Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 339-2001 "Synthetic Phenol for Industrial Use". Compared with GB/T 339-2001, the main technical changes are as follows. --- Updated normative references (see Chapter 2, Chapter 2 of the.2001 edition); --- Removed the "dissolution test [(1.20) absorbance]" (see Tables 1 and 4.3 of the.2001 edition); ---Excellent products add "phenol content" "total organic impurities (except cresol impurities)" "cresol impurities" "melted color" "evaporation residue" 7 indicators such as “iron” and “burning residue” and corresponding analysis methods (see Table 1 and Chapter 4, Table 1 of the.2001 edition); --- The moisture index of superior products and first-class products was changed from “≤0.10%” to “≤500mg/kg”, and the qualified products were added with water projects. It is designated as “reported value” (see Table 1, Table 1 of the.2001 edition); --- Change the difference between the two parallel determinations of "moisture" from "not more than 0.01%" to "not more than 20mg/kg" (see 4.8, 4.4) of the.2001 edition; --- Delete the "Safety" chapter, the relevant content is included in the informative appendix (see Appendix C, Chapter 7 of the.2001 edition). This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Chemical Standardization Technical Committee (SAC/TC63). This standard was drafted. China Petrochemical Co., Ltd. Beijing Yanshan Branch, China Petroleum and Chemical Corporation Beijing Institute of Engineering. Participated in the drafting of this standard. Jilin Petrochemical Company of China National Petroleum Corporation. The main drafters of this standard. Peng Jinrui, Cui Guanghong, Yu Hongjun, Li Xuemei, Shi Anmin, Huang Wei. The previous versions of the standards replaced by this standard are. ---GB/T 339-1964, GB/T 339-1982, GB/T 339-1989, GB/T 339-2001. Industrial synthetic phenol Caution - This standard does not address all possible security issues.
