Abstract

Nonyphenols, especially the ethoxylated derivatives of nonylphenol (NPE) known as ethoxylated alkylphenols (APEs), are synthesized for their surfactant properties, which allow a better dispersion of liquids and the miscibility of certain substances such as oil and water. More than 40 years have been used as detergents, emulsifiers, wetting agents and dispersing agents and even cosmetic products such as shampoos. These organic molecules are very persistent and well known by their predatory toxicities on the skin, the eye, the respiratory tract, the kidneys and the liver, they are endocrine disruptors. The textile industry via some ennobling chemicals, tissue contamination and liquid discharges by these molecules remains a concern for the industry and the quality of these discharges. Our goal is to verify the contamination of liquid discharges from a textile industry using certain chemicals in the dyeing process.

Introduction

Nonylphenols (NP) are synthetic organic molecules belonging to the family of alkylphenols. Nonylphenols (NP) constitute a family of chemical compounds of formula C6H4(OH)C9H19 having a benzene ring and a linear or branched carbon a 9 carbon chain, the degree of branching and their positions are very variable according to the isomers. These molecules are present in the form of a pale yellow viscous liquid that gives off a slight phenolic odor. They are usually available in solution with impurities (including dinonylphenol), with commercial mix formulations (nonylphenol/dinonylphenol). Large amounts of nonylphenols are used to produce nonylphenol ethoxylates, which are then incorporated into formulations, and which are not stable in the environment, they are rapidly degraded to Nonylphenol (NP). They are used extensively as detergent precursors, as fuel additives and lubricants, as polymers, such as phenolic resins, in perfumes, such as thermoplastic elastomers, antioxidants, flame retardant materials.

The main compounds of nonylphenols (NP)

• Linear n-nonylphenols: a mixture of isomers of nonylphenols whose alkyl chain is linear (Figure 1).
