2,5 - Di - tert - butylhydroquinone (DTBHQ) with CAS number 88 - 58 - 4 is a high - quality chemical compound. It appears as a white to off - white crystalline powder. The molecular formula of DTBHQ is C₁₄H₂₂O₂, and its molecular weight is approximately 222.32 g/mol. It has a melting point in the range of 216 - 218 °C. DTBHQ is sparingly soluble in water but soluble in organic solvents such as ethanol, acetone, and benzene.
This product is sourced from high - quality raw materials and is produced under strict quality control measures to ensure its high purity and stability. The purity of our DTBHQ is typically above 99%, which makes it suitable for a wide range of applications.
DTBHQ is widely used in various industries due to its antioxidant properties.
In the rubber industry, it is used as an antioxidant to prevent the rubber from oxidation, aging, and degradation. It can improve the heat resistance and weather resistance of the rubber products, thereby extending their service life. For example, in the production of tires, adding DTBHQ can enhance the durability of the tires under high - temperature and high - stress conditions.
In the plastics industry, DTBHQ can be added to plastic materials to prevent them from yellowing and embrittlement caused by oxidation. It is often used in the production of polyethylene, polypropylene, and other plastic products to maintain their mechanical properties and appearance over time.
It is also used in the food industry as a food antioxidant. It can prevent the oxidation of fats and oils in food, thus extending the shelf - life of food products and maintaining their flavor and quality.
When using DTBHQ, it is recommended to wear appropriate personal protective equipment, such as gloves and goggles.
In the rubber industry, DTBHQ can be added during the rubber mixing process. The recommended dosage is usually in the range of 0.1% - 1.0% based on the weight of the rubber. The exact dosage may vary depending on the type of rubber and the specific requirements of the product.
In the plastics industry, it can be mixed with plastic resins before the molding process. The dosage is typically 0.05% - 0.5% of the plastic resin weight. It should be evenly dispersed in the resin to ensure its antioxidant effect.
In the food industry, the usage of DTBHQ is strictly regulated. It should be added in accordance with the relevant food safety standards. The maximum allowable dosage is usually determined by local food regulations.
Case 1: A rubber manufacturing company was experiencing premature aging and cracking of its rubber hoses. After adding 0.5% DTBHQ to the rubber compound during the mixing process, the hoses showed significantly improved heat resistance and weather resistance. The service life of the hoses was extended by more than 50%, which reduced the replacement frequency and saved costs for the company.
Case 2: A plastic product manufacturer was facing the problem of yellowing and embrittlement of its polypropylene products during long - term storage. By incorporating 0.2% DTBHQ into the polypropylene resin, the products maintained their original color and mechanical properties even after one year of storage. This enhanced the market competitiveness of the products.
Case 3: A food processing company was struggling with the oxidation of fats in its fried snacks. After adding DTBHQ in accordance with the food safety standards, the snacks had a longer shelf - life, and their flavor was maintained for a longer time. This led to a decrease in product returns and an increase in customer satisfaction.
