A solidification and curing accelerator for hydraulic binders produced by a process including providing a reaction mixture composed of constituents (a) - (e) as follows: (a) at least one of basic aluminum salts which are substantially water insoluble and aluminum hydroxide; (b) at least one of aluminum sulfate which is substantially water soluble and sulfuric acid; (c) at least one of an organic carboxylic acid or mixtures of at least two organic carboxylic acids; (d) aluminum salts of organic carboxylic acids; and (e) at least one organic and inorganic substance selected from the group consisting of sulfates, hydrogen-sulfates, carbonates, hydrogen-carbonates, alkaline earth metal oxides, and alkaline earth metal hydroxides; adding water to the reaction mixture and reacting at a temperature ranging up to 150 &deg; C. for a time effective to provide a reaction product which is a solution in water.

The invention relates to a process for the production of Guerbet alcohols by condensation of aliphatic alcohols in the presence of alkali metal or alkaline earth metal hydroxides as catalyst using the Guerbet reaction, in which the initial pressure in the reactor corresponds to the vapor pressure of the alcohol components used and, during the reaction, the pressure is continually reduced to the vapor pressure of the reaction mixture at the particular temperature.

The glycerol water (sweet water) accumulating in the high-pressure hydrolysis of natural fats and oils with steam into fatty acid and glycerol is continuously purified. Fats larger than 100 .mu.m in diameter are separated from the aqueous phase in a plate-type phase separator and are returned to the high-pressure hydrolysis process. The aqueous phase thus prepurified is passed through a cross-flow filtration membrane, more particularly a microfiltration membrane, and the concentrate is returned to the entrance of the plate-phase separator. Large product streams of glycerol water can be purified continuously, effectively and particularly economically despite frequent changes of provenance.

The invention relates to a process, more especially a discontinuous process, for conducting a reaction taking place at elevated temperature in which heat-sensitive products are formed. To increase the volume-time yield, a heat transfer unit independent of the reactor is used for heating. The invention also relates to an apparatus for the production of heat-sensitive products at elevated temperatures. This apparatus comprises a reactor and a heating system. To increase the volume-time yield, the heating system comprises at least one heat transfer unit arranged outside and connected to the reactor.
