ລາຍລະອຽດຜະລິດຕະພັນ

ເມທີລເບນຊີນ, an organic compound, is a colorless, volatile liquid with a distinctive aroma. It has strong refraction. It is miscible with ethanol, ອີເທີ, ອາເຊໂທນ, chloroform, carbon disulfide and glacial acetic acid, and very slightly soluble in water. Flammable, vapor can form an explosive mixture with air, and the mixture can explode when the volume concentration is in a low range. Low toxicity, median lethal dose (rats, orally) 5000mg/kg. High concentrations of gas are anesthetic and irritating.

ຄໍາຮ້ອງສະຫມັກ

1. ທາດລະລາຍ: Methylbenzene is an excellent solvent, can dissolve a variety of organic matter. Due to its good solubility and volatility, it is widely used in industrial and household applications such as coatings, inks, glues, cleaners and adhesives.

2. ອຸດສາຫະກໍາເຄມີ: MePh is an important raw material and intermediate for the synthesis of a variety of chemicals. For example, it is a raw material for the synthesis of styrene, which is used to prepare polystyrene (PS) ພາດສະຕິກ; It can also be used to prepare toluene diisocyanate (TDI) for the production of polyurethane foam materials.

3. Dyes and pigments: MePh can be used as a solvent and carrier for dyes and pigments to promote dye dispersion and penetration. It is widely used in the fields of textile, papermaking, printing and painting.

4. Spices and flavors: Because chemical methylbenzene has a unique aromatic smell, it is used as a component of spices and flavors. It can give special smells and fragrances to food, beverages, perfumes and household items.

5. Cleaners and solvents: Toluene has the ability to dissolve in industrial cleaners and solvents, and can remove grease, stains and other attachments. Therefore, it is widely used in automotive maintenance, mechanical cleaning and metal surface treatment and other fields.
