3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 In cereal grains, potatoes, fruits and other raw materials, produced by fermentation obtained acetic acid (glacial acetic acid). 3.2 In hydrocarbon acetylene, ethylene, methanol and other petrochemical products as raw materials, synthetic production obtained in acetic acid (glacial acetic acid). Principle 4 Brewing acetic 14C content is stable within a certain range, while a large number of synthetic acetic acid 14C decay, only a trace remaining. based on Carbon isotope 14C content in brewing and acetic acid in the synthesis is significantly different measured 14C content of acetic acid by liquid scintillation method to brewing 14C is made of acetic acid 100 acetic acid synthesis is 0,14C 14C content in a mixture of both in their intermediate values \u200b\u200bcan be measured both quantitatively The ratio, as a method of identification.
