Abstract: Granular potassium sorbate is continuously manufactured by spraying an aqueous potassium sorbate solution into or onto a bed of potassium sorbate particles fluidized by heated air.

Abstract: Preparation of naphthalene-monosulfonic acids from naphthalene and sulfuric acid at elevated temperatures.

Abstract: Continuous preparation of mono- or di-(trichloromethyl)-benzenes or of mono- or di-(trichloromethyl)-benzenes substituted in the benzene ring by halogen atoms from the corresponding mono- or dimethylbenzenes and chlorine in several steps with radiation by means of rays of high energy, is effected by reacting mono- or dimethylbenzene with chlorine in 4 to 14 steps, at a temperature in the range of from 20.degree. to 130.degree. C, whereby chlorine is introduced into the second step and the following steps, the resulting waste gas is introduced into step 1 and chlorine contained in the waste gas is reacted in reactor 1 with fresh mono- and dimethylbenzene. A preferred embodiment for carrying out the process is reaction in a reactor arrangement in cascade form, wherein the number of steps corresponds to the number of reactors and wherein as reactors circulation reactors are used.

Abstract: Preparation of derivatives of benzene containing CF.sub.3 groups from the corresponding compounds containing CCl.sub.3 groups (e.g. trichloromethyl benzene) is carried out continuously with excellent yield rates by reaction with liquid hydrogen fluoride in an autoclave above 80.degree.C, (which latter exceeds the stoichiometric proportion by at least 25 mole %). The reactants are fed continuously into the autoclave. The reaction mixture preferably becomes pressurized to at least 20 atmospheres and homogeneous after having reached a certain filling level. The reaction mixture is thereafter withdrawn proportionally to its feeding-in rate. The mixture may be conveyed through one or several additional autoclaves with the final withdrawal of the reaction mixture being out from the terminal autoclave of this cascade. The fluorination products are well known starting and inermediate products for the preparation of dyestuffs and pesticidal compositions.

Abstract: The hydrochloride of 5-chloro-2-toluidine is obtained by dispersing 2-toluidine hydrochloride in a halohydrocarbon and reacting it with chlorine. No isomers are formed and very little higher chlorinated products. 5-chloro-2-toluidine is easily set free from the hydrochloride with aqueous bases.
