    摘要： A process and apparatus for the continuous production of alkylesters of saturated aliphatic carboxylic acids by reacting olefins with carbon monoxide and alkanol in the presence of a catalyst consisting of a cobalt compound and a promoter selected from the group consisting of pyridine, non-ortho-substituted alkylpyridines and mixtures at elevated pressure and elevated temperature, the reaction based on olefins having at least 8 C atoms and being carried out in a reactor wherein the flow characteristic is adjusted so that tubular flow without back-mixing predominates, and wherein the raw materials are supplied in the desired ratios at the input side of the reactor.

    摘要： A process for preparing fatty acid esters by reacting olefins, alkanols and carbon monoxide in the presence of a compound of cobalt and a promoter consisting of pyridine, non-orthosubstituted alkylpyridines or mixtures thereof. The reaction output is at first treated with a gas containing oxygen in a non-damaging manner and then reprocessed in two distillation stages. The first distillation stage is operated at a higher pressure than the second. In the first distillation stage there is produced a distillate free of cobalt and a sump product containing all of the cobalt used as catalyst. In the second distillation stage the sump product of the first distillation stage is again distilled to produce another distillate free of cobalt and a cobalt concentrate as sump product. This cobalt concentrate is incorporated into pyridine, a non-orthosubstituted alkylpyridine or a mixture thereof to form a suspension. The suspension is then treated by a mixture of carbon monoxide and hydrogen at a temperature of 100.degree. to 250.degree. C. and a pressure at least 50 bars, and this treatment product is fed back into the fatty acid ester synthesis.

    摘要： In tire chains, closures are required to lock tension-chain lines (10) in the tensioned position. A proposed closure is provided with a pull-through orifice (2) for the tension-chain line (10) and with a locking slot (3) adjacent to the pull-through orifice (2). To prevent the particular chain link (9) suspended in the locking slot (3) from working loose, the pull-through orifice (2) is equipped with an elastic insert (11) which forms at least one engagement cam projecting into the locking slot (3).
