The method on trans fatty acids analysis in food is very important. The effects of methylate sodium, potassium hydroxide, sulfuric acid and boron trifluoride in methanol and their different concentration and dosage on TFA analysis were studied. The chromatographic condition and the influence of time and temperature on the esterifation of TFA using boron trifluoride in methanol were optimized. A method for analyzing TFA were established by GC based on boron trifluoride in methanol and RT-2560(100m×0.25mm×0.2μm) capillary column.

The results show that the originated materials for electrolyte aluminium is Al2O3 and AlF3 has good property to absorb vapour. After the water contained in the originated materials goes into electrolyte, AlF3 reacts with water hydrolyzed and the rest of water is electrolyzed into hydrogen and oxygen. Hydrogen enteres aluminum liquid by diffusing and autoecious in Al2O3, which is the main source of hydrogen in electrolyte aluminum liquid.
