摘要： Apparatus for solvent extraction of a mother liquor with a solvent that is immiscible with and has a different specific gravity than the mother liquor, is disclosed. Means are provided for introducing into an extraction chamber, the solvent, the mother liquor and a carrier gas. Such means simultaneously serve to atomize the solvent and the mother liquor and disperse same in the carrier gas whereby upon introduction a cloud phase is produced in the chamber.The introducing and simultaneously atomizing is carried out through one and the same spray nozzle. Condensation means are arranged in the extraction chamber and function to terminate the cloud phase and produce a condensed extracted mother liquor phase and a condensed solvent phase containing the substance to be extracted. Means are provided for separating the condensed extracted mother liquor phase from the condensed solvent phase on the basis of the different specific gravities of same.

摘要： Various chloroformates are produced from aliphatic, substituted aliphatic, cycloaliphatic, aromatic and arylaliphatic alcohols having up to 20 carbon atoms and of phosgene in a continuous, concurrent flow process, with the alcohol starting material being atomized into the reactor, whereby the reaction takes place largely in the fog phase. The vapor pressure of the phosgene can be utilized for the creation of the fog phase and the termination of the atomized state can be used for efficiently separating the chloroformate end product from the hydrogen chloride by product. The process can be carried out in a reactor comprising a reaction zone, a charged zone and a zone for the recovery of the end product.

摘要： The invention relates to a novel process for preparing chloroacetanilides of the formula ##STR1## wherein: R.sub.1 and R.sub.2 represent independently from each other a hydrogen atom or a C.sub.1-8 alkyl or C.sub.1-8 alkoxy group; andR.sub.3 stands for a straight chained or branched C.sub.1-8 alkoxy group.Said process is characterized by chloroacetylating a 2,6-dialkylaniline of the formula ##STR2## wherein R.sub.1 and R.sub.2 are as defined above, at a temperature of 10.degree. to 120.degree. C., optionally in a solvent medium in the presence of an acid binding agent, then reacting a thus-obtained intermediate with chloromethyl chloroformiate or, alternatively, reacting a compound of the formula (II) first with chloromethyl chloroformiate and subjecting then to chloroacetylation, thereafter reacting a thus-obtained intermediate with an alcohol of the formulaR.sub.3 --OH (III),wherein R.sub.3 is as defined above, optionally in a solvent medium in the presence of an acid binding agent, and recovering a product of the formula (I) in a known manner.The process of the invention enables the more simple and economic preparation of the compounds of formula (I) of improved purity.
