Filed: 1990-03-27
Abstract: PURPOSE:To obtain the title compound in high yield without any problems in the aspects of working environment by Friedel Crafts acylation, haloformylation, nitration and denitrochlorination successively in this order of a fluorobenzene as starting material. CONSTITUTION:A fluorobenzene of formula I (X is F or Cl) is put to Friedel Crafts acylation into a 5-fluoroacetophenone of formula II, which is then put to haloformylation into a compound of formula III. This compound is then nitrated by a nitrating agent into a compound of formula IV, which is then finally reacted with a chlorinating agent to effect denitrochlorination into a compound of formula V. A compound of formula VI where X is Cl in the formula V is converted to an acyl chloride of formula VII, which is then fluorinated into a compound of formula VIII. This compound is then hydrolyzed to obtain the objective fluorobenzoic acid of formula IX. The present method is industrially advantageous, and the present compound is useful as e.g. an intermediate for antifungal agents.

Title: Apparatus and method for treating waste plastic
Inventor: MAEZAWA YUKISHIGE
IPC: C10G1/10
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To recover fuel oils or chemical raw materials from plastics not easily convertible into oils and wastes containing foreign matter, etc., at good efficiency by using an apparatus consisting of a specified pressure vessel, a specified heating means and a specified extracting means. SOLUTION: This apparatus for treating waste plastic comprizing of a pressure vessel 1 for mixing waste plastics containing at least C, H and other elements with water, a heating means 3 for heating the vessel 1 until the water is converted into supercritical water which can function as a solvent for the heat decomposition reaction of the waste plastics, and means 6 and 7 for extracting oils and solid chemical substances from the solvent. Desirably, an oxygen source such as oxygen, air or H2 O2 is mixed with waste plastics and water, Namely, the number of hydrogen bonds and the orientation force which determine the properties of water depend on the temperature. When the temperature is high, the effect of thermal movement preponderates. It can therefore dissolve nonpolar compounds at the critical point or higher and can further dissolve various gases.  Therefore, water can function as a reaction solvent which accelerates the oxidation reaction of organic compounds.
