preparation example Construction

[0045] The preparation method of the n-heptanoic acid triisopropanolamine soap of the present application may further comprise the steps:

[0046] (1) Putting n-heptanoic acid of 18% to 25% in mass percentage into the reactor, heating up to 80°C, for subsequent use;

[0047] (2) Slowly drop triisopropanolamine with a mass percentage of 75% to 82% into the reactor, and react at 110 to 130°C for 2 to 4 hours,

[0048] (3) stop heating, naturally cool to room temperature, discharge, be triisopropanolamine n-heptanoate soap.

Embodiment 1

[0051] The embodiment of the present application provides the preparation method of the first triisopropanolamine n-heptanoate soap:

[0052] (1) 21% n-heptanoic acid is dropped into the reactor, and the temperature is raised to 80° C. for subsequent use;

[0053] (2) slowly drop 79% triisopropanolamine into the reactor, and react at 125° C. for 3 hours,

[0054] (3) stop heating, naturally cool to room temperature, discharge, mark as embodiment 1.

[0055] The N-heptanoic acid triisopropanolamine soap prepared by the embodiment of the present application is detected by infrared spectrogram and proton nuclear magnetic resonance spectrum, and the results are as follows: Figure 1~2 as shown, Figure 1~2 Illustrate that the embodiment of the present application successfully prepares triisopropanolamine n-heptanoate soap.

Embodiment 2

[0057] The embodiment of the present application provides the preparation method of the second triisopropanolamine n-heptanoate soap:

[0058] (1) 18% n-heptanoic acid is dropped into the reactor, and the temperature is raised to 80° C. for subsequent use;

[0059] (2) Slowly drop 82% triisopropanolamine into the reactor, react at 125°C for 3h,

[0060](3) stop heating, naturally cool to room temperature, discharge, mark as embodiment 2.

Abstract

The invention belongs to the technical field of surfactants, and particularly relates to triisopropanolamine n-heptanoate soap, a preparation method and application thereof and a metal cleaning agent.The first aspect of the invention provides triisopropanolamine n-heptanoate soap. The structural formula of the triisopropanolamine n-heptanoate soap is shown as a formula I in the specification. Thesecond aspect of the invention provides a preparation method of the triisopropanolamine n-heptanoate soap, which comprises the following step: carrying out heating reaction on n-heptanoic acid and triisopropanolamine to obtain the triisopropanolamine n-heptanoate soap. The third aspect of the invention provides a metal cleaning agent. The metal cleaning agent comprises triisopropanolamine n-heptanoate soap. According to the triisopropanolamine n-heptanoate soap as well as the preparation method and application thereof and the metal cleaning agent, the defects that an existing surfactant usually cannot have rust prevention, lubrication, cleaning, no / low foam, alkali resistance and hard water resistance at the same time can be effectively overcome.

Description

technical field [0001] The application belongs to the technical field of surfactants, in particular to a triisopropanolamine n-heptanoate soap, a preparation method and application thereof, and a metal cleaning agent. Background technique [0002] Metal cleaning is one of the indispensable processes in modern industrial production. It is aimed at cleaning and washing before and after metal processing and during the use of metal equipment. The presence of dirt not only affects the appearance quality, performance and life of the product, but also affects the entire process when it is serious. [0003] Currently commonly used metal cleaning agents are generally divided into solvent-based, semi-solvent-based and water-based. Solvent-based cleaning mainly relies on organic solvents to dissolve dirt to achieve the purpose of cleaning. Its cleaning effect is good, but it is volatile, has low flash point, strong toxicity, and produces a large amount of VOC emissions, which is not e...
