双酚A 是聚碳酸酯、聚砜和环氧树脂等工程塑料的主要单体,又是有机合成工业中用途广泛的原料之一。它由丙酮和苯酚在酸性催化剂的影响下,缩合反应而得:在缩合反应动力学研究方面和在生产控制中常常需要快速、同时测定反应液和酚-水洗涤液中苯酚和双酚A 的含量。本文通过对苯酚和双酚A 紫外吸收光谱曲线的研究和它们易溶于醇的特性,提出在醇-水混合溶液中,用紫外分光光度分析法,快速、同时测定苯酚、双酚A混合物和酚水洗涤精制双酚A 过程中产生的废液中
Bisphenol A is the main monomer of engineering plastics such as polycarbonate, polysulfone and epoxy resin, and is also one of the raw materials used extensively in organic synthesis industry. It is derived from the condensation reaction of acetone and phenol under the influence of acidic catalysts: it is often necessary to rapidly and rapidly determine the kinetics of condensation reactions and the simultaneous determination of phenol and bisphenol A in the reaction and phenol-water washings content. In this paper, the phenol and bisphenol A UV absorption spectra of the curve and their characteristics of alcohol-soluble, proposed in the alcohol - water mixed solution, UV spectrophotometry, rapid and simultaneous determination of phenol, bisphenol A mixture and Phenol water was used to wash the waste produced during the purification of BPA
