1. Basic Information and Parameters

Cellulose Diacetate with the CAS number 9035 - 69 - 2 is a widely - used chemical compound. It is an ester formed by the reaction of cellulose with acetic acid. Our factory offers this product at a low price while maintaining high quality.

**Physical Properties**:
- It usually appears as a white to off - white powder or granules.
- It has a certain degree of solubility in organic solvents such as acetone and dichloromethane, but is insoluble in water.
- The density of Cellulose Diacetate is approximately in the range of 1.2 - 1.3 g/cm³.
- Its melting point is around 230 - 300 °C, which makes it stable under normal processing temperatures in many industrial applications.

**Chemical Properties**:
- It is relatively stable under normal conditions. However, it can react with strong acids and alkalis, which may cause hydrolysis of the acetate groups.
- It has good chemical resistance to some common chemicals, which allows it to be used in various chemical environments.

2. Product Uses

Cellulose Diacetate has a wide range of applications in different industries:

**Textile Industry**:
- It is used to produce acetate fibers. These fibers are known for their softness, luster, and good dyeability. Acetate fibers are often used in the production of high - quality clothing, such as dresses, blouses, and linings.
- It can also be blended with other fibers like cotton and polyester to improve the properties of the fabric, such as its drape and moisture - wicking ability.

**Filtration Industry**:
- Cellulose Diacetate membranes are used for microfiltration and ultrafiltration. These membranes have uniform pore sizes, which can effectively separate particles and macromolecules in solutions. They are widely used in the pharmaceutical, food and beverage, and water treatment industries.

**Packaging Industry**:
- It can be made into films for packaging applications. These films have good transparency, flexibility, and barrier properties against oxygen and moisture. They are suitable for packaging food, drugs, and other sensitive products.

3. Product Usage

**Dissolving and Processing**:
- When using Cellulose Diacetate, it is often first dissolved in a suitable organic solvent. Acetone is a commonly used solvent. In a well - ventilated area, slowly add the product to the solvent while stirring continuously until it is completely dissolved. The concentration of the solution depends on the specific application.
- After dissolution, the solution can be used for processes such as spinning to make fibers, casting to make films, or coating.

**Safety Precautions**:
- Wear appropriate personal protective equipment, such as gloves and goggles, when handling Cellulose Diacetate.
- Since it is flammable when exposed to heat, open flames, or strong oxidants, keep it away from these sources.
- Avoid inhaling dust or fumes. If inhalation occurs, move the person to fresh air immediately. In case of contact with eyes or skin, rinse thoroughly with plenty of water and seek medical advice if necessary.

4. Usage Case Studies

**Textile Manufacturing Case**:
- A textile company wanted to produce a new line of high - end women's dresses. They used our Cellulose Diacetate to produce acetate fibers. By carefully controlling the spinning process, they were able to obtain fibers with excellent luster and softness. The dresses made from these fibers were well - received in the market due to their elegant appearance and comfortable wearing experience. The company also found that the dyeability of the acetate fibers was very good, which allowed them to create a wide range of colors for their products.

**Water Treatment Case**:
- A water treatment plant needed to improve the filtration efficiency of its system. They installed Cellulose Diacetate membranes in their microfiltration units. The membranes effectively removed suspended solids, bacteria, and some macromolecules from the water. As a result, the quality of the treated water was significantly improved, meeting the strict standards for industrial and domestic use. The long - term stability and low cost of replacement of these membranes also brought economic benefits to the water treatment plant.
