O-acrylaminomethylbenzyl halides (I) ##STR1## in which X is Cl or Br and R.sup.1 is alkyl or aryl, are obtained by reacting an o-aminomethylbenzyl alkyl ether (II) ##STR2## with an acylating agent, and then reacting the resulting acid amide, preferably without intermediate isolation, with an aqueous hydrohalic acid.

Preparation of o-acylaminomethylbenzyl halides

Etherified polyoxyalkylene derivatives of the formula ##STR1## where R.sup.1 is hydrogen, C.sub.1 -C.sub.20 -alkyl or C.sub.3 -C.sub.5 -alkenyl, R.sup.2 and R.sup.3 independently of one another are each hydrogen, methyl or ethyl, R.sup.4 is C.sub.1 -C.sub.4 -alkyl and m and n are identical or different and are each greater than or equal to 0, with the proviso that the sum of m and n is from 3 to 300, are prepared by reacting the corresponding hydroxyl-containing polyoxyalkylene derivative with a dialkyl sulfate in the presence of an alkali metal hydroxide by a process in which the reaction is carried out at from 20.degree. to 60.degree. C. in the presence of an aqueous solution of an alkali metal hydroxide, the concentration of alkali metal hydroxide during the entire duration of the reaction being not less than 35% by weight, based on the aqueous phase, and not less than 1 mole of dialkyl sulfate and not less than one mole of alkali metal hydroxide are used per mole equivalent of organic hydroxyl groups.

Etherification of polyoxyalkylene derivatives

Detergents which contain from 0.01 to 20% by weight of oxyalkylated, carbonyl-containing polymers can be prepared by reacting. (A) a polymer which contains, as copolymerized units, one or more monoethylenically unsaturated C.sub.3 -C.sub.6 -carboxylic acids with (B) ethylene oxide, propylene oxide, n-butylene oxide, isobutylene oxide or a mixture of these, in an aqueous medium at up to 150.degree. C.

Detergents containing oxyalkylated, carboxyl-containing polymers

Novel aminopropanol derivatives of 2-hydroxy-.beta.-phenyl-propiophenones and their physiologically acceptable acid addition compounds, processes for their preparation and therapeutic agents which contain these derivatives and are useful as antiarrhythmic drugs.

Aminopropanol derivatives of 2-hydroxy-.beta.-phenyl-propiophenones,

o-Acylphenols and p-acylphenols are prepared by reacting phenol with an acid halide and aluminum chloride, using a halobenzene as the solvent, at from 15.degree. to 55.degree. C. and then at from 55.degree. and 200.degree. C. The compounds obtainable by the process of the invention are valuable starting materials for the preparation of drugs, pesticides and dyes.
