Abstract

The invention relates to the technical field of acetate production, and discloses a natural plant extract modified compound corrosion inhibitor, which comprises the following components: a glycidyl ester polymer and 2-phosphonobutane-1, 2, 4-tricarboxylic acid, and the glycidyl ester polymer is a product formed by copolymerization of a sugarcane leaf extract and glycidyl methacrylate. The invention also relates to a preparation method of the corrosive agent. According to the corrosion inhibitor disclosed by the invention, natural plant extracts are modified and then are compounded with 2-phosphonobutane-1, 2, 4-tricarboxylic acid for use, so that a synergistic effect can be exerted, the high temperature resistance of the corrosion inhibitor is improved, and a better corrosion inhibition effect is obtained.

Description

technical field [0001] The invention relates to the technical field of acetate production, in particular to a natural plant extract modified compound corrosion inhibitor, a preparation method and application thereof. Background technique [0002] Acetate products are widely used in the fields of solvents, plasticizers, surfactants and polymer monomers. Due to the use of acetic acid and acid catalysts in the production process of acetate, the acidity of the reaction system is high and the material is highly corrosive. Long-term operation of equipment may be damaged by corrosion, shorten the service life, and endanger production safety. Therefore, it is necessary to use an efficient corrosion inhibitor in the production process to reduce the corrosion of acetate production equipment, prolong the service life and ensure production safety. [0003] Corrosion inhibitors are generally divided into two categories: inorganic substances and organic substances according to their com...
