GB/T 28611-2012O-Nitrotoluene, p-Nitrotoluene (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard uses redrafted law revision by the Japanese Industrial Standards JISK4108:1995 "nitrobenzene" (nitrobenzene, o-nitrotoluene, Nitrotoluene,).

This standard JISK4108. Compared to 1995, the restructuring is as follows.

--- Increased in Chapter 4;

--- The JISK4108:1995 Chapter 4, Chapter 5 of imputation Chapter 5, Chapter 6;

--- Removed JISK4108:1995 Chapter 6;

--- Increased Chapter 7, Chapter 8.

This standard JISK4108. Compared to 1995, the technical differences are as follows.

--- Deleted nitrobenzene, nitrotoluene content [see JISK4108:1995 5.5 (1), 5.5 (3)];

--- Increasing the product quality grading requirements (see Chapter 3, JISK4108. Chapter 3, 1995);

--- The JISK4108:1995 packed column, stationary phase is polyethylene glycol to modify FFAP capillary column stationary phase (14% Cyanopropyl phenyl) - methyl polysiloxane (see 6.3.3, JISK4108:1995's 5.5 2.2.4);

--- The JISK4108:1995 corrected peak area normalization method to modify the peak area normalization method (see 6.3.6, JISK4108.

1995 5.5 2.5);

--- Deleted the melting point, crystallization point and non-volatile content (see JISK4108:1995 Chapter 3, 5.3, 5.4, 5.7).

This standard made the following editorial changes.

--- Standard name from "nitrobenzene (nitrobenzene, nitrotoluene, inter-nitro toluene, nitrotoluene)" was changed to "o, nitromethane benzene".
