Beta Naphthol product image
Beta Naphthol is a white to red plate-like crystal that darkens in color when stored in air for a long time. It is commonly used in the manufacture of tartaric acid, butyric acid, β – naphthol-3-carboxylic acid, and azo dyes. It is also a raw material for rubber anti-aging agents, mineral processing agents, fungicides, mold inhibitors, preservatives, parasitic control and deworming drugs.
Beta Naphthol has chemical properties similar to phenol, and can also undergo electrophilic substitution of aromatic rings and reactions with phenolic hydroxyl groups. Naphthol is different from phenol in that its hydroxyl group can be replaced by an amino group to form naphthylamine. Naphthol can undergo coupling reaction with diazonium salts, which is the basis for producing azo dyes. 2-Naphthol undergoes coupling at the alpha position, and the resulting product can react with sodium hydroxide due to intramolecular hydrogen bonding.
Beta Naphthol shipping picturesWhen shipping 2-naphthol, a dangerous goods vehicle is required for transportation. Because it is a Class 9 hazardous material, it poses a potential threat to water sources and marine life. Its UN number is 3077. Dangerous goods labels should be affixed to its outer packaging for people to identify. When storing 2-naphthol, it is necessary to use a hazardous material warehouse.
Beta Naphthol Analysis Specification
The most important indicator in the analysis report of 2-naphthol is its content. In today’s industry, the content of 2-naphthol is generally greater than or equal to 99%. Some manufacturers have already achieved a content of 99.4%, becoming the main force in exports.
Beta Naphthol Manufacturer
Manufacturers of 2-naphthol generally require the use of raw material refined naphthalene. Some manufacturers obtain it through procurement, while others produce refined naphthalene themselves.
Package
Beta Naphthol is usually packaged in a 25kg plastic woven bag lined with a layer of PP. This is both sturdy and affordable.
