Preface
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 23963-2009 "Diethylamine for Industrial Use". Compared with GB/T 23963-2009, except for structural adjustment and editing
In addition to sexual changes, the main technical changes are as follows.
---Deleted the qualified product indicator and canceled the product grade (see Table 1 of the.2009 version);
---"Diethylamine" was changed from "≥99.5%" (excellent product) to "≥99.7%" (see Table 1, Table 1 of the.2009 version);
---Changed the determination method of moisture (see 5.3, 4.5 of the.2009 edition);
---The "Safety" part has been adjusted to an informative appendix (see Appendix A, Chapter 7 of the.2009 edition).
