Introduction
Phthalate (also known as ortho-dimethoxybenzene, or ODM for short) is a colorless liquid. The following is an introduction to the nature, use, manufacturing method and safety information of ODM:
It is highly volatile at room temperature and can be dissolved in a variety of organic solvents.
Usage: ODM has a wide range of applications in many fields. It can also be used to make dyes, plastics, synthetic resins, and other chemicals.
Preparation method: The preparation of ODM can be carried out by phthalate etherification reaction. Under the action of an acid catalyst, phthalic acid reacts with methanol to form methyl phthalate. Then, methyl phthalate is reacted with methanol with an alkali catalyst to generate ODM.
Safety information: ODM has a certain toxicity, and safety should be paid attention to when using and handling ODM. It is a flammable liquid and should be avoided from contact with fire sources. Also avoid inhalation, contact with skin and eyes. When using ODM, appropriate personal protective measures such as wearing protective glasses and gloves should be taken, and ensuring that it is used in a well-ventilated environment.
