What is the melting point of methyl methacrylate?
Methyl methacrylate has a density of about 0.94 g/mL, a boiling point of 101-103°C, a melting point of -60°C, and a refractive index of 1.406.
methyl methacrylate melting point
The melting point of methyl methacrylate is the temperature required for the substance to change from a solid to a liquid at standard gas pressure. The compound has a melting point of -60°C and is normally a liquid at room temperature, with a solid state existing only at lower temperatures. The melting point of a molecule is usually closely related to the size of the molecule and the forces at work. The higher the melting point, the greater the intermolecular forces, and vice versa.
Is methyl methacrylate (MMA) flammable?
Methyl methacrylate is flammable, with a low fire point, and is prone to ignition and explosion when in contact with an ignition source. It is also easy to decompose and release flammable gases under high temperature, high pressure and alkaline conditions.
What are the safety precautions for methyl methacrylate (MMA)?
Enhanced Protection
Methyl methacrylate is an irritant to the human body, and contact with the skin, etc. can cause uncomfortable symptoms, and inhalation of too much can lead to respiratory problems. Therefore, operators should wear personal protective equipment such as protective clothing and safety glasses to protect the skin and respiratory tract.
Pay attention to ventilation
The operation process should be well ventilated to ensure air circulation and regular air replacement.
Storage
MMA liquid should be stored in a cool, well-ventilated warehouse, away from fire and power sources, and should not be in contact with oxidizing agents, acids, alkalis, food and other substances during storage to avoid fire and accidents.
