3 Terms and Definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
alkylphenols, referred to as AP
the molecular structure of alkylphenols is: R-C6H4-OH. Common substances of this class are octylphenol (C8H17-C6H4-OH, referred to as OP) and nonylphenol (C9H19-C5H4-OH, referred to as NP)
3.2
alkylphenol polyethoxylates, referred to as APEO
the molecular structure formula of alkylphenol polyethoxylates is: R-C6H4-(OC2H4)nOH. Common substances of this class are octylphenol ethoxylate [C8H17-C6H4-(OC2H4)nOH], referred to as OPEO and nonylphenol ethoxylate [C9H19-C6H4-(OC2H4)nOH], referred to as NPEO
Alkylphenol polyethoxylates can be used as the surfactant in textile dyeing and finishing auxiliaries, and alkylphenols are degradation products of alkylphenol polyethoxylates
