  • Method for Preparing Cationic Galactomannans
    Publication number: 20140243518
    Abstract: The present invention relates to a method for preparing cationic galactomannans, comprising the following steps: a) a step in which galactomannans are impregnated with an alkaline agent; b) a step in which the mixture formed in step a) is impregnated with a cationic agent; and c) a step in which the mixture is formed in step b) is dried.

  • Continuous method for manufacturing betaine aqueous solution
    Patent number: 8766000
    Abstract: The present invention relates to a method for continuously preparing a betaine aqueous solution, including the reaction of an amine with an ?-halocarboxylic acid, in the presence of water and a base. Said method is characterized in that it is carried out in a device consisting of at least two consecutive reactors (R1) and (R2), the reactor (R2) being a tubular reactor.

  • Method for making adipic acid crystals and resulting crystals
    Publication number: 20040242927
    Abstract: The present invention relates to a process for the manufacture of adipic acid crystals and to the crystals obtained. It relates more specifically to a process for the treatment of the adipic acid crystals obtained at the end of crystallization in order to obtain crystals which can be stored with minimum possibility of caking. This process consists of a maturing stage in order to partially remove the water present in the said crystals.
