ethanaminium bromide - Introduction
methylammonium bromide is an organic compound with the chemical formula CH3NH3Br, commonly abbreviated as MABr. The following is a description of the nature, use, formulation and safety information of methylammonium bromide:
Nature:
-Appearance: colorless crystal or white powder
-Solubility: Soluble in water and organic solvents
-Melting point: About 185-190 ° C
-Density: about 1.6g/cm³
Use:
-Photovoltaic materials: methylammonium bromide is commonly used in organic perovskite solar cells as a calcium source and stabilizer for perovskite materials.
-Chemical reaction: methylammonium bromide can be used as a precursor of quaternary ammonium salt derivatives for organic synthesis reactions.
-Ionic liquid: methylammonium bromide can also be used to prepare ionic liquids with specific functions.
Method:
The preparation of methylammonium bromide is usually carried out by the following steps:
1. Methylamine (CH3NH2) reacts with hydrogen bromide (HBr) to generate methylamine hydrochloride (CH3NH3Cl).
2. Methylamine hydrochloride is reacted with sodium bromide (NaBr) to give methylamine sodium bromide (CH3NH2Br).
3. Methylamine sodium bromide reacts with hydrochloric acid (HCl) to give the final product methylammonium bromide(CH3NH3Br).
Safety Information:
methylammonium bromide is an organic compound that is easy to prepare. However, due to its odor and irritation to eyes, respiratory tract and skin, appropriate safety precautions should be taken during use, such as wearing chemical safety glasses, protective gloves and respiratory protection equipment. At the same time, during storage and handling, avoid contact with open flames and other flammable substances, and store in a dry and well-ventilated place.
