4-Methoxyphenol Usage and Synthesis.

P-hydroxyanisole is a commonly used fine chemical product, mainly used in polymer blocking agents, antioxidants and plasticizers, but also as an important intermediate in the production of pharmaceuticals, spices and pesticides, etc. Its molecular formula is C7H8O2, molecular weight 124.13. It is also used in the synthesis of edible oils and cosmetics antioxidant BHA.

Its molecular formula is C7H8O2 and molecular weight is 124.1372. p-Hydroxyanisole can also be used to synthesize edible oils and cosmetics antioxidant BHA.

P-hydroxyanisole and related products, such as polymerization inhibitor, quick inquiry, antioxidant, etc., can be purchased from Uno Chemical Co.

Uses of 4-Methoxyphenol.

P-hydroxyanisole is an efficient polymerization inhibitor for unsaturated polyester resin, methyl methacrylate, acrylic eye, vinyl acetate, etc.; stabilizer for polyvinyl chloride, polymethacrylic acid and other polymers.

It can also be used as antioxidant and pharmaceutical intermediates, and made into ointment as bleaching agent, decolorant, infrared Z absorber.

It is an important intermediate for fine chemical products such as medicine, spice and pesticide. It can also be used as polymerizer, antioxidant, plasticizer, etc. It has a wide range of uses.

It is mainly used in the production of acrylonitrile, acrylic acid and its esters, methacrylic acid and its esters and other alkenyl monomers such as polymerization inhibitors.

Its biggest advantage is that when it is used, there is no need to remove P-hydroxyanisole, and it can directly participate in polymerization. It is also used as antioxidant, plasticizer and food additives (BHA) and other synthesis.

Solvent.

It is used as a polymerization inhibitor for vinyl-type plastic monomers; UV inhibitor; dye intermediate and antioxidant BHA (3-tert-butyl-4-hydroxyanisole) for synthesizing edible oils and cosmetics.

Its biggest advantage is that the monomer after adding MEHQ and other monomers need not be removed when copolymerization, can be ternary direct copolymerization, can also be used as an antioxidant, antioxidant and so on.

In vitro studies of 4-Methoxyphenol.

Produt Method of 4-Methoxyphenol.

4-Methoxyphenol can be made from hydroquinone using dimethyl sulfate as a methylating agent, or methanol as a methylating agent under high temperature and pressure and catalysis. Another newer method consists of the reaction of hydroquinone with methanol in the presence of p-benzoquinone.

Mix methanol and concentrated sulfuric acid, add hydroquinone, heat to reflux, and react dropwise with a methanolic solution of p-benzoquinone for 3h.

Cooled, neutralized with 40% sodium hydroxide solution and filtered to remove the sodium sulfate precipitate. The filtrate was recovered methanol and extracted with ether, the extract was evaporated off the ether, and then subjected to decompression distillation, and the finished product was obtained by collecting the fraction at 110-112°C (0.53kPa). The yield was 76%.
