Di-Trimethylolpropane is an organic compound. It is a colorless liquid with low volatility and solubility, stability and antioxidant properties.
Applications
Di-Trimethylolpropane has a wide range of applications in the chemical industry. It can be used as a cross-linking agent for adhesives, resins and coatings, and can improve their abrasion, heat and chemical resistance. In addition, it is used in the preparation of synthetic materials such as polyurea, polyurethane and polyester.
Precautions
The common method of preparing Di-Trimethylolpropane is to synthesize it by performing a condensation reaction of formaldehyde with propylene glycol. The reaction requires the addition of a base catalyst and control of the reaction temperature and reaction time.
It is a flammable liquid and will burn when exposed to open flames or high temperatures and should be kept away from sources of ignition. Store it sealed and away from oxidizers and acids. When operating, wear protective glasses and gloves to avoid direct contact with skin and eyes. In case of accidental contact, flush immediately with plenty of water and seek medical attention.
