3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Alkylphenol (AP) alkylphenols The molecular structure of the alkylphenol R-C6H4-OH. This type of common substances are octyl phenol (C8H17-C6H4-OH, abbreviated OP) and azelaic Phenol (C9H19-C6H4-OH, referred to as NP). 3.2 Alkyl phenol ethoxylates (APEO) alkylphenolpolyethoxylates The molecular structure of alkylphenol ether is R-C6H4- (OC2H4) nOH; n = 2 ~ 16,17 ~ 34,35 ~ 45. The substances Common are octyl phenol ethoxylates [C8H17-C6H4- (OC2H4) nOH, referred OPnEO] and nonylphenol ether [C9H19- C6H4- (OC2H4) nOH, referred NPnEO]. NOTE. alkyl phenol ethoxylates as waterborne coatings surfactant. Alkylphenols are degradation products of alkylphenol ethoxylates. Principle 4 Methanol and water as the extraction solvent, centrifugal separation and Soxhlet extraction method of combining the extracted sample APEO, the extract was concentrated After the treatment, the use of high performance liquid chromatography or precision to meet current and effective methods (such as. liquid chromatography - mass spectrometry, liquid chromatography - tandem mass spectrometry Etc.) were detected. The average adduct number ethoxylates APEO determine and reversed-phase liquid chromatography to determine the APEO using normal phase liquid chromatography Determination of content combining external standard. Note. The extraction of the sample may also be used to select another APEO confirmed a considerable recovery of extraction methods, such as high-speed centrifugation, ultrasonic extraction.

5 Reagents and materials
