摘要： The invention relates to a method for enhancing the cooking step in a tall oil preparation process comprising: a neutralization step in which soap is neutralied to form soap oil, and a cooking step in which soap oil is cooked with sulphuric acid to form tall oil, the soap oil obtained in the neutralization step being subjected to an intermediate treatment before the cooking step, the intermediate treatment comprising heating of the soap oil to release gases dissolved in and bound to the soap oil. The invention also relates to a method for preparing tall oil comprising the steps mentioned above.

摘要： Process for the esterification of organic acids with alcohols in a reactor of the chromatographic type in which the heterogeneous solid phase is capable of acting both as an esterification catalyst and as a means exhibiting preferential adsorption towards one of the reaction products (typically water). The process to which the present invention relates is particularly improved compared with conventional technology owing to the use, as the means for regenerating the catalyst, of a desorbent to which has been added a second compound, generally the anhydride of the acid used in the esterification reaction, which, by chemical reaction, completes the removal of the adsorbed water.

摘要： The process for the recovery of highly fluorinated carboxylic acids from off-gas streams, in which the off-gas is brought into contact with an alkaline washing solution of density >1.15 g/cm3 so that the salt of the highly fluorinated carboxylic acid settles out as a separate phase, proceeds particularly advantageously when the alkaline washing solution is a potassium carbonate solution.
