Problems solved by technology

However, research in recent years has found that most of the vulcanized animal and vegetable oils used in the lubricant market are brown or even darker due to the influence of the selected raw materials for preparation and reaction conditions, etc. color, and the effect of compounding it with hydrogenated base oil is not good
Such as: such additives have poor oil solubility in hydrogenated base oil due to their own chemical structure; in addition, because their color is too dark, it seriously affects the overall color of the oil, etc.
It is precisely because of the existence of the above-mentioned defects that on the one hand, the effect of high-quality oil cannot be achieved, and on the other hand, its application field is also greatly restricted.

Embodiment 1

[0035] In the first embodiment, the molar ratio of erucic acid: sulfur monochloride is 1:0.9.

[0036] Specific steps are as follows:

[0037] Step 1. Weigh erucic acid, pour it into a flask, and place the flask in a constant temperature water bath (the temperature is controlled at 15±1°C);

[0038] Step 2. Add sulfur monochloride dropwise through the separatory funnel, stir at 600 r / min, carry out low-temperature vulcanization, and react until there are no more bubbles at the catheter port where the sodium hydroxide solution (mass percentage concentration is 20%) is introduced. After generating, stop the reaction after reacting for 15 minutes;

[0039] Step 3, the product is fully washed with 5% sodium hydroxide solution, and the water layer is removed after standing for liquid separation;

[0040] Step 4, wash twice with distilled water;

[0041] Step 5, decompression distillation to obtain light yellow sulfurized erucic acid product 1#.

Embodiment 2

[0043] In the second embodiment, the molar ratio of erucic acid: sulfur monochloride is 1:1.

[0044] Specific steps are as follows:

[0045] Step 1. Weigh erucic acid, pour it into a flask, and place the flask in a constant temperature water bath (the temperature is controlled at 20±1°C);

[0046] Step 2. Add sulfur monochloride drop by drop through the separatory funnel, stir at 650 rpm, carry out low-temperature vulcanization, and react until there are no more bubbles at the conduit port where the sodium hydroxide solution (mass percentage concentration is 15%) is introduced. After generating, stop the reaction after reacting for 15 minutes;

[0047] Step 3, the product is fully washed with 10% sodium hydroxide solution, and the water layer is removed after standing for liquid separation;

[0048] Step 4, wash twice with distilled water;

[0049] Step 5, decompression distillation to obtain light yellow sulfurized erucic acid product 2#.

Embodiment 3

[0051] In Example 3, the molar ratio of erucic acid: sulfur monochloride is 1:2.

[0052] Specific steps are as follows:

[0053] Step 1. Weigh erucic acid, pour it into a flask, and place the flask in a constant temperature water bath (the temperature is controlled at 25±1°C);

[0054] Step 2: Add sulfur monochloride drop by drop through the separatory funnel, stir at 600 rpm, carry out low-temperature vulcanization, and react until there are no more bubbles at the conduit port where the sodium hydroxide solution (mass percentage concentration is 15%) is introduced After generating, stop the reaction after reacting for 15 minutes;

[0055] Step 3, the product is fully washed with 5% sodium hydroxide solution, and the water layer is removed after standing for liquid separation;

[0056] Step 4, wash twice with distilled water;

[0057] Step five, depressurization distillation obtains light yellow sulfurized erucic acid product 3#.

Abstract

The invention provides sulfurized erucic acid as well as a preparation method and application thereof. Sulfurized erucic acid has a chemical structure formula as shown in the specification and is prepared by performing low-temperature sulfurization reaction on sulfur monochloride and erucic acid in the presence of protection gas. Sulfurized erucic acid provided by the invention is light in color and excellent in anti-wear and anti-friction performances, and has excellent oil solubility in whether protection synthetic oil of base oil I or protection synthetic oil of base oil II or above.

Description

technical field [0001] The invention relates to the field of chemical synthesis, in particular to a sulfurized erucic acid and its preparation method and application. Background technique [0002] As far as the existing technology is concerned, in the field of lubricants, the development of lubricating oil will definitely promote the development of base oil to high quality. In order to meet the high quality, high energy saving, extended oil drain period and low emission requirements of high-grade lubricating oil, the base oil is required to have the characteristics of low viscosity, low volatility, high viscosity index, good anti-oxidation stability and so on. [0003] The hydrogenated base oil changes the chemical composition of the base oil through the hydrogenation process (hydrotreating, hydrocracking, hydroisomerization, hydrofinishing, catalytic dewaxing), which brings many advantages , Such as: high viscosity index, good low temperature performance, good viscosity-te...
