GB/T 15354-2011Chemical reagent - Tributyl phosphate (English PDF)

Foreword

This standard replaces GB/T 15354-1994 "Chemicals tributyl phosphate", compared with the GB/T 15354-1994 major changes as follows:

--- Acidity of the unit by the "mmol/100g" adjusted "mmol/g" (1994 edition 3.3, this version of Chapter 4);

--- Modify the packaging and logo (the 1994 edition of Chapter 6, Chapter 7 of this edition). The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee Chemistry Chemicals Branch (SAC/TC63/SC3) centralized. This standard was drafted. Lee Longbo China (Tianjin) Pharmaceutical Chemical Co., Ltd. The main drafters of this standard. Wang Xu, Juan. This standard was first published in 1994, this is the first revision. Chemicals tributyl phosphate Exemplary formula. (CH3CH2CH2CH2O) 3PO Molecular weight. 266.32 (according to 2007 international relative atomic mass)

1 Scope

GB/T 15354-2011 is the Chinese national standard on chemical reagent - tributyl phosphate, in the field of chemical technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 12 May 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2011. Classification: ICS 71.040.30, CCS G63. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
