Foreword

This standard replaces GB/T 4119-1993 "industrial carbon tetrachloride." This standard compared with GB/T 4119-1993 The main changes are as follows. --- By the scope "This standard applies to natural gas thermal chlorination process, carbon disulfide, methanol method and perchlorination chlorine solution produced carbon tetrachloride" Was changed to "This standard applies to methanol and hydrogen chloride gas thermal chlorination process to produce carbon tetrachloride" (GB/T 4119- 1993 Chapter 1, Chapter 1 of this edition); --- Technical requirements, carbon disulfide canceled projects; superior product quality index score by the CTC modify ≥99.8% ≥99.80%, from the first-class goods index ≥99.5% revised to ≥99.50% (GB/T 4119-1993 3.2, this version 3.2); --- Test method, carbon tetrachloride, chloroform, tetrachlorethylene content measured references GB/T 21541-2008 "industrial chlorinated Methane product purity determined by gas chromatography. " Moisture, acidity measured by reference to standard GB/T 4120 is amended as GB/T 4117-2008; increasing the appearance of the test method (GB/T 4119-1993 of Chapter 4, Chapter 4 of this edition); --- Inspection rules and signs, packaging, storage and transport is divided into two chapters to write (GB/T 4119-1993 Chapter 5 of this edition, Chapter 5 And Chapter 6); --- Added "drugs" signs (see 6.1); --- Added "Security" chapter (see Chapter 7).
