Scope
Scope: This document specifies two methods for determining the residual amounts of dibutyl peroxide (DTBP) and 2,5-dimethyl-2,5-dibutyl peroxide (DBPH) in polypropylene meltblown special materials. This document is applicable to the determination of the residual amounts of dibutyl peroxide (DTBP) and 2,5-dimethyl-2,5-dibutyl peroxide (DBPH) in polypropylene meltblown special materials. Main technical content: The method summary involves dissolving or swelling the sample in a certain volume of tetrahydrofuran solvent, which contains a known amount of n-undecane as an internal standard. A suitable amount of solution is extracted with a micro-injection pump and directly injected into a gas chromatograph or gas chromatography-mass spectrometry instrument for analysis under certain conditions. The quantification is performed using an internal standard curve method.
