4-Methoxyphenol

What Is 4-methoxyphenol?

4-Methoxyphenol, also known as p-methoxyphenol, p-hydroxyanisole, etc., is a chemical substance with a chemical formula of C7H8O2. It appears as white flakes or waxy crystals, easily soluble in ethanol, ether, acetone, benzene and ethyl acetate, and slightly soluble in water. It is mainly used as an inhibitor for vinyl plastic monomers, an ultraviolet inhibitor, a dye intermediate, and for the synthesis of edible oils and cosmetic antioxidants such as BHA. Its biggest advantage is that the monomer after adding MEHQ does not need to be removed when copolymerizing with other monomers, and can be directly copolymerized by ternary polymerization. It can also be used as an antioxidant, antioxidant, etc. It is not only an important fine chemical product, but also an important intermediate for the synthesis of fine chemical products such as medicines, pesticides, and spices.

Characteristics And Properties

• Slightly soluble in water, easily soluble in organic solvents such as ethanol, ether, acetone, benzene and ethyl acetate.
• Stable at room temperature and pressure, but avoid contact with prohibited substances such as alkalis, acyl chlorides, acid anhydrides, oxidants, etc.
• It can be used as an inhibitor for vinyl plastic monomers, such as styrene, acrylates, acrylonitrile, etc. It is effective at low temperatures and will decompose and lose its inhibitory effect at high temperatures.
• It is an important raw material for synthesizing the antioxidant BHA, which can be used in edible oils and cosmetics to prevent oils from oxidizing and deteriorating.
• It has ultraviolet inhibition function and can be used in related fields to protect materials from ultraviolet damage.

Uses

Food

Due to its excellent antioxidant properties, it is widely used as a food preservative to extend the shelf life of food. It can be used to add spices to enhance the flavor of food.

Cosmetics

In cosmetics, it can effectively inhibit bacterial growth and maintain product stability.

Its antioxidant properties help protect the skin from free radical damage.

Medicine

As an antibacterial agent and preservative, it effectively inhibits the growth of a variety of bacteria and fungi.

Used in the manufacture of topical ointments and disinfectants.

Plastics and dyes

Used as an inhibitor, UV inhibitor, and dye intermediate for vinyl plastic monomers.

Antioxidant BHA used in the synthesis of edible oils and cosmetics.

Production Method

(1) Dimethyl sulfate method: dimethyl sulfate is used as a methylating agent and reacted with hydroquinone under alkaline conditions to obtain the product. The reaction formula is as follows:

(2) Methanol method: hydroquinone reacts with methanol under the action of a catalyst to obtain the product. The reaction formula is as follows:

(3) p-Anisidine is used as a raw material. Under the action of mixed acid, p-Hydroxyanisole is obtained by two-step reactions of diazotization and hydrolysis. The reaction formula is as follows:

This process has the advantages of low raw material cost, simple operation, and easy industrialization, making the production of this product highly competitive in the market. Based on p-Anisidine, the synthesis yield reached 76.8% and the purity reached more than 99.5%.
