Methylamine iodide is a chemical substance. The following is an introduction to the properties, uses, preparation methods, and safety information of methyliodide amine.
Nature:
-Methylamine iodide is a white crystalline solid.
-It is stable at room temperature, but may decompose under high temperature and humid conditions.
-It is a crystalline solid that is soluble in water and organic solvents.
Usage:
-Methylamine iodide is mainly used to prepare perovskite solar cell materials, such as methyllead iodide perovskite.
-It is also used as a catalyst and intermediate, playing an important role in organic synthesis.
Method:
-The preparation method of methylamine iodide is mainly obtained through the reaction of methylamine and hydrogen iodide. The specific preparation method can be to dissolve methylamine in an anhydrous organic solvent, then add hydrogen iodide, and the reaction product can be purified by crystallization to obtain methylamine iodide.
Security information:
-Methyl iodide is an irritant substance, and attention should be paid to protecting the eyes, skin, and respiratory tract when using it.
-When using methyl iodide, it should be operated in a well ventilated area to avoid inhalation or contact with substances.
-It should be stored in a dry, ventilated, and away from heat sources, and away from flammable substances.
-Strictly follow laboratory safety operating procedures when handling methyliodide.
