Definitions

  • the present invention relates to a process for producing bisphenol A, a raw material for producing plastics, in particular polycarbonates.
  • Bisphenol A 2,2-bis-(4-hydroxyphenyl)propane, named also the p,p'-BPA isomer
  • BPA Bisphenol A
  • p,p'-BPA isomer is used for producing plastics, in particular polycarbonates, their blends and epoxy resins, as well as, but in minor quantities, for producing phenoplasts, unsaturated polyester resins, polysulfones, polyetherimide and polyacrylic resins as well as polyuretanes and additions for plastics, inter alia fiameretardants, for example tetrabromobisphenol A and phenylphosphates of BPA and thermal stabilizers for polyvinyl chloride.
  • fiameretardants for example tetrabromobisphenol A and phenylphosphates of BPA and thermal stabilizers for polyvinyl chloride.
  • An alternative process for catalyzing the reaction of obtaining BPA is the use of strongly acidic ion-exchange resins (cation exchangers) which met larger and larger approbation, and finally displaced methods using H 2 SO 4 or HCl as catalysts for condensation reactions. It was recommended also the use of sulfonated copolymers of styrene and divinylbenzene (DVB) and sulfonated phenol-formaldehyde resins, the first of the mentioned catalyst types being broadly used at present on an industrial scale. Initially, cation exchangers of considerable cross-linking degree were used, and next, gel cation exchangers of lower cross-linking degree were started to be used (2-4 cg/g ofDVB).
  • promoters which are thioorganic compounds having a thiol group or being capable of its formation in condensation reaction conditions. Numerous tests for using homogeneous promoters were taken up. However, their use caused problems associated with obtaining a product of high quality. For this reason, at present, more and more popular are ion-exchange resins modified with thioorganic compounds in such a manner which provides their attachment with a sulfonic group, and to this end amine groups or heterocyclic compounds comprising nitrogen atom(s) of basic character are used mostly.
  • One embodiment used for a synthesis unit includes a multi-stage system of flow reactors with a fixed-bed catalyst, connected in series through heat exchangers which enable to maintain an assumed temperature range in successive reactors, individual embodiments differing each other in supplying acetone and post-crystallization liquors resulted from successive stages of the BPA isolation and purification, hi the case of such embodiments for a reaction system, are known and described inter alia in the US-Patent 6414199 advantages resulting from dividing the stream of acetone to be supplied into reactors connected in series, which advantages consist, first of all, in increasing the catalyst lifetime and selectivity of a condensation reaction, which results from a better temperature distribution in the catalyst bed as well as from more possibilities of controlling the course of a BPA synthesis reaction.
  • Advantages are known which result from recycling post-crystallization liquors, and in the case of recycling to the crystallization stage or concentration stage before crystallization the advantage consists in recycling a non-reacted phenol and a non-crystallized BPA which decreases significantly a raw material consumption.
  • An additional advantage resulting from recycling the mother liquor to the synthesis stage consists in a limitation of formation of 2-(2- hydroxyphenyl)-2-(4-hydroxyphenyl)propane (so called o,p'-BPA isomer) as then the system approximates more closely the state of equilibrium of the p,p'-BPA and o,p'-BPA isomers.
  • Recycling the mother liquor does not solve fully the problem of byproducts as they are cumulated, and one method for solving this problem lies in discharging a part of the post-reaction stream from the process with the aim to maintain their concentration at an acceptable level. Even, when phenol is distilled from this stream, so this indispensable process affects undesirably economical factors of the process for producing BPA.
  • a process of catalytic decomposition of by-products is considered in the patent literature as an introduction to the process of a BPA synthesis from products of this decomposition, carried out most frequently in the presence of macroporous ion-exchange resins as catalysts.
  • the isomerization reaction allows to convert o,p'-BPA into p,p'-BPA as well as, according to some reports, also trisphenols, first of all, 2,4-bis-[2-(4-hydroxyphenyi)- isopropyl]phenol (JP 08333290) appearing among them in most considerable quantities.
  • JP 08333290 2,4-bis-[2-(4-hydroxyphenyi)- isopropyl]phenol
  • a purpose of the invention was the development of a process for producing bisphenol A of clear and stable colour in a liquid state, which is characterized by good efficiency and selectivity. It has been found unexpectedly that recycling a mother liquor to the last synthesis stage, as compared with a variant in which its recycling to the reactor of the first stage, allows both to limit the number of by-products other than the o,p'-
  • Li a process in which advantages of recycling the mother liquid to the third stage of condensation reaction are used up, and in the case of using the fractionation of products from catalytic decomposition and recycling only phenol to the process, the indices of a raw material consumption are not satisfying in view of the fact that the o,p'-BPA isomer, which is formed in such a technological variant in considerable quantities, forms in conditions of catalytic decomposition a considerable amount of isopropenylphenols and their oligomers which are discharged from the process.
  • the process for producing bisphenol A according to the invention uses the isomerization of o,p'-BPA into p,p'-BPA and recycling the isomerizate to crystallization, as well as a catalytic decomposition of the stream of post-crystallization liquors and fractioning the decomposition products, and next recycling to the process phenol only resulting from the decomposition process. It allows to avoid problems associated with the new kinds of by-products, and at the same time to ensure high indices of the conversion of a raw material into bisphenol A.
  • the essence of the process of the invention consists in the fact that the condensation reaction of acetone and phenol is carried out in a multi-stage reaction system with an interstage control of the reaction temperature and acetone concentration as well as a control of water concentration before the last stage of the reaction system by recycling a part of post-crystallization liquors from a solvent crystallization to the stream directed to the last reactor, while metering in a continuous manner to the system of reactors containing a catalyst the reaction mixture comprising acetone and phenol.

Abstract

La présente invention concerne la production de bisphénol A à partir de phénol et d'acétone au moyen d'une condensation catalytique effectuée en présence de résines échangeuses d'ions sulfonatées activées, par cristallisation fractionnelle pour isoler l'isomère p,p'-BPA. La réaction de condensation de l'acétone et du phénol est réalisée dans un système réactionnel à étapes multiples avec un contrôle entre les étapes de la température de la réaction et de la concentration d'acétone ainsi que le contrôle de la concentration en eau avant la dernière étape du système réactionnel. Une partie des liqueurs de post-cristallisation issues des cristallisations dans des solvants est recyclée vers le dernier réacteur. L'eau et l'acétone sont évaporées du mélange post-réactionnel qui est ensuite mélangé avec la solution effluente issue de la cristallisation fractionnelle dissoute dans l'isomérat obtenu par le procédé d'isomérisation d'une partie du courant des liqueurs concentrées après cristallisation dans des solvants. Le courant résultant est soumis à une cristallisation dans un solvant, le produit d'addition bisphénol A/phénol isolé est soumis à une décomposition thermique, et le bisphénol A brut résultant est soumis à une cristallisation fonctionnelle.
