘，其含量因批次不同而或多或少有所变化；此外，特定氯萘同系物的丰度也有所不同。在所检测的六批哈洛蜡1051中均发现了四氯萘、五氯萘和六氯萘，其含量分别在0.0024 - 0.77%、0.031 - 0.22%和0.21 - 0.82%之间。在六批中的三批中发现了三氯萘，在六批中的两批中发现了一氯萘和二氯萘，阳性结果的含量分别为0.0020 - 0.40%、0.0017 - 0.25%和0.0012 - 0.34%。在哈洛蜡1051中未发现含量<0.0002 mg/g的2,3 - 二氯萘（编号10）、1,8 - 二氯萘（编号9），含量<0.0002 mg/g的1,6,7 - /2,3,6 - 三氯萘（编号25/26）、1,3,8 - 三氯萘（编号22），含量<0.0005 mg/g的1,3,6,7 - 四氯萘（编号44）、1,2,3,6 - 四氯萘（编号29）、1,2,7,8 - 四氯萘（编号41）和1,2,3,6,7,9 - 六氯萘（编号70）。
