Alkyl phenol polyoxyethylene ether is widely used in textile printing and dyeing processing as the main raw material of wetting, infiltrating, emulsifying and washing agents.
Its impact on the ecological environment mainly refers to its safety and biodegradability. Safety includes acute toxicity, aquatic toxicity, and skin irritation
Sex, teratogenicity and variability. Biodegradability has been paid more attention in recent years, and the printing and dyeing auxiliaries with poor biodegradability will accumulate
It has a serious impact on the environment.
Alkylphenol polyoxyethylene ether, alkylphenol ethoxylates, pancreas bleaching.
Alkyl phenol polyoxyethylene ether is a kind of important non-ionic surfactant, which was first synthesized successfully in 1940(NPEOs) and octyl phenol polyoxyethylene ether (OPEOs) are mainly used as detergents, emulsifiers, dispersants, antioxidants and other widely used in paper pulp
And paper industry cooking and sizing, textile industry wool washing, electronic plastic and rubber processing and other industrial production and washing.
The second category of non-ionic surfactants. Alkyl phenol alkyl carbon atoms can be adjusted, and the number of ethylene oxide can be increased or decreased. But it's used in industry
Nonylphenol was the most common, followed by octyl phenol and dodecyl phenol. It has been developed in the direction of straight chain alkyl phenol polyoxyethylene ether.
Among alkylphenol polyoxyethylene ether (APEO), nonylphenol polyoxyethylene ether (NPEO) is the largest, accounting for over 80%. Then octyl phenol polyoxyethylene ether(OPEO), accounting for more than 15%; Dodecyl polyoxyethylene ether (DPEO) and dinonylphenol polyoxyethylene ether (DNPEO) each account for about 1%.
