What is the boiling point of methyl methacrylate (MMA)?
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.
The boiling point of methyl methacrylate is the temperature at which the liquid phase of the substance changes to a gaseous phase at standard atmospheric pressure. The compound has a boiling point of 101-103°C, which is related to pressure, purity, solvent and other factors. The higher the boiling point, the greater the intermolecular forces and vice versa, which are closely related to the size of the molecule and its own properties.
What is the use of methyl methacrylate (MMA)?
Methyl methacrylate (MMA), also known as methyl isoenoate, is an organic compound with the chemical formula C5H8O2, a colorless liquid, slightly soluble in water, soluble in most organic solvents such as ethanol, mainly used as a monomer for organic glass, but also used in the manufacture of other resins, plastics, coatings, adhesives, lubricants, lubricants, wood and cork infiltrating agents, paper varnish and so on.

Methyl methacrylate can have a strong stimulating and corrosive effect on human skin, eyes, and respiratory mucosa, and there may be other hazards, long-term exposure is easy to jeopardize the health of the organism.
Is methyl methacrylate a hazardous material?
According to the 2015 edition of the Catalog of Dangerous Goods, Methyl Methacrylate is dangerous goods, Methyl Methacrylate belongs to the third category of flammable liquid dangerous goods.
Methyl methacrylate MMA storage precautions: usually commodities with a polymerization inhibitor. Store in cool and ventilated warehouse. Keep away from fire and heat source. Keep away from light. The storage temperature should not exceed 30℃. Methyl methacrylate MMA packaging requires sealing and no contact with air. Methyl methacrylate MMA should be stored separately from oxidizers, acids, alkalis, halogens, etc. Do not mix storage. Methyl methacrylate MMA should not be stored in large quantities or stored for a long time. Use explosion-proof type lighting and ventilation facilities. Prohibit the use of spark-prone mechanical equipment and tools. The storage area should be equipped with leakage emergency treatment equipment and suitable shelter materials.
