    Abstract: A process for producing hydroxydiaryl ethers of the formula ##STR1## wherein R respesents an alkyl group having 1 to 4 carbon atoms or chlorine, n represents 0, 1, 2, 3 or 4, and X represents a phenyl group of the formula II ##STR2## or a 2-pyridinyl group or a 4-pyridinyl group of the formulae ##STR3## wherein R.sub.1, R.sub.2 and R.sub.3 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkyl group which has 1 to 4 carbon atoms and which is mono- or disubstituted by halogen, phenyl, halogen, carboxyl, alkoxycarbonyl having 1 to 4 carbon atoms in the alkyl group, trifluoromethyl, nitro, cyano or benzoyl, R.sub.4 and R.sub.5 each represent hydrogen, an alkyl group having 1 to 4 carbon atoms or phenyl, and R.sub.6 has all the meanings given, with the exception of halogen, for R.sub.1, R.sub.2 and R.sub.3 is disclosed.According to this process hydroxydiaryl ethers of the above formula are obtained by reacting a diether of the formula ##STR4## wherein R, n and X have the meanings given above, in a polar aprotic solvent, in the presence of 0.1 to 1 mole of alkali per mole of diether of the above formula, with a dihydroxybenzene of the formula ##STR5## wherein R and n have the meanings given above. The hydroxydiaryl ethers of the above formula can be used as intermediates for the production of .alpha.-(phenoxy-phenoxy)-alkanecarboxylic acid derivatives and .alpha.-(pyridyloxy-phenoxy)-alkane carboxylic acid derivatives, which have a herbicidal and plant-growth-regulating action.

    Abstract: Halobenzenes are manufactured by (a) a one-vessel reaction of anilines with halogenating agents to give haloanilines, followed by reaction of the mixture thus obtained with alkanols and nitrosylating agents in the presence of water and acid at not less than 35.degree. C. or (b) the corresponding reaction of a haloaniline which has been manufactured in the above manner or by some other method and has been isolated from its reaction mixture. The products are starting materials for the manufacture of drugs, dyes and pesticides.

    Abstract: Substituted 2,2''-methylenediphenols which are particularly effective in the treatment of mammals infected with internal parasites, such as, liver-fluke and schistosoma, and which also have anti-bacterial activity, for example, against staphylococcus aureus, have the formula:

    IN WHICH EACH OF X1 and X5 represents a halogen atom or a nitro group, X2 is a halogen atom, each of X3 and X4 is a halogen or hydrogen atom, and X6 is a halogen or hydrogen atom or a nitro group, and further in which at least one of X1,X5 and X6 is a nitro group and, if X1 and X6 each represent a nitro group, then X3 is a halogen atom. Pharmacologically acceptable salts and esters of the foregoing substituted 2,2''-methylenediphenols are also disclosed. The substituted 2,2''-methylenediphenols can be prepared by coupling of the two phenolic moieties by means of a methylene bridge either before or after the introduction of the necessary substituents. Such coupling can be achieved by condensation of a substituted saligenin or saligenin derivative with a phenol under the influence of a suitable condensing agent.
