    Abstract: PROBLEM TO BE SOLVED: To provide an industrial preparation process of a polycarbonate diol, in which a less-colored high-quality polycarbonate diol having a hydroxy group on its molecular terminal is obtained by reacting dimethyl carbonate with an aliphatic dihydroxy compound. SOLUTION: A polycarbonate diol prepolymer whose terminal alkyl group ratio in mol is not more than 5% is obtained by reacting dimethyl carbonate with an aliphatic dihydroxy compound in the presence of a catalyst, keeping the reacting mol ratio r to be 1.31-1.58 by stripping the mixture of methanol and dimethyl carbonate. A polycarbonate diol is obtained by further carrying out a polycondensation reaction of the prepolymer in the presence of a catalyst the aliphatic dihydroxy compound.
