Application

甲苯可作为液相色谱-大气压光电离-质谱 (LC-APPIMS)定量分析三酰甘油(TAG)的掺杂剂。据报道，它可以提高分析的灵敏度。也可用作四臂聚丙交酯(PLA)星形低聚体制备溶剂。

General description

甲苯，一种苯类似物，广泛用作有机溶剂。它已被报道是一种具有生物毒性的溶剂（在0.1％v / v浓度对许多微生物有毒）。他通过硝化细菌Thauera arornatica对CO₂的厌氧生物降解作用已被报道。它可形成间同立构聚苯乙烯-甲苯分子化合物。该分子化合物的晶体结构已通过X光衍射而被研究。

Liquid chromatography-atmospheric pressure photoionization-mass spectrometry analysis of triacylglycerol lipids--effects of mobile phases on sensitivity.

Sheng-Suan Cai et al.

Journal of chromatography. A, 1173(1-2), 88-97 (2007-10-30)

In this work, we evaluate the performance of liquid chromatography-atmospheric pressure photoionization-mass spectrometry (LC-APPI-MS) for non-aqueous reversed phase analysis of six triacylglycerol model compounds using six binary mobile phases including MeOH/iPrOH, MeOH/CHCl(3), MeOH/CH(2)Cl(2), CH(3)CN/iPrOH, CH(3)CN/CHCl(3), and CH(3)CN/CH(2)Cl(2).

European journal of biochemistry, 238(3), 661-668 (1996-06-15)

Toluene is degraded anoxically to CO2 by the denitrifying bacterium Thauera aromatica. Toluene first becomes oxidized to benzoyl-CoA by O2-independent reactions. Benzoyl-CoA is then reduced to non-aromatic products by benzoyl-CoA reductase. We set out to study the reactions employed for

Screening for Estrogen Active Nonylphenols in Water by Planar Solid Phase Extraction – Planar Yeast Estrogen Screen

Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
