[0079] Preparation of oleic acid diethanolamide borate (steady state)

[0080] Oleic acid diethanolamide borate (steady state) is oleic acid diethanolamide borate modified by alkylphenol polyethylene oxide ether salts at a temperature of 120°C. Its structural formula is as follows:

[0081]

[0082] The direct synthesis reaction equation is as follows:

[0083]

[0084]

[0085]

[0086] Add oleic acid into the reaction kettle, heat it to 100°C under the protection of nitrogen, add part of it at the ratio of oleic acid:diethanolamine=1:0.5mol, continue to heat up to 150-155°C, use NaOH standard solution to detect the content of free acid , when the content of free acid is lower than 1.5%, keep warm until the amine value of the reactant no longer changes to the end point. After being cooled to normal temperature, add boric acid in a molar ratio of oleic acid: boric acid = 1: 2, and use concentrated H 2 SO 4 As a catalyst, raise the temperature to 170°C, stir at c...

Abstract

The invention discloses an oil soluble built high effective antirust additive and preparing method, which comprises the following steps: allocating 12-30 wt polyhydroxy carboxylic acids, 40-60 wt oleic acid acetal amide boric acid ester, 3-6 wt bromide triethyl cetyl ammonium, 2-6 wt alkyl group bromine generation ammonium salt, 10-30 wt dioctyl regular sebacate, 20-30 wt trolamine, 0. 7-1. 3 wt wool alcohol; getting the product. This product possesses good oil solubility, which can be used as antirust agent for ferrous metal and non-ferrous metals.

Description

technical field [0001] The invention relates to a high-efficiency anti-rust additive in the field of anti-corrosion and a preparation method thereof, in particular to an oil-soluble compound high-efficiency anti-rust additive with excellent anti-rust performance and environmental friendliness and a preparation method thereof. Background technique [0002] In October 2003, Ke Wei, an academician of the Chinese Academy of Engineering, pointed out in the "China Corrosion Investigation Report" that "the annual direct cost of corrosion in my country has reached more than 200 billion yuan. If indirect losses are considered, the total cost of corrosion is estimated to be up to 500 billion yuan, accounting for about 5% of the total national economy. This is a considerable expenditure, and each citizen pays an average of 500 yuan for corrosion costs per year." [0003] The damage and deterioration caused by the chemical and electrochemical effects of metal parts in their use environme...
