PRODUCTION OF D,L-MENTHOL FROM D-MENTHOL
Continuous process for prodn. of d,l-menthol by catalytic conversion of optically active d-menthol in the presence of hydrogen at a H2 press. of 50-350 bar and a temp. of 200-350 degrees C over a solid catalyst bed of carrier-free catalyst bodies obtd. by redn. of pressed bodies of powdered Ni-, Mn-...
