| Detailed Product Description: | High purity phenol chemical reaction ability. With aldehydes, ketones reacted phenolic resin, bisphenol A, and acetic anhydride; the reaction of salicylic acid phenyl acetate, salicylate. How the solubility of phenol? Phenol soluble in ether, chloroform, glycerol, carbon disulfide, petrolatum, volatile oil, alkali solution. Normal temperature soluble in ethanol, glycerol, chloroform, ether and other organic solvents, slightly soluble in water at room temperature, mixed with about 8% of water can be liquefied phenol printing inks, more than 65 ℃ miscible with water, almost insoluble in petroleum ether. Phenol: sodium phenol with acetic anhydride reaction. Phenol was added 15% sodium hydroxide solution, and stirred to dissolve the sodium phenol solution formulated as phenol, acetic anhydride was added and reacted at 30-40 ℃. The resulting reaction product was washed with water, 5% sodium hydroxide solution, washed with water, dried calcium chloride drying, distillation derived products. Reaction time required for this method is very short, the yield of about 77%. Another method of operation is to phenol and acetic anhydride are heated together to boiling phenol preservative, at reflux for 3h, successively washed with water, caustic washing, cleaning phenol price after cooling, dried over anhydrous sodium sulfate, and distilled to collect 190-195 ℃ fraction, Good for phenyl acetate. The yield of about 83%. Rubber phenol, phenol, Wei Wei Connaught Chemical provided by Qingdao Sino Chemical Co. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) strong, credible, in Qingdao, Shandong and other chemical products industry has accumulated a large number of loyal customers.
