(1) Tetrachlorobisphenol A was synthesised from phenol, propanone and chloride by two steps.

(2) Methyl 1 phenyl Propanone was synthesized with benzene and iso butyryl chloride by using anhydrous aluminium trichloride as catalyst.

(3) RESULT The organic residues were detected before the treatment with alcohol and propanone but not detected after the treatment.

(4) Result shows that the organic releasing film basing on propanone dissolved acrylic resin can give aluminum film or aluminum flake with uniform thickness.

(5) RESULT The organic residues were detected before the treatment with alcohol and propanone but not detected after the treatment. CONCLUSION This ...

(6) The proposed method was applied to extracting pure spectra and determining background of a two component system which consists of dichloroethane and propanone , satisfactory results were obtained.

(7) It is a colourless, flammable liquid with a characteristic smell, miscible with water, alcohol, ether, chloroform and most oils. Also called Dimethyl ketone, Methylacetyl, Propanone, Pyroacetic ether.

(8) METHOD AB 8 resin was treated with alcohol and propanone and the extract was detected for the content of the residues of benzene, methylbenzene, xylene and styrene.
