1,3-Dihydroxyacetone
  Assay: 99%   Package: 25kg/drum   MOQ: 1kg
  CAS62147-49-3   MF:C6H12O6   MW:180.16
Other Name: 2,5-Dihydroxy-1,4-dioxane-2,5-dimethanol 1,3-Dihydroxyacetone dimer
Appearance: White powdery crystal, melting point 75-80.
  Production process: In glycerol water containing 15mol% TEMPO, use bicarbonate as buffer electrolyte to make pH 9.1, use Ag/AgCl as electrode, pass 1.1V voltage. After 20h of reaction, the conversion rate of dihydroxyacetone reaches 25%. If the reaction time is prolonged, dihydroxyacetone will further react to generate hydroxypyruvic acid. For example, after 200h of reaction, there is a 35% hydroxypyruvic acid and 30% dihydroxyacetone coexist.
  Preparation: Use hexadecyl benzothiazole ylide reagent as catalyst, dodecanol as solvent, and catalyze 37% formalin solution as DHA. After reacting at 140 °C for 30 min, a 30.4% DHA aqueous solution was obtained, corresponding to a yield of 82%. While using cetylnaphthol thiazole salt as catalyst, triethylamine as cocatalyst, and ethylhexanol as solvent, the reaction was carried out at 100 °C for 30 min, and the yield of DHA could reach 77.9%. Formaldehyde was reacted with thiamine hydrochloride (vitamin B1 hydrochloride) as catalyst, triethylamine as cocatalyst, and N,N-dimethylformamide as solvent at 100 °C for 1 h. , the conversion rate of formaldehyde is 98%, and the selectivity of DHA is 89%.
  Application: 1,3-Dihydroxyacetone is the simplest three-carbon ketose. Dihydroxyacetone is an important biochemical raw material and synthetic reagent, which is used in many industries such as fine chemical industry, food industry, cosmetics industry and so on.
