Description

Overview of Mono-Methyl Terephthalate

Monomethyl terephthalate is a common organic compound with the chemical formula C9H8O4.It is a product obtained by the reaction of terephthalic acid and methanol.It is a colorless liquid with low volatility at room temperature. It is irritating and requires operation in a ventilated area. This compound is widely used as an intermediate in the production of polyester fibers, films, plastics, plasticizers, adhesives and pesticides. Monomethyl terephthalate may be irritating to the skin, eyes and mucous membranes with prolonged or repeated exposure. In addition, monomethyl terephthalate may produce dimers during production, which are harmful to humans and may cause central nervous system toxicity, reproductive toxicity, and developmental toxicity.

Application of Mono-Methyl Terephthalate

Synthetic polyester resin:

Monomethylterephthalate is one of the essential raw materials for synthesizing polyester resins. Reacting with epoxy compounds such as caprolactam, high molecular weight polyester resins can be prepared to manufacture various plastics, fibers, and coatings. This polyester resin has excellent physical properties and chemical stability and is widely used in packaging materials, electrical accessories, automotive parts and other fields.

Solvent:

Monomethyl terephthalate can be used as a solvent, and due to its low volatility and good solubility, it can be used as a solvent component in products such as paint, ink, and glue, making these products more accessible. At the same time, it can also be used as an ingredient in spices and detergents, giving the product a unique odor and cleaning effect.

Plasticizers:

Monomethyl terephthalate is an important plasticizer raw material in the plastic industry. Due to its good solubility and plasticity, it is widely used as a plasticizer for polyester resins. This plasticizer can improve the flexibility and elasticity of polyester resin, making it more suitable for manufacturing various plastic products, such as soft PVC pipes, wire and cable sheaths, plastic films, etc. With the continuous development and growth of the plastic industry, the demand for Monomethylterephthalate is also increasing, so its application prospects in the plastic industry are extensive.

Q:What is the method of preparation of monomethyl terephthalate?
A:Esterification: Terephthalic acid is esterified with methanol in the presence of an acidic catalyst (e.g. sulphuric acid or p-toluenesulphonic acid). Esterification: Dimethyl terephthalate undergoes an esterification reaction with methanol to produce monomethyl terephthalate and methanol.
Q:How safe and environmentally friendly is monomethyl terephthalate?
A:Monomethyl terephthalate solution is neutral or weakly acidic and may cause slight irritation or discomfort on contact with skin and eyes. Protective gloves and goggles should be worn during use. Inhalation of monomethyl terephthalate dust or vapour may cause respiratory discomfort. Good ventilation should be maintained during handling. Accidental ingestion of monomethyl terephthalate may cause gastrointestinal irritation or poisoning. If accidentally swallowed, seek immediate medical attention. Discharge of monomethyl terephthalate solution into the environment may affect aquatic ecosystems. Therefore, waste water after use should be properly treated to ensure compliance with environmental standards before discharge. Waste solid or solution of monomethyl terephthalate should be disposed of in accordance with hazardous waste disposal regulations to avoid pollution of the environment.
