查询词典 dwell

A method for making Bisphenol A with a purity of more than 99.7% by reacting phenol and acetone using an acid catalyst, separating a BPA-phenol adduct by crystallisation and removing phenol from the adduct, in which involves continuous suspension crystallisation with a total dwell time of more than 4 hours in at least 3 crystallisers, by cooling first to 50-70 C in two parallel crystallisers and then to 40-50 C in a third crystalliser connected in series with the first two.; A method for the production of Bisphenol A with a purity of more than 99.7%, by reacting phenol with acetone in presence of an acid catalyst, separating a BPA-phenol adduct from the product mixture by crystallisation, filtration and washing, and removing the phenol from the adduct, in which stage involves continuous suspension crystallisation in at least three crystallisers connected in such a way that the mixture is first cooled to 50-70 C in two crystallisers in parallel and then cooled to 40-50 C in a third crystalliser in series with the first two, the total residence time of the mixture over all crystallisers being more than 4 hours.

描述用于生产纯度大于99.7％的双酚例如，双酚A(BPA的方法，这种方法包含苯酚和丙酮在有酸性催化剂参与的情况下反应形成一个包含双酚的产物混合物；通过结晶、过滤和洗涤从该产物混合物中以双酚/苯酚复合物的形式除去至少一部分双酚以提供双酚A/苯酚复合物晶体；并且从双酚/苯酚复合物晶体中除去至少一部分的苯酚以提供纯度大于99.7％的双酚；其中结晶过程包括连续的混悬液结晶，并且是在至少三个结晶装置中进行的，装置的排列使得产物混合物首先在结晶过程的第一阶段在第一个结晶装置和并联的第二个结晶装置中被冷却到50至70℃的温度，随后在结晶过程的第二阶段在与第一和第二个结晶装置下游串联的第三个结晶装置中被冷却到40至50℃的温度，并且其中产物混合物在结晶过程中的总驻留时间在4小时以上。
