Preparation and Evaluation of some Acrylic Acid Derivatives as Corrosion and Scale Inhibitors in Desalination Water Plants.

Abstract

Copper has an excellent electrical and thermal conductivities, good corrosion resistance and mechanical workability. It is widely used in heating and cooling systems. Corrosion of copper can lead to many problems, the most being per formation that may result in coolant leakage. Scales and corrosion products have negative influence on heat-transfer, causing a decrease in heating efficiencies of the copper structures. The use of inorganic or organic inhibitors is one of the most practical methods for protection against corrosion of metals and their alloys. Most well-known organic inhibitors such as those containing nitrogen, sulphur, oxygen atoms and aromatic rings ,So, this work aims to synthesis of a new corrosion and scale inhibitors based on acrylic acid derivatives and evaluation their inhibition efficiency on the copper corrosion in sea water. This work includes three main parts:
