Product Description of Mequinol powder
 It can be prepared by using hydroquinone as raw material, dimethyl sulfate as methylating agent, or methanol as methylating agent under high temperature and pressure and catalysis 4-methoxyphenol. Another newer method is the reaction of hydroquinone with methanol in the presence of p-benzoquinone. Mix methanol with concentrated sulfuric acid The mixture is homogeneous, hydroquinone is added, and the mixture is heated to reflux, and a methanol solution of p-benzoquinone is added dropwise to react for 3 hours. Cool and neutralize with 40% sodium hydroxide solution,The sodium sulfate precipitate was filtered off.
After the methanol was recovered from the filtrate, the mixture was extracted with ether, and the ether was distilled off from the extract, followed by distillation under reduced pressure.The finished product was obtained at a distillate of 112 ° C (0.53kPa). The yield was 76% 
Function of Mequinol powder
1. Used as a polymerization inhibitor, ultraviolet inhibitor, dye intermediate for vinyl-based plastic monomers and as an antioxidant for the synthesis of edible oils and cosmetics agent BHA (3-tert-butyl-4-hydroxyanisole) and so on.
2. It is an important intermediate for fine chemical products such as medicine, spices, pesticides, etc., and has a wide range of uses. Mainly used in the production of acrylonitrile, acrylic acid and Its ester, methacrylic acid and its alkenyl monomers are polymerization inhibitors. Its biggest advantage is that it does not need to remove p-hydroxyanisole during use, it can directly participate in the aggregation. It is also used in the synthesis of antioxidants, plasticizers and food additives (BHA).

Application of Mequinol

1.Used as Intermediates of Liquid Crystals.

2.Used as a reducing agent, nylon whitener, also used as a raw material phosphate, pesticide intermediates and plasticizers.

3.Used as an inhibitor in binyl and acrylic monomers and stabilizer to inhibit peroxide formation in ethers,chlorinated hydrocabons and ethyl cellulos.
