WebbMetylisobutylketon framställs av aceton i en trestegsprocess. Först genomgår aceton en aldolreaktion och bildar diacetonalkohol (C 6 H 11 (OH)O) som kan dehydratiseras till mesityloxid (C 6 H 10 O). Mesityloxiden hydrogeneras sedan till MIBK. WebbEffects on behaviour were reported in baboons exposed for 7 days to 205 mg/m 3 (50 ppm). At a concentration of 4100 mg/m 3 (1000 ppm), MIBK was not embryotoxic, fetotoxic, or teratogenic in rats or mice. Fetotoxicity was only observed at concentrations of MIBK that caused maternal toxicity. MIBK did not induce gene mutations in in vitro ...
