  • Publication number: 20130153401
    Abstract: A process for purifying a brine of organic compounds comprising: (a) supplying a brine that comprises at least one organic compound; (b) feeding at least one stripping zone with the brine from (a) and at least one stripping agent; (c) withdrawing from the stripping zone at least one fraction (I) consisting essentially of brine, the content of the organic compound being lower in fraction (I) than in the brine from step (a), and at least one fraction (II) consisting essentially of the stripping agent; wherein the temperature (T1) of the hotter fraction of the two fractions (I) and (II) and the temperature (T2) of the colder fraction of the two fractions (I) and (II), such temperatures expressed in degrees Celsius being the temperatures measured before any possible thermal conditioning which might be carried out before and/or during their withdrawal from the stripping zone, correspond to the following formula: 6×10?7(T1)3.

  • Patent number: 7906691
    Abstract: Process for preparing a chlorohydrin, comprising a step in which a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture thereof is subjected to reaction with a chlorinating agent containing hydrogen chloride and at least one other step, carried out in apparatus made from or covered with materials which are resistant to the chlorinating agent under the conditions in which this step is realized.

  • Patent number: 7906692
    Abstract: Process for preparing a chlorohydrin, comprising the following steps: (a) a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture thereof whose alkali metal and/or alkaline earth metal content is less than or equal to 5 g/kg, a chlorinating agent and an organic acid are reacted so as to give a mixture containing at least chlorohydrin and by-products (b) at least part of the mixture obtained in step (a) is subjected to one or more treatments in steps subsequent to step (a) (c) at least one of the steps subsequent to step (a) consists in oxidation at a temperature greater than or equal to 800° C.

  • Patent number: 7893193
    Abstract: Process for preparing a chlorohydrin, comprising the following steps: (a) a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture thereof is reacted with a chlorinating agent and an organic acid so as to give a mixture containing the chlorohydrin and esters of the chlorohydrin (b) at least part of the mixture obtained in step (a) is subjected to one or more treatments in steps subsequent to step (a) (c) polyhydroxylated aliphatic hydrocarbon is added to at least one of the steps subsequent to step (a), so as to react, at a temperature greater than or equal to 20° C., with the esters of the chlorohydrin, so as to form, at least partly, esters of the polyhydroxylated aliphatic hydrocarbon.
