trimethylammonium acetate buffer - Introduction
trimethylammonium acetate buffer is a commonly used buffer that can maintain the stability of the solution under acidic and alkaline conditions. The following is an introduction to the nature, use, method and safety information of trimethylammonium acetate buffer:
Nature:
-Appearance: generally white crystal or crystalline powder;
-Solubility: soluble in water, methanol and ethanol, insoluble in ether solvents;
- pH range: At 25°C, the pH range is 3-8.
Use:
-Buffer: trimethylammonium acetate buffer can be used as a buffer in chemical and biological laboratories to help maintain a stable pH value of the solution;
-Solvent: Due to its good solubility, it can be used as a solvent for catalysts or reaction intermediates;
-Technical application: It can be used in organic synthesis reactions and catalytic reactions to improve yield and selectivity.
Preparation Method:
trimethylammonium acetate buffer can be prepared by the reaction of trimethylamine and acetic acid. The specific preparation method is as follows:
Dissolve an appropriate amount of trimethylamine in water, and then add acetic acid dropwise to the trimethylamine solution at an appropriate rate while stirring. Finally, the trimethylammonium acetate buffer was obtained by filtration and crystallization.
Safety Information:
- trimethylammonium acetate buffer is a low-toxic substance, it still needs to follow the routine laboratory safety procedures;
-Use personal protective equipment such as lab gloves and safety glasses when exposed;
-Avoid inhaling the gas of powder or solution, and try to operate in a well-ventilated place;
-If swallowed or in contact with skin, seek immediate medical attention.
