T/CSTM 00862-2023 Nonaqueous dispersant 2,2'-methylenebis(4,6-di-tert-butylphenyl) phosphate sodium salt

Scope

Scope: This document specifies the molecular formula, structural formula, relative molecular mass, CAS number, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of the nucleating agent 2,2’-methylene bis-(4,6-di-tert-butylphenyl) phosphate sodium salt. This document is applicable to the inspection of the nucleating agent 2,2’-methylene bis-(4,6-di-tert-butylphenyl) phosphate sodium salt, which is prepared from 2,4-di-tert-butylphenol, formaldehyde, phosphorus trichloride, and sodium hydroxide as the main raw materials, through the substitution of chlorides with diphenols and aromatic phosphoric acids, followed by a salting reaction.
