Problems solved by technology

However, in the titanium organic acid synthesized by this metathesis reaction, the incorporation of different ions cannot be avoided, which reduces the semiconductor performance of titanium oxide.
In this case, in order to remove different kinds of ions, a purification step is required, which increases the number of steps and reduces manufacturability

Embodiment 1

[0048] Add 135.4 g of octanoic acid (0.94 mol, NAA-82, NOF Corporation) to a four-neck flask equipped with a thermometer, a nitrogen inlet tube, a moisture quantitative receiver with a cooling tube, and stirring blades, while nitrogen bubbling is carried out. Add 106.6 g of titanium tetra-n-butoxide (0.32 mol, Orgatix TA-25, Matsumoto Fine Chemical Co., Ltd.), pressurize to 100 mmHg with a vacuum pump, and heat and stir at 95°C. The distilled amount of 1-butanol per hour was 0.100 mol / mol·h, and the total distilled amount was 0.390 mol / mol. The distillate disappeared, and a brown fatty acid titanium solution was obtained.

Embodiment 2

[0050] Using the reaction device and reaction raw materials described in Example 1, nitrogen gas was bubbled at 300 ml / min, and heated and stirred at 95° C. under normal pressure. The distilled amount of 1-butanol per hour was 0.026 mol / mol·h, and the total distilled amount was 0.320 mol / mol. The distillate disappeared, and a brown fatty acid titanium solution was obtained.

Embodiment 3

[0052] Using the reaction device and reaction raw materials described in Example 1, nitrogen gas was bubbled at 100 ml / min, and heated and stirred at 95° C. under normal pressure. The distilled amount of 1-butanol per hour was 0.020 mol / mol·h, and the total distilled amount was 0.320 mol / mol. The distillate disappeared, and a brown fatty acid titanium solution was obtained.

Abstract

In the invention, fatty acid titanium with low viscosity and high titanium content is obtained through the reaction of fatty acid and titanium tetraalkoxide under specific conditions. The present invention generates fatty acid titanium by reacting monobasic fatty acid with 4-10 carbon atoms and titanium tetraalkoxide composed of alkoxides with 1-6 carbon atoms under heating. At this time, the amount of fatty acid added to 1 mole of titanium tetraalkoxide is 2.0 to 3.5 moles, and the reaction temperature is 85 to 110°C. The reaction was carried out while removing alcohol distilled out from the reaction system in an amount.

Description

technical field [0001] The invention relates to a preparation method of fatty acid titanium. Background technique [0002] Titanium oxide exhibits excellent properties as a semiconductor and can be used as a variety of materials such as photocatalysts, ferroelectrics, and piezoelectric elements, so titanium oxide thin films are actively being developed. As a method for forming a titanium oxide thin film, a vacuum evaporation method, a sputtering method, a CVD method, etc. are mentioned as a vapor phase growth method. These methods all require large-scale equipment, and require high-cost and technically difficult conditions such as high vacuum and high temperature. On the other hand, in the liquid phase growth method, a thin film can be formed with relatively cheap equipment and easy conditions. [0003] As a method of forming a titanium oxide thin film using a liquid phase growth method, a sol-gel method utilizing hydrolysis of a titanium alkoxide is known. The sol-gel me...
