Abstract
The technology for the synthesis of 2,2,4-trimethylpentane-1,3-diol using indastrial isobutyraldehyde and sodium hydroxide is presented. The optimum reaction condition is that the mole ratio of reactants isobutyraldehyde: sodium hydroxide: sodium hydroxide = 40: 1: 14,reaction temperature 28~52℃ for 1~2h in frist step, and 90~140℃ for 6~8h in second step. The yield of the product is above 60% ( to total slock) and mass percentage is over 97%. The methods of purifying products are developed too.
