    Abstract: Alkanes bearing chlorine atoms and/or sulfochloride groups as substituents are prepared by the reaction of alkanes with chlorine with or without sulfur dioxide in a specific throughput ratio and in a reactor inclined to the horizontal, the starting materials being passed cocurrent upwardly through the reaction zone. The products are pesticides, plasticizers, solvents and starting materials for the production of the same and also of fat-liquoring agents for leather, detergents, lubricants and synthetic resins.

    Abstract: An improved process for the continuous production of Alpha chloropropionic acid by reaction of propionic acid with chlorine in the presence of halides or acid halides of the elements phosphorus and sulfur at elevated temperature, the improvement consisting in carrying out the reaction in the presence of Alpha -chloropropionic acid as solvent and distilling the resultant reaction mixture using the gas formed in the reaction as carrier gas. Alpha -chloropropionic acid is used for the production of plant protection agents.

    Abstract: A process for continuous production of b -chloroethane sulphochloride comprises continuously passing ethyl chloride, sulphur dioxide and chlorine into a mixture of b -chloroethane sulphochloride, 1,1-dichloroethane, ethyl chloride and sulphur dioxide, and irradiating the mixture, then fractionally distilling it, unreacted materials being returned to the reactor. Suitable radiation is provided by an incandescent lamp of high luminous intensity, a mercury vapour lamp, or any other source of actinic radiation. The initial mixture preferably contains at least 20% of product in order to facilitate solution of sulphur dioxide. The chlorine is supplied in amount such that it is completely used up during irradiation. Reaction temperatures are preferably between -10 and +10 DEG C. An example gives details of the process, in which the mixture is circulated through vertical and horizontal tubes, the sulphur dioxide and ethyl chloride being introduced into the bottom of the upward limb, the chlorine a little higher, all dissolving completely before being irradiated with UV light. After irradiation, hydrogen chloride is removed from the top of the apparatus, and excess sulphur dioxide and ethyl chloride separated and returned to the reactor. Reaction mixture is removed at a rate corresponding to the input of reactants, and is fractionally distilled, sulphur dioxide and ethyl chloride and any 1,1-dichloroethane being returned to the circulating liquid.

    Abstract: Mucochloric acid is prepared by a continuous process by the reaction of furfurol with at least 5 moles of gaseous Cl2 per mole of furfurol in aqueous acid medium by continuously supplying the reactants and continuously withdrawing the reaction product, the reaction mixture being circulated at from ambient temperature to 130 DEG C. in a tubular recirculation system, the reactants being supplied at such a rate that the weight ratio of the furfurol added to the reaction mixture which absorbs it is constantly less than a value of 1:100.

    Abstract: a ,a -Dichloropropionic acid is prepared by chlorinating a -chloropropionic acid at 160 DEG -180 DEG C., or chlorinating propionic acid at about 120 DEG C. to form a -chloropropionic acid and further chlorinating as above, in the presence of a compound RNHSO2X, where R is hydrogen or alkyl and X is hydroxy, alkoxy or a halogen. Specified catalysts are sulphamic acid, its acid chloride and its esters, e.g. H2NSO3CH3 and C2H5NHSO2Cl; these may be formed in situ, e.g. the last from ethylamine and sulphuryl chloride. Other organic additives which boil above a ,a -dichloropropionic acid and are soluble in the chlorination mixture may be present, e.g. aliphatic or aromatic sulphochlorides.
