摘要:
The invention relates to a method for producing alkylene oxide addition products by reaction of compounds having a nucleophilic center with alkylene oxides in a reactor having a large inner surface. The invention is characterized in that the reaction is carried out exclusively in the liquid phase.
摘要:
The invention relates to a composition comprising at least one continuous phase that is liquid or at least deformable in a plastic manner within a temperature range of -10 °C to 50 °C and at least one particulate discontinuous phase which is provided in the continuous phase. The discontinuous phase contains at least 10 percent by weight of an organic compound having a melting point that ranges between 0 °C and 50 °C as a phase change material (PCM) and at least one structuring polymeric compound.
摘要:
The invention relates to a method for the continuous esterification of C1-C22 (fatty) acids with C1-C10 monoalcohols, C2-C5 dialkanols or trialkanols, or mixtures thereof, in the liquid phase, according to the counterflow method, in the presence of heterogeneous catalysts in the upstream reactor (1) and in the reaction column (3). Said method is characterised in that an upstream reactor (1) and a separating unit (2) are mounted upstream of the reaction column (3), in order to reduce the viscosity of the reaction mixture, and the reaction water (3) is extracted from the system by means of the separation unit (2), in order to shift the chemical balance upstream of the reaction column (3).
摘要:
The invention provides a process for preparing ethylene oxide and/or propylene oxide by contacting ethylene and/or propylene with an oxidizing agent, wherein (i) the reaction takes place in a microreaction system (µ-reactor) and (ii) the oxidizing agent used is a peroxo compound.
摘要:
The invention relates to a method for producing starting materials for obtaining conjugated linoleic acid, which is characterized in that: (a) triglycerides, which contain at least 60 wt. % linoleic acid, are interesterified with alcohols having a chain length of C1 to C4 carbon atoms at a temperature ranging from 80 to 120 DEG C, and; (b) the interesterification mixture obtained in such a manner is subjected to a distillation.
