molecular structure
Trimethylol aminomethane
brief introduction
Trimethylol aminomethane is a white crystalline powder. It is soluble in ethanol and water, slightly soluble in ethyl acetate and benzene, insoluble in ether and carbon tetrachloride, and corrosive to copper and aluminum.
Buffering characteristics
Trimethylol aminomethane is weakly alkaline at 25 ° C, and its PKA is 8.1; According to the buffer theory, the effective buffer range of Tris buffer is pH 7.0 to 9.2. The pH of the aqueous solution of trimethylol aminomethane is about 10.5. Typically, hydrochloric acid is added to adjust the pH to the desired value to obtain a pH buffer. At the same time, attention should be paid to the effect of temperature on the pKa of trimethylol aminomethane.
Usage
Trimethylol aminomethane is an alkaline buffer, which is widely used in acute metabolic and respiratory acidemia. It has a good buffer effect on metabolic acidosis and enzyme activity reaction. Trimethylol aminomethane can also be used as intermediate of fosfomycin, vulcanization accelerator, cosmetics (cream, lotion), mineral oil and paraffin emulsifier.
