摘要： The disposal of chlorinated pitches is carried out by means of a process which consists of two treatments with an alkanol, which are carried out in cascade.
Such treatments cause the precipitation to take place of the suspended matter, which is then caused to settle, is separated and is pyrolized, whilst the supernatant is distilled in order to separate the alkanol, which is recycled back to the process, and the other organic components, which are sent to further uses.

摘要： The present invention relates to a process for the purification of raw acetone deriving from processes for the production of phenol acetone, impurity mainly due to cumene, water, aldehydes and methanol, which comprises:

feeding the stream of raw acetone coming from the primary fractionation of a plant for the production of phenol/acetone to a first distillation column to which a solution of sodium hydroxide at 2% is also fed;
sending the stream at the head of the first column, consisting of acetone, water and cumene to a second column to which the extractive solvent triethyleneglycol is also fed;
recovering the practically anhydrous acetone from the head of the second column;
feeding the bottom product of the second column, containing triethyleneglycol, water, cumene and acetone to a third distillation column in which an azeotropic mixture of water/cumene is recovered from the head and anhydrous triethyleneglycol from the tail;
sending the azeotropic mixture of water/cumene to a decanter in which a water phase is separated, containing acetone, which is recycled to the first column and an organic phase, containing cumene and acetone, which is sent to the primary fractionation.
摘要翻译：本发明涉及一种用于生产丙酮丙酮衍生物的原料丙烷的纯化方法，主要是由于异丙基苯，水，醛和甲醇引起的杂质，该方法包括：将来自主分馏用于将苯酚/丙酮生产到第二蒸馏塔的设备，其中还加入氢氧化钠溶液2％的溶液; 将由丙酮，水和异丙基苯组成的第一列的头部的料流送至萃取溶剂三乙二醇也供给的第二塔; 从第二塔的头部回收几乎无水的丙酮; 将含有三乙二醇，水，异丙基苯和丙酮的第二塔的底部产物进料到第三蒸馏塔中，其中从头部回收水/枯烯的共沸混合物和来自尾部的无水三乙二醇; 将水/异丙基苯的共沸混合物送入其中分离水相的含水丙酮的滗析器，该丙酮循环至第一塔，并含有含有异丙基苯和丙酮的有机相，送入初级分馏。
