Process for the preparation of aqueous betaine solutions. |
| abstract |
PROCESS FOR THE PREPARATION OF AQUEOUS BETAINE SOLUTIONS. Betaine is produced by the oxidation of a choline salt in the presence of a supported noble metal catalyst at temperatures of about 20 ° C to 100 ° C and pressures, from atmospheric to about 7 kg / cm². This process is advantageous over previous processes for the production of betaine in that amine halocarboxylate contaminants are not produced by this reaction. |
