What is 4-Methoxyphenol?
4-Methoxyphenol is a chemical substance with the appearance of white flakes or waxy crystals. Its molecular formula is C7H8O2. It is used as an inhibitor for vinyl plastic monomers, a UV inhibitor, a dye intermediate, and an antioxidant BHA (3-tert-butyl-4-hydroxyanisole) for the synthesis of edible oils and cosmetics. It is an important intermediate for fine chemical products such as medicines, spices, and pesticides. It is mainly used as an inhibitor for the production of vinyl monomers such as acrylonitrile, acrylic acid and its esters, and methacrylic acid and its esters. Its biggest advantage is that p-hydroxyanisole does not need to be removed when used, and it can directly participate in polymerization. It is also used in the synthesis of antioxidants, plasticizers, and food additives (BHA).
Properties and stability
1. Stable at room temperature and pressure.
2. Prohibited substances: alkalis, acyl chlorides, acid anhydrides, oxidants.
3. Exists in flue-cured tobacco leaves, oriental tobacco leaves, and smoke.
Main uses
1. Used as an inhibitor for vinyl plastic monomers, UV inhibitors, dye intermediates, and antioxidant BHA (3-tert-butyl-4-hydroxyanisole) for the synthesis of edible oils and cosmetics.
2. It is an important intermediate for fine chemical products such as medicines, spices, pesticides, etc., and has a wide range of uses. It is mainly used as an inhibitor for the production of vinyl monomers such as acrylonitrile, acrylic acid and its esters, methacrylic acid and its esters. Its biggest advantage is that when used, it is not necessary to remove p-hydroxyanisole, and it can directly participate in polymerization. It is also used as an antioxidant, plasticizer, and food additive (BHA) synthesis.
Production method
4-Methoxyphenol can be obtained by using hydroquinone as raw material and dimethyl sulfate as methylating agent, or by using methanol as methylating agent under high temperature, high pressure and catalysis. Another newer method is to react hydroquinone with methanol in the presence of p-benzoquinone. Mix methanol and concentrated sulfuric acid evenly, add hydroquinone, heat to reflux, and drop a methanol solution of p-benzoquinone to react for 3 hours. Cool, neutralize with 40% sodium hydroxide solution, filter out sodium sulfate precipitate. Recover methanol from the filtrate and extract with ether. Distill the extract to remove ether, then perform vacuum distillation, collect the fraction at 110-112℃ (0.53kPa) to obtain the finished product. The yield is 76%.
