18655-47-5 - Introduction
Triformylmethane, chemical formula (C3H3O)2CH2, also known as propenone dimer, is an organic compound. The following is a detailed description of the nature, use, formulation and safety information of Triformylmethane:
Nature:
Triformylmethane is a colorless to light yellow liquid with a pungent odor. It is insoluble in water at normal temperature, but soluble in organic solvents such as alcohols, ethers, ketones and aromatic hydrocarbons. It has a low density and a boiling point of about 70-80 degrees Celsius.
Use:
Triformylmethane is widely used in chemical synthesis and organic reagents. It can be used as a solvent in catalysts, stabilizers and reagents. In addition, in the field of pigments, dyes and coatings, it is also used for synthesis and modification.
Method:
Triformylmethane can be polymerized by the reaction of propylene ketone itself or dicyandiamide. Here, the self-polymerization means that the propylene ketone is subjected to thermal polymerization in the presence of a catalyst. The dicyandiamide reaction is the condensation of propylene ketone and dicyandiamide under the action of alkali catalyst.
Safety Information:
Triformylmethane is irritating and should be avoided in contact with skin and eyes. Wear protective gloves, goggles and protective clothing when using. At the same time, to maintain good ventilation, avoid inhalation of its steam. Because it is flammable, it should be kept away from fire and high temperature, and stored in a sealed container.
