    Abstract: Disclosed is a method for producing benzophenones of formula I, wherein X can represent chlorine, hydroxy, methoxy, or C1-C6 alkylcarbonyloxy while Y represents chlorine or bromine, by reacting an acid chloride of formula II, wherein X and Y have the meaning mentioned above, with 3,4,5-trimethoxytoluene. The inventive method is characterized by the fact that the reaction is carried out in the presence of a) an aromatic hydrocarbon as a thinner, and b) 0.01 to 0.2 mole percent of an iron catalyst, the percentage being in relation to the acid chloride, c) at a temperature ranging between 60oC and the boiling point of the respective thinner.

    Abstract: The invention relates to a method for producing 5-halo-2,4,6-tifluoroisophthalic acid of formula (I), wherein X represents F, Cl, Br, or I, by hydrolysis of 5-halo-2,4,6-trifluoroisophthalodinitrile of formula (II). Said invention is characterised in that in a first step, isophthalodinitrile (II) or a solution containing isophthalodinitrile (II) is reacted with a concentrated sulphuric acid at room temperature in order to form a 5-halo-2,4,6-trifluoroisophthalodiamide of general formula (III), and is, subsequently, heated and in a second step, isophthalic acid (I) is produced after additional heating and addition of water.

    Abstract: A process for preparing 2-{1-[2-(4-chlorophenoxy)propoxyimino]-butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)cyclohex-2-enone lithium salt by reacting the corresponding acid 2-{1-[2-(4-chlorophenoxy)-propoxyimino]butyl}-3-hydroxy-5-(tetrahydrothiopyran-3-yl)-cyclohex-2-enone and lithium hydroxide and the isolation of the lithium salt are described. Here, it is advantageous to use a solvent mixture which comprises methanol and at least one aromatic hydrocarbon and to remove at least some of the solvent prior to the isolation. It is particularly preferred to dissolve the acid in an aromatic hydrocarbon, preferably toluene, and to use a methanolic lithium hydroxide solution. The product, which can be obtained in a more efficient manner by this process, furthermore has considerable advantages with respect to formulation.
