Thermometers are filled with fluids such as toluene or alcohol .
温度计装有甲苯或酒精。
Why don 't you deal toluene any more ?
你为什么不再做甲苯生意了?
Paraffin-based candles produced clear sharp peaks for many products such as toluene , which can cause dizziness , and benzene , a carcinogen also found in tobacco smoke .
However , burning candles does not produce high enough temperatures to completely burn the heavy molecules contained in paraffin wax causing the formation and emission of hazardous molecules like toluene , and benzene .
It typically contains catalysts , surfactants , formaldehyde , benzene and toluene -- all culprits for the potential health hazards listed in the materials safety data sheet ( msds ) posted by manufacturers .
" That creates 2000 tons of co2 , and benzol , toluene and other carcinogens are released in the process , " says lin sung-chin , of the county 's environmental protection bureau .
台北县环保局的林松槿表示:“这些纸钱产生了2000吨二氧化碳、苯、甲苯和其它致癌物质。”
The development conditions of toluene disproportionation and transalkylation to prepare p-xylene , light paraffin aromatization were introduced emphatically .
着重介绍了甲苯歧化和烷基转移制取对二甲苯,还有轻质烷烃芳构化的进展情况。
The dynamic gas phase photocatalytic degradation of toluene , benzene and chloroform ( three volatile organic compounds ) was studied in relatively dry condition , and the influences of inlet concentration , flow rate ( retention time ) , photocatalyst and light source were investigated .
The quantitative account shows that the diffusivity increases 4 % - 7 % , magnetic field have no effect on the molecular mass-transfer process of benzene , toluene , acetone and methyl ethyl ketone in the air .
