| PURPOSE: To obtain a mixture suitable for a well bore fluid by producing by a two-step process comprising a first step to form a penta-bromo-derivative from an aromatic compound and bromine and a second step to form a tribromo- derivative or a mixture of di- and tri-bromo-derivatives from an additional amount of the aromatic compound and bromine in the presence of the penta- bromo-derivative. CONSTITUTION: The process comprises two steps; (a) at first reacting an aromatic compound with brcrmine in a molar ratio of bromine to the aromatic compound from 30:1 to 5:1 in the presence of a brominating catalyst to convert the compound substantially to a penta-bromo-derivative and (b) subsequently reacting, in the presence of the reaction product of the preceding step (a), an additional amount of the aromatic compound, the ratio thereof to the initial amount ranging front 100:1 to 0.1:1, with an additional amount of bromine in a molar ratio of bromnine to the aromatic compound from 10:1 to 1:1 in the presence of the brominating catalyst for a sufficient time to give a tri- bromo-derivative or a mixture composed of di-bromo- and predominant tri- bromo-derivatives, which product is substantially free form a tetra-bromo derivative and can be used as a well bore fluid without a toxicological problem.

| 123 | Removing method for minor sulfur compound contained in aromatic compound such as benzene or the like | JP13301686 | 1986-06-09 | JPS62289532A | 1987-12-16 | TODA MINORU; TAO KATSUTOSHI; TAKEDA MOTONORI; SUEOKA SADAAKI; MAKISHIMA HIROKI |
| PURPOSE: To obtain an aromatic compound, e.g. benzene, etc., without containing sulfur compounds inhibiting hydrogenation and reductive reaction by a noble metal catalyst, by oxidatively decomposing minor amount of sulfur compounds contained in the aromatic compound with ozone and washing and removing the sulfur compounds with an aqueous alkali. CONSTITUTION: A minor amount of sulfur compounds, particularly thiophene derivatives contained in an aromatic compound, e.g. benzene, etc., is brought into contact with ozone in an amount of 30W100 times based on the above-mentioned sulfur compounds at room temperature or below if the melting point of the aromatic compound is room temperature or below and a somewhat higher temperature than the melting point if the melting point is room temperature or above, selectively and oxidatively decomposed into water-soluble compounds, which are then washed and removed with an aqueous alkali in ≥1% alkali concentration, preferably 2W5% concentration to afford the aimed aromatic compound without containing the sulfur compounds exhibiting catalytic poisoning property, particularly in hydrogenation and reduction after nitration and therefore useful for synthesizing aromatic hydrazo compounds or aromatic amino compounds.

| PURPOSE: To obtain the titled compound easily, by using benzonitrile as a solvent, and reacting a chlorinated cyclic hydrocarbon with a fluorinating agent under spontaneously occurring pressure in a specific temperature range to exchange the halogens. CONSTITUTION: A chlorinated cyclic hydrocarbon [chlorinated benzene shown by the formula I (n is 1W5; m is 0W4, and n+m is ≤6) or chlorinated naphthalene shown by the formula II(p and p' are 0W4; q and q' are 0W3, p+p' is ≤1W≤8, p+q is ≤4, and p'+q' is ≤4) is reacted with a fluorinating agent] preferably one obtained by adding ≤0.3mol cesium fluoride to 1mol potassium fluoride) in a benzonitrile medium at 300W400°C, preferably at 330W380°C under spontaneously occurring pressure to give a fluorinated cyclic hydrocarbon (e.g., fluorobenzene, 1-fluoronaphthalene, etc.). The addition of a phase transfer catalyst to a reaction system can preferably shorten the reaction time. COPYRIGHT: (C)1986,JPO&Japio | ||||||

| PURPOSE: To prepare an organic halogen compound useful as a raw material of fine chemicals, especially a raw material for the syntheses of medicines, efficiently by the halogenation of an easily available hexacoordinate Si compound. CONSTITUTION: Organic halides are prepared by halogenating Si compounds of K 2 [RSiF 5] (R is substituted or unsubstituted monovalent hydrocarbon residue), e.g. K 2[n-C 8H 17SiF 5]. K 2[n-C 12H 25SiF 5], etc., at -30 -100°C in the presence or absence of a solvent, using halogen, such as C1 or Br, or a hlogenating agent such as N- bromosuccinic imide. The molar ratio of the halogen, etc. to the Si compound is 1 2 to 1. COPYRIGHT: (C)1979,JPO&Japio | ||||||
