Scope
GB/T 24801-2019 is the English-translated version of 防焦剂 N-环己基硫代邻苯二甲酰亚胺（CTP）.
GB/T 24801-2019 sets the technical requirements, test methods, inspection rules, marking, packaging, transport and storage for the rubber anti-scorching agent N-cyclohexylthiophthalimide, known as CTP.
It applies to CTP made by condensing cyclohexylsulfenyl chloride with phthalimide; the product has the formula C14H15NO2S, a relative molecular mass of 261.28 and CAS registry number 17796-82-6, and its technical requirements are gathered in a single table.
Compared with the previous edition it adds the CAS number and a purity requirement, makes the initial melting point determination the arbitration method, adds an instrumental method for that measurement and drops the active ingredient content.
It cites GB/T 617-2006, GB/T 11409-2008 and GB/T 16631 for the analyses. It replaces GB/T 24801-2009, was issued on 18 October 2019 and has applied since 1 September 2020.

Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 24801-2009 "rubber anti-focus agent CTP", compared with GB/T 24801-2009, except editorial modification In addition, the main technical changes are as follows.
--- Added CASRN (see Chapter 1);
--- The method of determining the initial melting point is legally determined as the arbitration method (see 4.3.1);
--- Increase the initial melting point of the instrument method (see 4.3.2);
--- Removed the technical requirements and test methods for "active ingredient content" (see 4.6 of the 2009 edition);
--- Increased the technical requirements and test methods of "purity" (see 4.7);
--- Added an informative appendix on safety (see Appendix A).
