The standard is revised from the chemical industry standard HG/T 203491.L lithium megaacetate. The main technical differences between this standard and HGI 2044 are as follows: military, daily heavy metals (measured in Pb), zinc item after. The name of the test ammonium precipitate (in terms of sodium chloride) was changed to gold reduction and gold screen: the oxidation number (in terms of I> index of superior products was changed from less than or equal to 0.003% to less than or equal to + C.C02%, and the guarantee index was increased. The superior products, first-class products and qualified products were all less than 0.08%. The determination method provided was changed from the visual colorimetric method to the hand absorption spectrometry method. From the implementation of the standard in 2001, it replaced 1IG/T3034-91. This standard was proposed by the National Technical Committee on Chemical Standardization. This standard is under the jurisdiction of the National Technical Committee on Chemical Standardization: The unit that drafted this standard is Dalian Juxing Organic Chemical Co., Ltd. (the first organic chemical factory of the People's Republic of China). The participating drafting units of this standard are Nanjing Chemical Reagent Factory, Yizheng Chemical Fiber Lairun Special Chemicals Co., Ltd., Liaoyang Hongwei Heying Energy Co., Ltd. This standard mainly involves the planning and design of the standard, and the standard is entrusted to the organic branch of the Chemical Standardization Technical Committee of the People's Republic of China for interpretation. 41

When there are special requirements, the preparation shall be in accordance with GB/T601.GB/T632.GH603. 4.1. Sub-determination of acetaldehyde manganese content. 4.1. Method: In the presence of oxygen-activated buffer solution, the sample is titrated with FDTA standard titration, and the change in the color of the indicator is used to determine the full point of the titration: the content of acetic acid is calculated based on the volume of the consumed standard titration solution. 4.2. Test solution. 4.2. 1. Pick cyclohexane,

4.1.3 Analysis steps
Weigh 0.6g of sample (accurate c.0902g) into 250ml of water, add 130ml of water, titrate with about 20% chromium hydroxide standard solution, add 0.1g ascorbic acid, 1mL ammonium hydroxide solution and 2 drops of chromium black indicator solution, continue titrating until the color of the solution decreases from red to blue, which is the flash point. The blank test was carried out in the same way. 4.1.4 Analysis results were expressed as a percentage of the original amount of acetic acid short [in terms of Ma (CIIC (O)); 4H, O containing (X, calculated according to formula (1)
