1 Scope

This part of SN/T 1850 specifies high performance liquid chromatography for the determination of alkylphenols and alkylphenol ethoxylates in textiles. method. This section applies to the determination of alkylphenols and alkylphenol ethoxylates in textiles.

2 Terms and definitions

The following terms and definitions apply to this part of the SN/T 1850. 2.1 The molecular structure of the alkylphenols is. R-C6H4-OH. Common substances in this class are octylphenol (C8H17-C6H4-OH) and sulfhydryl groups. Phenol (C9H19-C6H4-OH). 2.2 The molecular structure of the alkylphenol ethoxylates is. R-C6H4-(OC2H4)nOH. Octylphenol poly Oxyethylene vinyl ether [C8H17-C6H4-(OC2H4)nOH] and nonylphenol polyoxyethylene ether [C9H19-C6H4-(OC2H4)nOH]. Alkylphenol ethoxylates can be used as surfactants in textiles, and alkylphenols are alkylphenol ethoxylates. Degradation products.

3 Principle
