METHOD FOR PRODUCING BISPHENOL COMPOUND

PROBLEM TO BE SOLVED: To provide a method for producing an aldehyde bisphenol compound, which makes it possible to produce a 4,4'-substituted body with significantly high regioselectivity in an efficient and easy manner. SOLUTION: A production method includes producing a bisphenol compound represented by the formula (1) in a state in which at least phenol, heteropoly acid, and a trioxane compound such as paraldehyde coexist. [In formula (1), R1 is a hydrogen atom or a C1-29 monovalent organic group. R2 and R3 each denote a halogen atom or a C1-29 monovalent organic group. a and b each denote an integer of 0-4].

Preparation method for bisphenol E

A preparation method for bisphenol E is disclosed and belongs to the field of preparation methods for bisphenol compounds. The technical problems that a conventional bisphenol E preparation method is complex in operation, toxicity is high and the finished-product purity is low are solved. The method comprises step 1, precipitating a crystal; step 2, washing and drying, so as to obtain a crude product; and step 3, performing rectification. By employing the method, the usage amount of phenol is reduced, reaction time is shortened, the product ratio in the crude product is improved, and the final product bisphenol E purity is 99.9%. In the method, petroleum ether is employed for replacing cyclohexane, thus the cost is reduced, and petroleum ether and ethyl acetate are employed for replacing toluene as a refined solvent, and thus the toxicity is reduced.

MANUFACTURING METHOD FOR POLYCARBONATE

A method for manufacturing polycarbonate by melt-polycondensing bisphenol and carbonic acid diester uses as catalyst an alkali metal compound and/or alkaline earth metal compound (a). The catalyst is added to the bisphenol prior to the melt polycondensation, in an effective amount, i.e., the amount of alkali metal compound and/or alkaline earth metal compound (a) that acts effectively as a catalyst, is contained in said bisphenol, and is controlled to have the same catalytic activity as 1×10?8 to 1×10?6 mole of bisphenol disodium salt per mole of pure bisphenol A. The method conducts the reaction efficiently from the initial stage in a stable manner to obtain polycarbonate with good color, good heat stability and color stability during molding and the like.
