Preparation of solutions of betaine |
| 摘要 |
<p>Betaine is produced by the oxidation of a choline salt in the presence of a base and a supported noble metal catalyst at temperatures from about 20 DEG C to 100 DEG C and pressures from atmospheric to about 100 psi. This process is advantageous over prior processes for the production of betaine in that no amine halocarboxylate contaminants are produced by this reaction.</p> |
