A process for producing glucoprotamines by condensation of N-substituted propylene diamines with,-aminoglutaric compounds in which the reaction is carried out in the presence of aminosilicones is disclosed. Glucoprotamines produced in accordance with the disclosed process exhibit improved color quality and longer storage stability.

Method for producing glucoprotamines

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.

Process for the production of Guerbet alcohols

The invention relates to the use of selected carboxylic acid esters which are liquid under reaction conditions and correspond to general formula (I)

Process for the sulfonation and/or sulfatization of organic components

Process for the conversion of an organophosphonic acid of the formula ##STR1## in which n=3-5 and R=H or C.sub.1 -C.sub.3 alkyl, into an alkali metal or ammonium salt comprising reacting the moist filter cake which accumulates during the production of organophosphonic acids by known processes (water content 10 to 40% by weight) with anhydrous or concentrated aqueous alkali metal hydroxide or ammonia and exposing the paste formed, which has a water content of from 20 to 80% by weight, to intense shear forces in mixing, dispersing, or kneading units, water being removed from the paste under reduced pressure and with application of heat until the paste changes into a free-flowing powder.
