실험 절차

A mixture of cyclohexanone (52 ml, 0.5 mol), trimethylorthoformate (66 ml, 0.6 mol), methanol (51 ml, 1.26 mol) and concentrated H2SO4 (1 drop) was refluxed for 18 hours. A solution sodium methoxide in methanol was added until the mi was neutral, and the mixture was fractionally distilled. 1,1-Dimethoxycyclohexane was obtained from the fraction b.p. 162°-164° C. (50.6 g, 70%).
