Molecular formula : C15H16O2
MW : 228.29
CAS No. :80-05-7
nature : the white needle crystal flake or powder. Combustible. Microstrip phenol odor. Pure melting point 155-158 ° C, 150-152 ° C industrial melting point, boiling point, 250-252 ° C (1.733kPa), the relative density of 1.195 (30/26 ° C), the flash point of 79.4 ° C Soluble ethanol, acetone, ether, benzene and dilute lye, micro-soluble carbon tetrachloride, almost insoluble in water.
Preparation : phenol and acetone in acid medium condensation derived. When sulfuric acid as a catalyst, the acid concentration of 72.5-76.3%, the reaction temperature is about 40 ° C. The reaction stirred cell, can be intermittent production, but also can be arranged for production devices. Via product and, in isolation from the rough resumption of bisphenol A, xylene-water extraction method derived refined products. Sulfate the equipment needed less simple process, but poor product quality and high consumption of raw materials, "waste" more and are only suitable for small and medium batch production. In order to obtain good quality polymerization of bisphenol-A, commonly used in the industrial production of hydrogen chloride gas law is the catalyst. Will phenol and acetone mixed with dry hydrogen chloride as catalyst under pressure in reaction to 50-60 ° C for 8-9 hours, the concentration of hydrogen chloride gas at over 96%. In addition to generating reaction of bisphenol A, but also generated some isomers, or a hydroxy-3 hydroxy-product. These small amounts of impurities does not affect used in the manufacture of epoxy resin. But when used in the manufacture of polycarbonate, it must be refined. Hooke Process is under pressure distillation, extraction and refining crystal to bisphenol A, product cost reductions. The consumption of raw materials fixed : Phenol 940kg / t, acetone 320kg / t, sulfuric acid (98%) 500 kg / t.
purposes : Bisphenol A is a widely used products, a large number for the production of epoxy resin, polycarbonate, polyester resins, polyphenylene ether resin, polysulfone resins. Also can be used as a stabilizer for PVC, plastics antioxidants, UV absorber, agricultural fungicide, rubber antioxidant and so on. Also can be used as paint, ink and the antioxidants, such as plasticizers.
