GB/T 14022.2-2009Technical furfuryl alcohol test methods (English PDF)

Foreword

GB/T 14022 is divided into two parts.

--- Part 1. Industrial alcohol;

--- Part 2. Test methods for industrial alcohol. This section GB/T 14022 Part 2. GB/T 14022.2-1992 "industrial alcohol test methods" in this section instead. This section compared with the GB/T 14022.2-1992 The main changes are as follows:

--- Increase in moisture content determination "Karl Fischer method" entry;

--- Increasing the alcohol content determination in "gas chromatography (capillary method)" entry;

--- Modify and supplement the "Test Report" entry content. This section of the Appendix A, Appendix B are informative appendices. This part by the State Forestry Administration. This part of the jurisdiction of the Chinese Academy of Forestry Forest Research Institute of Chemical Industry. This section is responsible for drafting unit. Nanjing Forestry University.

1 Scope

GB/T 14022.2-2009 is the Chinese national standard on technical furfuryl alcohol test methods, 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 2009 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 November 2009. Classification: ICS 71.100.99, CCS B72. 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.

This section GB/T 14022 provisions of industrial alcohol (GB/T 14022.1) Test Method. Including appearance, density, refractive index, water Content of cloud point, acidity, aldehyde content, alcohol content. This section applies to industrial furfural (GB/T 1926.1) as a raw material by catalytic hydrogenation to take industrial alcohol.

3 Test Method

3.1 General provisions Tests Unless otherwise specified, the reagents used were of analytical grade. Water as carbon dioxide-free distilled water (according to GB/T 603 specified party Preparation) or equivalent purity water.

3.2 densitometry

3.2.1 pycnometer method At 20 °C constant temperature, the volume of pycnometer Calibration with distilled water, and then determine the mass of the same volume of the sample, find its density, results rho20 (g/mL) indicates.
