PROCESS FOR PREPARING β-CAROTIN Russian patent published in 1995 - IPC

Abstract RU 2034835 C1

FIELD: organic chemistry. SUBSTANCE: b-carotin is prepared by reductive dimerization in the presence of a previously prepared active form of low-valent titanium. The process is novel in that it uses, as the active form, low-valent titanium of the reaction mixture resulting from electrochemical dissolution of titanium metal in acetic acid. EFFECT: improved preparation process.
