What is Potassium titanium oxalate?

Potassium titanium oxalate, also known as potassium oxalate, is a potassium salt complex formed by titanium and oxalic acid. It belongs to organotitanium compounds, and its chemical formula is usually written as:

K2TiO(C2O4)2·2H2O (C4H4K2O11Ti, CAS No.: 14481-26-6, EINECS No.: 238-475-3, molecular weight approx. 354.19)

It is a white or off-white crystalline powder at room temperature, soluble in water, insoluble in ethanol, and its aqueous solution is acidic. Potassium titanium oxalate is prepared by complexing oxalic acid with titanium salt in the presence of potassium salt, and is a stable titanium oxalate complex.

From a molecular structure perspective, potassium titanium oxalate contains a titanium oxide group (Ti=O) and two oxalate ions (C2O4²-), forming a stable five-membered ring chelate structure with the titanium ions. This structure allows it to slowly dissociate into active titanium species in aqueous solution, which can be used as a tanning agent to bind with leather collagen, as a mordant to coordinate with dyes, and as a titanium source in the synthesis of functional materials. This characteristic of "stable complexation + controlled release of titanium" forms the basis for its widespread application in fields such as leather, textiles, surface treatment, and materials research.

Chemically, potassium titanium oxalate is stable in air, soluble in water to form an acidic solution, and decomposes upon heating; its aqueous solution contains titanium, which exhibits flocculation and complexing activity. It should be stored in a dry, sealed container.

Non-industrial grade potassium titanium oxalate refers to products geared towards research, process, and consumer applications, primarily including reagent-grade specifications, with a purity generally above 99%. Compared to industrial grade, non-industrial grade products place greater emphasis on the following indicators:

Purity and Impurity Control

Reagent-grade reagents generally require control of metallic impurities such as iron to ensure the quality of experimental and process applications.

Titanium content

Titanium content is a core indicator for measuring product quality, and it directly affects the effects of tanning, mordant dyeing, and material synthesis.

Solubility

It is required that the solution dissolves quickly in water and is clear, so as to ensure the stability of reagent preparation and process application.

Moisture

Excessive moisture content affects measurement accuracy and storage stability, and must be kept at a low level.

What are the uses of Potassium titanium oxalate?

1. Scientific research and laboratory applications (reagent grade, core applications)

Potassium titanium oxalate is a commonly used titanium source and analytical reagent in laboratories. It is used for titanium content determination, titanium complex chemistry research, and is also an important precursor for the synthesis of electronic ceramic materials such as barium titanate and titanium-based functional materials. It is a commonly used reagent in materials and chemistry laboratories.

2. Textile mordant dyeing process (process grade)

Potassium titanium oxalate is used as a mordant and brightener in printing and dyeing to help dyes fix on fibers, improve color fastness and color, and is applied in hand printing and dyeing, natural dyeing and textile processing.

3. Metal and Stone Surface Treatment (Consumer Grade)

Utilizing the surface treatment capabilities of potassium titanium oxalate, it can be used for surface treatment of metal parts before painting and for whitening and polishing stone surfaces, helping DIY enthusiasts and craftspeople achieve a smooth and bright surface effect.

4. Leather Tanning (Core Application)

Potassium titanium oxalate is the core raw material of environmentally friendly titanium tanning agents. It is used in leather tanning, and the tanned leather is white, soft and full, elastic, and resistant to light, washing and abrasion. The bare leather absorbs the tanning liquor completely. It can be used as an environmentally friendly alternative to chromium tanning agents and is applied in the production of shoe upper leather, clothing leather and bag leather.

5. Marble Surface Treatment

Potassium titanium oxalate is used as a surface treatment agent for marble and other stones to help whiten and brighten the stone surface, and is applied in the processing and maintenance of building stone.

6. Catalyst

Potassium titanium oxalate and its derivatives can be used as catalyst components in some chemical reactions, and are applied to organic synthesis and fine chemical reactions due to the coordination activity of titanium.

7. Electronic ceramic precursors

Potassium titanate is an important precursor for the synthesis of electronic ceramic powders such as barium titanate and strontium titanate. Barium titanate is used to manufacture electronic components such as MLCC capacitors, PTC thermistors and sensors, and is an important raw material in the electronic materials industry chain.

8. Teaching and Popular Science Experiments

Potassium titanium oxalate can be used in teaching demonstrations and experiments in coordination chemistry to help students understand the complexation reaction of titanium and the coordination chemistry of oxalic acid. It is a commonly used teaching reagent in university chemistry laboratories.

9. Functional Materials Research (Research Level)

Potassium titanium oxalate is an important precursor for the preparation of electronic ceramic powders such as barium titanate and strontium titanate, as well as photocatalytic titanium materials. Research institutions use high-purity potassium titanium oxalate to develop new functional materials to serve electronic and new energy research.

10. Other Applications

With the development of materials science research, the application scope of non-industrial grade potassium titanium oxalate continues to expand, including areas such as custom synthesis, standard reagent supply, and analytical testing services.

It should be noted that non-industrial grade specifications do not mean "risk-free": potassium titanium oxalate contains oxalate, which can be irritating to the skin and eyes. When using reagent-grade products in experiments, laboratory safety regulations should be followed, protective equipment should be worn, and dust inhalation and skin contact should be avoided.

Summarize

Potassium titanium oxalate is a white crystalline powder of titanium oxalate complex. It is acidic when soluble in water. Through its stable complexation and controlled release of titanium, it serves as a core raw material for environmentally friendly titanium tanning agents, as well as a mordant, surface treatment agent, and precursor for functional materials. In daily life, we indirectly encounter it through leather products, metal casings of home appliances and automobiles, textile dyeing products, marble building materials, electronic ceramic devices, and testing laboratories. In non-industrial applications, reagent-grade potassium titanium oxalate is widely used in scientific research and laboratories, textile mordant processes, metal and stone surface treatment, functional ceramic materials research, and teaching experiments. It is an important organic titanium compound connecting "daily use" with "scientific research, processes, and materials."
